Most people in Pakistan never think about how many SIMs are active on their CNIC until something feels off. A stranger calls from a number that looks familiar but belongs to no one you know. A family member mentions that someone was using your identity for a mobile connection. Or you simply realize that over the last several years, you have gone through four or five SIM cards — and you have no idea how many of them are still registered in your name.
The 668 sim check was built for exactly this moment.
By sending your CNIC number to the shortcode 668, you get a reply showing how many SIMs are currently linked to your identity, broken down by operator. No app download. No login portal. No complicated process. A single SMS gives you a count that tells you where things stand.
What makes the 668 sim check worth understanding properly is not just how to use it — it is also knowing what it cannot do. This service tells you how many SIMs are registered on your own CNIC. It does not tell you who owns a random phone number. It cannot pull up someone else’s address, CNIC, family details, or call records. Any third-party service claiming to do those things through 668 or a similar method is not operating through an official system — and in many cases, it is not operating legally either.
Pakistan has a large number of unofficial websites and WhatsApp agents that advertise “SIM owner details,” “fresh SIM data,” or “CNIC lookup by number.” These are not the 668 sim check. They have nothing to do with PTA’s official SIM verification framework. Using them puts your own data at risk. For safer options than database-style searches, read the Pak SIM Data safe alternatives guide.
The right way to use the 668 sim check is simple: send your own CNIC, review the response, and take action through official operator channels if something does not add up. That is the full scope of what this service is designed for — and it is genuinely useful within those boundaries.
This guide explains the complete picture: how the 668 sim check works, what it shows, what to do with the information, how it compares to cnic.sims.pk, and what steps to take if you find something on your CNIC that should not be there.
Quick Answer: What Does 668 SIM Check Do?
The 668 sim check is an SMS-based service that allows Pakistani CNIC holders to find out how many mobile SIM connections are currently registered under their own CNIC. Send your 13-digit CNIC (without dashes) to 668, and you receive an operator-wise count in reply. The 668 sim check does not show the name, CNIC, or address of any other person — it is strictly a personal SIM count tool for your own identity. For action on any unknown SIM, use official operator channels or cnic.sims.pk only.

What Is 668 SIM Check in Pakistan?
Pakistan runs one of the region’s more structured SIM registration systems. Every mobile SIM sold in the country must be registered against the buyer’s CNIC through biometric verification at an authorized franchise. NADRA’s fingerprint database is used to confirm identity, and the SIM is then linked directly to that CNIC in the operator’s records. This means every mobile connection carries a direct identity trail.
The 668 sim check is the consumer-facing part of that system — the part that lets you look at your own records.
When you run a 668 sim check, you are sending a query to the SIM verification infrastructure that says: show me how many connections are registered under this CNIC. The response comes back as an SMS with an operator-wise breakdown. If your CNIC has two Jazz SIMs and one Zong SIM, those counts appear in the reply.
Understanding what the 668 sim check actually is helps you understand what it is not. It is not a reverse phone number lookup. It is not a SIM owner database. It does not index mobile numbers and connect them to names, addresses, or family records. The system only responds to queries about your own CNIC — and even then, it returns counts, not personal details about specific SIM users.
The concept behind the 668 sim check is straightforward: because your CNIC is legally tied to every SIM registered in your name, you have the right to know how many connections currently exist under that CNIC. That visibility is the entire purpose of the service.
There are a few related points worth understanding before you use it:
It is personal, not public. The 668 sim check is designed for individual CNIC holders checking their own records. It is not a service for researching other people’s mobile connections.
It covers all major Pakistani networks. The SIM count you receive typically covers connections across Jazz, Zong, Telenor, Ufone, and other registered operators, though the exact format of the reply may vary.
It does not process the inquiry instantly through a database you control. You send the SMS, and the response comes from the telecom system — you are not browsing a database yourself.
It is a starting point, not a resolution tool. If the 668 sim check reveals a count that does not match your actual SIMs, the resolution happens at an official operator franchise — not through another SMS.
The 668 sim check sits within Pakistan’s broader SIM verification ecosystem, which also includes services like cnic.sims.pk for web-based access. Both tools serve the same core purpose: giving CNIC holders visibility into the mobile connections registered under their identity, so they can catch and address problems early.
People use the 668 sim check for a wide range of practical reasons — confirming they are within PTA’s registration limits before getting a new SIM, checking whether an old number from years ago is still active, reviewing connections after a CNIC replacement, or simply doing a periodic check as a matter of personal digital hygiene. All of these are legitimate uses within the boundaries of what the service is designed to do.
Why 668 SIM Check Matters for Pakistani Users
There is a gap between how SIM registration is supposed to work in Pakistan and how it sometimes works in practice. In theory, every SIM is linked to a verified CNIC owner who consented to the registration. In practice, CNICs get photocopied at franchises, shared within families, borrowed carelessly, or — in the worst cases — misused through document fraud.
For a full CNIC-based SIM audit, follow our CNIC SIM check guide.
The 668 sim check matters because it gives ordinary users a way to see exactly where they stand.
The forgotten SIM problem is real. Pakistani mobile users frequently switch networks, change phones, and abandon old SIM cards without formally deregistering them. A SIM purchased five years ago on a different network may still be active and registered on your CNIC. You may not remember it exists — but it does, and it counts toward your registration limit.
Family SIM arrangements create complications. Many Pakistani households registered SIMs on a parent’s CNIC for younger family members before those family members had their own CNICs. That was practical at the time. Years later, those SIMs may still be active on the original CNIC, and no one has tracked them carefully. A 668 sim check brings all of that into view.
CNIC misuse happens. Cases of fraudulent SIM registration through misused CNIC documents are documented. Franchise employees, document intermediaries, or identity thieves have registered SIMs on CNICs without the owner’s knowledge or consent. Without a periodic 668 sim check, these connections can remain invisible for years.
The registration limit has real consequences. PTA places a maximum on how many SIMs a single CNIC can hold. Users who are at or near that limit without knowing it may find themselves unable to register new SIMs. Running a 668 sim check resolves that uncertainty immediately.
Without official methods, people use dangerous alternatives. When users do not know about the 668 sim check or cnic.sims.pk, they search online and often land on fake SIM database websites. These sites collect CNIC data, generate fabricated results, and sometimes operate as phishing tools. Knowing and using the official method eliminates that risk entirely.
The 668 sim check is not just a technical feature — it is a practical tool for staying in control of your mobile identity. Running it occasionally, especially after major life events like a CNIC renewal, a phone change, or a city move, is straightforward and takes less than two minutes.
How to Use 668 SIM Check on Your CNIC
The 668 sim check works through a standard SMS. No internet connection is required. No special app needs to be installed. Any Pakistani mobile number on any active network can send the query.
To confirm a number’s current network, use the 76367 network check.
Here is the step-by-step process:
1. Open your phone’s SMS app.Use the standard messaging application on your phone. It does not matter which network your SIM is on — the 668 sim check can be initiated from Jazz, Zong, Telenor, Ufone, or any other Pakistani operator.
2. Create a new message and type your CNIC number without dashes.Your CNIC is printed in the format 12345-1234567-1. For the 668 sim check, remove all dashes and type only the 13 digits consecutively.
Example format: If your CNIC is 35202-1234567-9 (not a real CNIC), type it as 3520212345679. Make sure there are no spaces, dashes, or extra characters.
3. Send the message to 668.Type 668 in the recipient field and send the SMS.
4. Wait for the reply.The 668 sim check response comes back as an SMS within a short time. The message will show the count of SIM connections registered on your CNIC, broken down by operator.
5. Review the operator-wise count carefully.Go through the result of your 668 sim check and compare each operator’s count with the SIMs you know you own. Count everything — the SIM in your current phone, any spare SIMs, old devices in a drawer.
6. Take action if the numbers do not match.If your 668 sim check shows a count higher than expected for any operator, that is your signal to follow up. Contact the relevant operator’s official franchise or customer support — not a random website, not a WhatsApp agent.
⚠️ Before you send:
- Use only your own CNIC for the 668 sim check. Sending someone else’s CNIC is inappropriate and may have legal implications.
- Standard SMS charges may apply. Charges can vary by operator and may change over time.
- The exact process, charges, and reply format of the 668 sim check can be updated. Always verify current details from your mobile operator or an official PTA-related source before relying on this guide as the definitive instruction.
What the 668 sim check reply looks like:The response typically lists operators alongside SIM counts — something like “Jazz: 2, Zong: 1, Telenor: 0” (the exact format may vary). It does not list the specific mobile numbers or names associated with those SIMs. The 668 sim check gives you the count, and from there, you decide whether to investigate further.
One practical note on timing: The 668 sim check result reflects current registered connections, not historical ones. If you disowned a SIM last month, it should not appear in today’s count. If you got a new SIM two weeks ago, it should be reflected. If something does not match expectations, a franchise visit will clarify the specific details.
The simplicity of the 668 sim check is one of its strongest points. For most users, the entire process — sending the SMS and reviewing the reply — takes under two minutes.
Alternative Method to 668 SIM Check: cnic.sims.pk
The cnic.sims.pk portal offers a web-based alternative for users who prefer an online interface over the SMS method of the 668 sim check. The portal allows you to enter your CNIC details and view registered SIM connections, and in some cases, it provides options to initiate a disown request directly.
For users who want more than just a count — or who want a visual interface for reviewing their SIM registrations — cnic.sims.pk can be a useful complement to the 668 sim check.
That said, the online route comes with its own cautions that are worth taking seriously.
Verify the domain before entering anything. Fake copies of official portals exist. The domain name should be checked carefully — typos and lookalike domains have been used to harvest personal data. Type the address directly into your browser rather than clicking links shared on social media or in WhatsApp groups.
Before using any online SIM check page, confirm:
- The domain spelling is exactly correct
- You reached the page by typing the URL directly, not through a shared link or ad
- The page does not ask for unnecessary information such as passwords, bank details, or full family CNIC data
- The page does not promise “SIM owner details by number” or private data lookup — those are not official features of any legitimate SIM check portal
- No one is asking you to pay a fee to access the results
- No one is asking you to share an OTP to “verify” your identity to a third party
What legitimate portals will and will not do. A genuine SIM check portal shows your own CNIC-linked SIM count. It will not promise to show you who owns a random phone number. It will not offer to reveal private identity records of other people. If a page is making those claims while styling itself as an official SIM check tool, it is not official.
The 668 sim check and cnic.sims.pk serve the same core function through different channels. Both are for personal CNIC management — not for investigating other people.
Apni CNIC sirf verified official portals par enter karein — random pages ya shared links par trust karna risky ho sakta hai.
What Information Can You Get from 668 SIM Check?
There is consistent confusion about what the 668 sim check actually returns. This table covers the key data points directly:
| Information Type | Usually Available? | Plain Explanation |
|---|---|---|
| SIM count on your CNIC | ✅ Yes | Total active connections registered to your CNIC |
| Operator-wise SIM count | ✅ Yes | Breakdown by Jazz, Zong, Telenor, Ufone, etc. |
| Exact mobile numbers | ❌ No | Specific phone numbers are not shown |
| Owner name of any number | ❌ No | Not a name lookup feature |
| Another person’s CNIC | ❌ No | Protected — not accessible through this system |
| Home address | ❌ No | Not part of this service |
| Live location | ❌ No | Cannot be accessed via SMS or this type of portal |
| Call records | ❌ No | Requires court-authorized law enforcement access |
| WhatsApp data | ❌ No | Completely outside this system’s scope |
| Disowning status | ❌ No | Requires a separate process through operator or portal |
| Biometric correction | ❌ No | Requires a franchise visit |
The 668 sim check is a count-based awareness tool. It confirms how many SIMs are registered under your CNIC across Pakistani operators. It is not a private data search engine, and treating it as one leads to confusion and, sometimes, people turning to unsafe alternatives when the 668 sim check does not deliver what they incorrectly expected.
If you want to know the exact SIM numbers registered on your CNIC — not just the count — a visit to the relevant operator’s franchise with your original CNIC is the appropriate route. The 668 sim check gives you the signal; the franchise gives you the specifics.
What 668 SIM Check Cannot Do
Stating the limitations of the 668 sim check clearly is not just a compliance exercise — it protects people from wasting time and from ending up on unsafe platforms when the 668 sim check does not do what they expected.
See our Disclaimer for important limitations.
It cannot identify a stranger from their phone number. If you receive a call from an unknown number and want to find out who is calling, the 668 sim check is not the tool for that. It only processes your own CNIC to return your own SIM count.
It cannot show someone else’s CNIC. CNIC data is protected personal information. No official Pakistani SMS shortcode provides access to another person’s CNIC.
It cannot show a person’s home address or family connections. These are private identity details that no legitimate SIM check service returns — through 668 or any other official channel.
It cannot show live location or call records. Accessing location data or call history requires a legal and law enforcement process. It is not possible through any SMS service or SIM check portal.
It cannot remove a SIM automatically. Discovering an unknown SIM through the 668 sim check is step one of a process — not the resolution itself. Removing or disowning a SIM requires going through the operator franchise or official disown channel.
It cannot replace the franchise visit when action is needed. For any real correction to CNIC-linked SIM records, you need to appear in person at the relevant operator’s franchise with your original CNIC and biometric verification.
It cannot serve as a SIM database. Pakistan has many websites positioning themselves as SIM databases — searchable tools where anyone can type a phone number and retrieve owner details. The 668 sim check has nothing to do with those platforms. If a site claims to use “668 data” to show you private owner information, that claim is false.
667 vs 668: The Difference Most People Confuse
Both shortcodes come up in Pakistani SIM-related searches, and they are regularly confused. Understanding the distinction helps you use the right tool for the right purpose.
For SIM-in-hand registration details, read our 667 sim information guide.
| Feature | 667 | 668 |
|---|---|---|
| Main use | Check registration status of the SIM in your phone | Check SIM count across your entire CNIC |
| What it checks | One specific active SIM | All SIMs linked to your CNIC |
| Input | Typically no CNIC input required | Your own 13-digit CNIC number |
| Result type | Registration status of one connection | Operator-wise count of all CNIC-linked connections |
| Best for | Confirming your current SIM is properly registered | Spotting unknown or excess SIMs on your CNIC |
| Privacy boundary | Your own SIM only | Your own CNIC only |
| Common misunderstanding | Can identify the owner of any number entered | Can look up private data for any phone number |
| Safe use | Use with your own active SIM only | Use with your own CNIC number only |
The core distinction is scope. Use 667 when you want to verify one specific SIM you currently hold. Use the 668 sim check when you want to see the complete SIM picture for your entire CNIC across all operators.
Neither is a tool for researching other people. Both are personal verification services designed for individual CNIC holders managing their own mobile connections.
What to Do If 668 SIM Check Shows an Unknown SIM
Finding an unexpected count in your 668 sim check result can be unsettling. The right response is measured and methodical — not panicked, and definitely not a search for answers on unverified websites.
1. Stay calm and save the result.Screenshot the 668 sim check SMS reply or note the operator-wise counts. This becomes your reference going forward.
2. Account for all your own SIMs first.Before assuming fraud, go through every SIM you currently have — old phones, spare SIMs, family members whose SIMs may be on your CNIC from years ago. Sometimes the 668 sim check result is accurate and the discrepancy is a forgotten connection.
3. Do not search for answers on random websites.The temptation to Google the problem is understandable, but many results will lead to fake SIM data sites that collect CNIC information. The 668 sim check has already done its job — the next steps are offline.
4. Identify which operator’s count looks unfamiliar.If the 668 sim check shows one extra SIM under Telenor, for example, Telenor’s official franchise is where you need to go.
5. Visit the relevant operator’s official franchise with your original CNIC.Bring the original document — not a photocopy. Explain that your 668 sim check result shows an unexpected count and you want to verify which connections are registered under your CNIC.
6. Request biometric verification.The franchise can confirm your identity through fingerprint and review which SIM connections are linked to your CNIC in their system.
7. Request disowning or blocking of unauthorized SIMs.If a connection is confirmed as unauthorized, you can formally request its disowning. The franchise staff will guide you through the process.
8. Get a reference or complaint number.Always leave with written confirmation — a reference number, receipt, or complaint record. Without documentation, following up becomes significantly harder.
9. Follow up if the issue is not resolved promptly.If the operator franchise does not resolve the matter, escalate through PTA’s official consumer complaint channel. Check PTA’s official website for the current process.
Only official operator channels can properly verify, correct, block, or disown SIM connections on your CNIC. No third-party website or paid agent can do this safely on your behalf.
Network-Wise Guidance After a 668 SIM Check
Jazz SIMs on Your CNIC
If your 668 sim check reply shows a Jazz SIM count that does not match what you own, the next step is an official Jazz franchise or experience center. Take your original CNIC and ask to verify which Jazz SIMs are registered under your identity. If any are unauthorized, request the formal disowning process with biometric confirmation. Current franchise locations and support details should be verified from Jazz’s official website — contact information on social media or third-party directories may be outdated.
Zong SIMs on Your CNIC
An unexpected Zong count in your 668 sim check result means a visit to a Zong customer service center. Staff can check your CNIC-linked Zong connections and initiate a biometric verification. If a SIM on your CNIC is not yours, the franchise can begin the disowning process. Always get Zong’s current contact details from their official website rather than from WhatsApp groups or unverified sources.
Telenor SIMs on Your CNIC
Telenor has official service centers and franchise locations across Pakistan. If the 668 sim check shows an unexpected Telenor count, visit the nearest official outlet with your original CNIC. Biometric re-verification is typically part of the correction process. Current service center locations and contact details are on Telenor’s official website — check there for the most up-to-date information.
Ufone SIMs on Your CNIC
For an unexpected Ufone count after your 668 sim check, head to an official Ufone service center with your original CNIC. The process follows the same pattern — biometric verification, identification of the registered SIMs, and a formal disowning request if correction is needed. Verify Ufone’s current franchise details from their official website before visiting.
ONIC SIMs on Your CNIC
ONIC operates as a digital-first network. If your 668 sim check result includes an ONIC SIM you do not recognize, reach out through ONIC’s official app or website support channel. Biometric verification through official means is the correct route for resolving any registration discrepancy on your CNIC.
SCO SIMs on Your CNIC
SCO primarily serves AJK and Gilgit-Baltistan. If the 668 sim check shows an SCO connection you cannot account for, contact SCO through their official service centers in those regions. As with all operators, bring your original CNIC and verify current service center information through SCO’s official website.
Common Mistakes to Avoid During 668 SIM Check
These mistakes are common enough that covering them in detail is worth the space.
Using fake SIM owner websites instead of the 668 sim check. Pakistan has a large number of unofficial websites claiming to offer “SIM owner details by number” or “CNIC SIM database” services. These are not the 668 sim check. They are not official, not accurate, and often not safe to use. Many collect the CNIC or phone number you enter for their own purposes.
Trying to look up someone else’s SIM details. The 668 sim check only works with your own CNIC. A common misconception is that typing a phone number into 668 will reveal its owner — that is not how the service works, and trying to access someone else’s private data through unofficial channels creates legal exposure.
Entering your CNIC on unverified online tools. Your CNIC is a sensitive identifier. Entering it into a random website — even one that looks official — risks having it collected and misused. The 668 sim check via SMS does not require you to visit any website.
Sharing OTP with anyone. No legitimate process connected to the 668 sim check or cnic.sims.pk requires you to share a one-time password with another person. If a caller or message asks for your OTP, that is a scam regardless of how they identify themselves.
Paying WhatsApp agents for SIM data. Agents advertising CNIC-based SIM lookup or “disowning services” for a fee are operating outside official channels. The 668 sim check and official franchise visits are the legitimate routes — neither requires payment to a middleman.
Trusting leaked database screenshots. Social media accounts occasionally share screenshots purporting to show CNIC-linked SIM data. These are either fabricated, illegally obtained, or severely outdated. Do not treat them as reliable.
Confusing 667 with 668. Using the wrong shortcode gives you the wrong type of information and can lead to unnecessary confusion. 667 checks one specific SIM; the 668 sim check covers your entire CNIC.
Ignoring an unexpected count. If the 668 sim check shows more SIMs than you own, that is a signal that requires follow-up — not something to dismiss. An unauthorized SIM on your CNIC carries real identity risk.
Not visiting the operator franchise. The 668 sim check identifies the issue. Resolving it always requires going through official operator channels — a franchise visit, not another online search.
Not keeping records. If you visit a franchise to address an issue found through the 668 sim check, always leave with a reference number or written confirmation. It protects you if follow-up is needed.
Is 668 SIM Check Legal in Pakistan?
Using the 668 sim check through official channels — sending your own CNIC to 668 and reviewing the response — is entirely legal and actively encouraged. PTA’s SIM verification system exists to give CNIC holders visibility into their registered mobile connections. The 668 sim check is a consumer-facing part of that system.
The legal boundary is crossed when people attempt to access another person’s private mobile identity through unofficial tools. Trying to find a stranger’s CNIC, address, call history, or location data through unauthorized means is not what the 668 sim check is for — and depending on how it is done and what data is accessed, it can fall under Pakistan’s Prevention of Electronic Crimes Act (PECA) and related privacy provisions.
PECA covers unauthorized access to personal data, identity fraud, and digital privacy violations. Using or promoting services that illegally compile and distribute CNIC-linked personal data — the kind of sites that offer “SIM owner databases” — falls into territory that these laws address.
The 668 sim check keeps you firmly on the right side of that line. It is a self-service tool for your own identity — not a surveillance tool for others.
“Apni CNIC par registered SIMs check karna legal hai, lekin kisi aur ka private SIM owner data nikalna safe ya legal nahi hota.”
This page provides general information only. It is not legal advice. For specific legal questions about SIM fraud, identity misuse, or cybercrime, consult a qualified legal professional or refer to official government guidance.
668 SIM Check for Overseas Pakistanis
Pakistani nationals living abroad often maintain an active CNIC and may have SIMs registered on it from before they left — or worry that connections have been added without their knowledge while they have been away.
The 668 sim check can potentially be used from abroad if your Pakistani SIM supports international roaming. If you have kept a Pakistani SIM active and it has roaming enabled on your current network, sending the SMS to 668 should work, though roaming rates will apply. The exact availability depends on your operator and their roaming agreements — confirm this directly with your network before trying.
For overseas users without an active Pakistani SIM, the cnic.sims.pk portal accessed via internet may be the more practical route, since it does not require a local connection.
A few specific cautions for overseas users using the 668 sim check or any alternative:
- Verify the cnic.sims.pk domain carefully — type it directly into your browser
- Avoid WhatsApp agents offering “overseas CNIC SIM check” services for a fee. These are overwhelmingly scams.
- If your 668 sim check result shows an unexpected count, contact the relevant Pakistani operator’s official international support line, or ask a trusted family member in Pakistan to visit the franchise on your behalf with proper written authorization
- NADRA and PTA continue updating their overseas digital services. Check their official portals for the most current options available to diaspora users.
The 668 sim check is a reasonable starting point even for overseas users — but final resolution for any unauthorized SIM always requires engagement with official operator channels in Pakistan.
Privacy Tips Before You Use 668 SIM Check
Using the 668 sim check through official channels is safe and straightforward. Keeping your data protected throughout the process just requires a few practical habits.
- Use only official channels. The 668 sim check via SMS and cnic.sims.pk accessed directly are the official methods. Third-party tools, apps, or agent services are not part of this system.
- Never share your OTP with anyone who calls, messages, or contacts you in connection with SIM verification.
- Do not upload photos of your CNIC to any website, email, or chat, unless you have independently verified the recipient is an official entity.
- Do not send your CNIC number to WhatsApp contacts offering to run the 668 sim check or disowning services on your behalf.
- Ignore pages promising “SIM owner details.” They have nothing to do with the 668 sim check and should be avoided entirely.
- Keep records. After using the 668 sim check, save the result. If you visit a franchise as a follow-up, keep the complaint reference.
- Visit operator franchises directly for corrections, disputes, or disowning requests — do not try to resolve these through online intermediaries.
“Apni CNIC information sirf official channels par use karein; unknown websites ya agents ko personal data na dein.”
How 668 SIM Check Helps Prevent SIM Misuse
SIM fraud creates real problems for real people in Pakistan. Fraudsters register SIMs on misused or stolen CNICs and use those connections for financial scams, OTP interception, fake account creation, and harassment. The CNIC holder often has no idea until an investigation points back to their identity.
To reduce CNIC and SIM misuse risk, follow our SIM fraud prevention guide.
Regular use of the 668 sim check is one of the most accessible tools available for catching this kind of problem early. Here is why it genuinely helps:
Early detection limits damage. An unauthorized SIM caught before it is used in a fraud scheme can be disowned cleanly and without complication. The same SIM discovered after a fraud event creates a far more difficult situation to explain and resolve.
Awareness of your SIM quota matters. If someone has used your CNIC to register SIMs up to or near PTA’s maximum, you may find yourself unable to get new SIMs registered. The 668 sim check tells you where your count stands.
It reduces reliance on unsafe alternatives. When users do not know about the 668 sim check or cnic.sims.pk, many turn to fake SIM databases — spreading CNIC data further and creating additional risk. Official methods eliminate the need for those workarounds.
It creates a culture of SIM ownership accountability. Periodic checking, even when nothing seems wrong, is the habit that makes problems visible before they escalate. The 668 sim check makes that habit easy to maintain.

- Avoid all unofficial SIM database websites — they are unsafe and often illegal
- Never share your CNIC or OTP with unknown people, websites, or social media agents
- For current details on the 668 sim check process and charges, always verify through PTA’s official website or your operator’s official support page
668 SIM Check FAQs
What is 668 sim check?
The 668 sim check is a Pakistani SMS-based service that lets CNIC holders find out how many mobile SIM connections are currently registered under their own CNIC. You send your 13-digit CNIC number (without dashes) as an SMS to 668, and you receive an operator-wise count in reply. The 668 sim check is a personal identity management tool — not a public database — and it is designed to help Pakistani users monitor their SIM registrations, spot unauthorized connections, and manage their mobile identity through official channels.
How can I use 668 sim check in Pakistan?
To use the 668 sim check, open your phone’s SMS app, type your CNIC number without dashes, and send it to 668. You will receive a reply with the count of SIMs registered on your CNIC across operators. Standard SMS charges may apply, and the exact process may change over time. Before relying on this guide as the definitive instruction, verify the current details directly from your mobile operator or an official PTA-related source.
Can I check SIMs registered on my CNIC through 668?
Yes. The 668 sim check is specifically designed for this. It returns an operator-wise count of SIM connections registered under your own CNIC. If the count in your 668 sim check response does not match the number of SIMs you know you own, the next step is visiting the relevant operator’s official franchise with your original CNIC to verify and, if needed, disown any unauthorized connections through the biometric verification process.
Does 668 sim check show owner name?
No. The 668 sim check only returns a count of SIMs registered on your CNIC. It does not reveal the owner name of any SIM, and it does not show names, addresses, call records, or private details about any person — yourself or others. The 668 sim check is strictly a count-based awareness tool for your own CNIC, not a personal identity search service.
Can I check another person’s SIM owner details through 668?
No. The 668 sim check is intended for use with your own CNIC only. It does not function as a tool to look up the owner of a random phone number. It will not return another person’s private details regardless of what number or CNIC you send. Attempting to access someone else’s personal mobile data through unauthorized means can create legal issues under Pakistani cybercrime and privacy laws.
What is the difference between 667 and 668?
667 is used to check the registration status of the specific SIM currently in your phone. The 668 sim check covers all SIM connections registered against your entire CNIC across all operators. Use 667 when you want to confirm one SIM is properly active. Use the 668 sim check when you want a full picture of every connection registered under your identity. Neither is designed for checking other people’s mobile details.
Is 668 sim check legal in Pakistan?
Yes. Using the 668 sim check through official channels to check SIMs registered on your own CNIC is fully legal and encouraged by Pakistan’s telecom regulatory framework. What falls outside legal boundaries is trying to access another person’s private SIM data, CNIC, address, or personal information through unofficial tools. This is covered under Pakistan’s PECA and related privacy provisions. The 668 sim check keeps you within legal boundaries as long as you use it for your own CNIC only.
Does 668 show exact SIM numbers?
Generally, no. The 668 sim check reply typically shows the count of SIMs per operator linked to your CNIC — not the specific mobile numbers. If you need to identify the exact numbers registered under your CNIC, visiting the relevant operator’s official franchise with your original CNIC is the appropriate step. The cnic.sims.pk portal may provide additional information in some cases.
Does cnic.sims.pk show SIM details?
The cnic.sims.pk portal provides a web-based alternative to the 668 sim check for CNIC-linked SIM checking. It typically shows an operator-wise SIM count and may offer options to initiate a disown request. Always access it by typing the domain directly into your browser — not through links shared on social media. Fake copies of this portal exist, so careful domain verification is important before entering any personal information.
What should I do if 668 sim check shows an unknown SIM on my CNIC?
Start by accounting for all your existing SIMs before assuming fraud. If the count from your 668 sim check still does not add up, identify which operator shows the unexpected number and visit that operator’s official franchise with your original CNIC. Request biometric verification, confirm which connections are registered, and if any are unauthorized, formally request disowning. Always get a complaint reference number. If the operator does not resolve the issue, escalate through PTA’s official consumer complaint channel.
Can I disown an unauthorized SIM online?
Some operators and the cnic.sims.pk portal offer online options to initiate a disown request. For straightforward cases, this may work. However, if a SIM was fraudulently registered, a visit to the operator’s official franchise with your original CNIC and biometric verification is usually required for full resolution. After using the 668 sim check to identify the issue, verify the current disowning process from your specific operator’s official support page before taking action.
Is there any fee for 668 sim check?
Standard SMS charges may apply when you send a message to 668. The exact amount depends on your operator and their current tariff. Some operators may offer the 668 sim check at no cost; others may apply a standard SMS rate. These charges can change, so confirm the current fee with your mobile operator before using the service rather than relying on any fixed amount mentioned in third-party guides.
Can overseas Pakistanis use 668 sim check?
Overseas Pakistanis can potentially use the 668 sim check if their Pakistani SIM supports international roaming, though roaming charges would apply. For users without an active roaming SIM, the cnic.sims.pk portal accessed via internet may be more practical. Verify the correct official domain carefully. If the 668 sim check or portal reveals an unexpected count, contact the relevant operator’s official international support or ask a trusted family member in Pakistan to visit the franchise on your behalf.
Is it safe to use online SIM database websites?
No. Websites claiming to offer SIM owner lookup by number, “fresh SIM data,” or CNIC search by phone number are not official, not legal under normal circumstances, and not safe to use. Many collect personal data from visitors, generate fabricated results, or operate as phishing tools. The 668 sim check and cnic.sims.pk already provide what CNIC holders legitimately need. There is no reason to use unofficial SIM database platforms.
Does checksimsownership.com.pk store my CNIC or mobile number?
No. checksimsownership.com.pk is an informational website that explains official SIM verification methods in Pakistan, including the 668 sim check. It does not operate a CNIC database, does not collect or store CNIC numbers, mobile numbers, OTPs, or identity documents, and does not provide private owner lookup services. Its purpose is to help Pakistani users understand safe, legal, and official methods for managing their CNIC-linked SIM registrations.
Use 668 SIM Check the Right Way
The 668 sim check gives every Pakistani CNIC holder a quick, official way to see what is registered under their name. Use it. Check occasionally. And if something in the result does not add up, take the right steps — visit the relevant operator franchise with your original CNIC, not a random website with a search box.
A few things to carry forward:
- Use the 668 sim check only with your own CNIC
- Rely on official channels — 668 via SMS or cnic.sims.pk accessed directly
- Avoid illegal SIM database websites entirely, regardless of how professional they appear
- Never share your CNIC number, OTP, or identity documents with unknown people or unverified platforms
- If the 668 sim check shows an unfamiliar SIM, visit the relevant operator franchise and request biometric verification and formal disowning if needed
- Keep a record of any complaint or action taken
Your mobile identity is your responsibility. The 668 sim check makes managing it straightforward — as long as you use the right tools and the right channels.
