SIM Owner Details 2026 – Check All SIMs on Your CNIC Free
Find out how many SIMs are registered against your own CNIC using the two methods PTA itself provides: an SMS to 668, or the free online portal cnic.sims.pk. No third-party sites, no guesswork.
Most people run this check for one of two reasons: they want a new SIM and need to confirm they haven’t hit their limit yet, or they want to make sure no one has used their CNIC to issue a SIM without their knowledge.
A maximum of 8 SIMs can be registered on one CNIC 5 voice and 3 data. Checking your own record takes under 30 seconds.
What is meant by “SIM owner details”?
SIM owner details means checking how many SIMs are registered against any CNIC, and which mobile companies they belong to — or checking which CNIC a particular SIM is registered against. It’s also how you’d verify the authenticity of a newly bought SIM before activating it. In Pakistan, this ownership information is treated as confidential. You can check the SIMs registered against your own CNIC, but you cannot legally check another person’s SIM ownership details.
Every SIM card in Pakistan must be registered against a valid CNIC and verified through fingerprint biometric verification. PTA keeps a record of every SIM in its system, showing which CNIC it belongs to — a system introduced to reduce mobile-based fraud and crime.
PTA limits every CNIC to a maximum of 8 SIMs across all networks combined, so that one person’s identity can’t be used to issue dozens of connections for fraudulent purposes. If you try to get a new SIM and find you’ve already reached this limit, the first thing to do is check your registered SIMs to find out exactly why — you may be carrying old or unused connections you’d forgotten about, or the limit may have been reached without your knowledge.
The two PTA-approved methods
Officially, there are only two PTA-approved ways to check SIM owner details. Both require your own CNIC.
Check via SMS to 668
- Open the messaging app on your phone, on any mobile network.
- Type your 13-digit CNIC number, with no dashes.
- Send the text message to 668.
- Get an instant reply showing SIMs registered per network — Jazz, Zong, Telenor, Ufone.
Check via cnic.sims.pk
- Open your browser and visit cnic.sims.pk.
- Enter your 13-digit CNIC number in the given field.
- Complete the CAPTCHA verification shown on screen.
- View the full list of SIMs registered against your CNIC.
Two more genuine codes are worth knowing. Send “MNP” to 667 from the SIM in your phone to instantly see which CNIC that specific SIM is registered against. And every operator offers a biometric-verification check through its own short code:
| Operator | How to check biometric verification |
|---|---|
| Jazz | Send your CNIC number to 6001 |
| Telenor | Send a blank SMS to 7751 |
| Zong | Send the letter V to 7911 |
| Ufone | Dial *336*1# |
You cannot check another person’s SIM owner details.
There is no legal service that lets you search another person’s name, CNIC number, or home address through their mobile number. Any website or app claiming to do this is not authorized by PTA or any telecom company — treat it as unreliable at best.
PTA only supports checking the SIM ownership details registered under your own CNIC. That’s a completely different, and fully legal, service.
Found a SIM you don’t recognize on your CNIC?
If your 668 result or the web portal shows more SIMs than you actually use, don’t panic — but act quickly.
Save the evidence
Take a screenshot of the SMS reply or web portal result. Note the date and time.
Call your operator’s helpline
Explain that an unregistered SIM appears to be linked to your CNIC.
Visit the franchise center
Bring your original CNIC and formally request staff to block the unknown SIM.
File a complaint with PTA
If your operator doesn’t resolve it through their helpline or website.
Report to FIA Cybercrime Wing (NCCIA)
If you suspect the SIM is being used for fraud or illegal activity.
Act fast — an unauthorized SIM linked to your identity can be misused for scams or fraudulent loans that could later be traced back to your CNIC.
Common questions about SIM owner details
Why would you need to check SIMs on your CNIC?
- To confirm how many mobile connections are currently active in your name
- To find out that your CNIC hasn’t been misused by someone to get an unauthorized SIM issued
- To keep your telecom record clean before applying for a new SIM
- To prepare documents for banking, visa, or legal purposes
- To make sure old SIMs you no longer use are still not linked to your identity
Can I check someone else’s SIM ownership details using their phone number?
No. This is an illegal activity. Only the CNIC holder can check the SIMs registered under their own identity, through official PTA methods such as 668 or cnic.sims.pk.
How to check SIM registration owner name?
You cannot check the name of another person on a SIM using just their phone number. PTA does not provide this service to the public.
What should I do first if I lose my SIM card?
Immediately block your SIM by calling your operator’s helpline, so no one else can use your number for calls, SMS, or mobile banking apps like JazzCash or Easypaisa before you get a replacement.
How can I block or cancel a lost SIM?
Call your operator’s helpline from any other phone — Jazz: 111, Zong: 310, Telenor: 345, Ufone: 333. They’ll verify your identity using the CNIC details already registered on that SIM.
Check your own record — that’s the whole service.
Checking SIM owner details in Pakistan only means checking the SIMs registered under your own CNIC. PTA has made this process simple: send your 13-digit CNIC number to 668 or visit cnic.sims.pk for a free or nearly-free result, and it takes less than 30 seconds.
Avoid using websites that claim to reveal sim owner details by number. It’s a good habit to periodically check your own sim ownership details so you can stay safe from any serious identity misuse.
