The SIM Information System is PTA’s official service that lets you check which SIM cards are registered on your CNIC in Pakistan. You can use it in two simple ways: send your 13-digit CNIC number (without dashes) by SMS to 668, or enter your CNIC on the free portal cnic.sims.pk.
Both methods show only the SIMs registered on your own CNIC. No website or service in Pakistan can legally show you another person’s SIM details from their phone number. This guide explains how the system works, how to read your results, and what to do if you spot a SIM you do not recognize.

What Is the SIM Information System?
The SIM Information System is a service run by the Pakistan Telecommunication Authority (PTA). It connects the SIM registration records of all mobile operators in Pakistan to your CNIC number.
Every SIM sold in Pakistan must be registered against a valid CNIC with biometric verification. The system collects these operator records in one place, and when you enter your CNIC, it shows a count of the SIMs registered in your name, broken down by operator.
PTA created this system to fight fraud. Criminals used to register SIMs on other people’s CNICs without their knowledge and use them for spam or scams. The system gives every citizen a simple way to audit their own record and catch misuse early.
The system only shows SIMs registered on the CNIC you enter. It does not reveal anyone’s name, address, or location. There is no legal tool in Pakistan that looks up another person’s SIM owner details from their phone number. Websites that claim this use stolen data or fake results, and using them can be a criminal offence.
This website is not linked with PTA, NADRA, or any government entity. We do not have access to any official database — we only guide you to PTA’s official channels. For a broader overview, see our guide to SIM information in Pakistan.
How to Check SIMs Registered on Your CNIC
Two official methods exist. Both take only a few minutes, and you only need your own CNIC number.
Method 1: SMS to 668
- Open the messaging app on your mobile phone.
- Type your 13-digit CNIC number without any dashes or spaces. For example, type 3520212345678 instead of 35202-1234567-8.
- Send this SMS to 668.
- You will receive a reply SMS with an operator-wise count of the SIMs registered on your CNIC.
The reply usually arrives within a few minutes; standard SMS rates may apply.
Method 2: cnic.sims.pk Portal (Free)
- Open your browser and go to cnic.sims.pk.
- Enter your 13-digit CNIC number in the given field, again without dashes.
- Complete the captcha shown on the page.
- Submit the form to see the SIMs registered on your CNIC.
The portal is completely free to use. You only need your CNIC number and a few seconds to complete the captcha.
Both methods give the same result, so use whichever is easier. To learn what your CNIC number itself reveals, see our CNIC information guide.
Understanding Your SIM Information Results
Your results show an operator-wise breakdown. This means you see a separate SIM count for each mobile operator, such as Jazz, Zong, Telenor, Ufone, and SCOM.
For example, your result might show: Jazz: 2, Zong: 1, Telenor: 0, Ufone: 1. This means two SIMs are registered on your CNIC with Jazz, one with Zong, none with Telenor, and one with Ufone.
The system shows counts, not full phone numbers, to protect your privacy. If the total matches the SIMs you own, your record is clean.
To verify, count every SIM in your name: your current phone, old or spare phones, tablets, USB devices, and any SIM you registered for a family member. Compare the total with the system’s count.
Results only cover your own CNIC. Never type your CNIC into untrusted third-party websites — stick to 668 and cnic.sims.pk. Read more safe SIM practices in our SIM information guide.
What to Do If You Find an Unknown SIM on Your CNIC
If the count is higher than the SIMs you own, act right away. An unknown SIM means someone may have used your identity, and any activity on that SIM is linked to your name.
Follow these steps:
- Visit your nearest franchise. Go to the customer service center of the operator in your result, with your original CNIC.
- Ask for the details. Staff can tell you the mobile number of the unknown SIM.
- Block or disown the SIM. Say you do not recognize this SIM and ask them to block it or remove it from your CNIC record. They will guide you through the process.
- File a PTA complaint if needed. If the franchise does not resolve it, or you believe your identity was stolen, file a complaint through PTA’s official Complaint Management System.
Do not ignore an unknown SIM. As long as it sits on your CNIC, you are responsible for it. Acting quickly protects your identity.
After the issue is resolved, check the system again in a few days to confirm the unknown SIM is gone.
