The PTA SIM Information System is the official way to see how many SIMs are registered on your CNIC. It is run by the Pakistan Telecommunication Authority and works through the website cnic.sims.pk and the SMS short code 668. This complete guide explains how it works, how to use it step by step and what to do with the results.
What is the PTA SIM Information System?
After every SIM in Pakistan was linked to a CNIC with fingerprints, PTA created a central system so citizens could check their own SIM count. It does not show names or numbers of other people. It only tells you how many active SIMs are registered on the CNIC you enter, broken down by operator.
It is free, fast and available 24/7. It is also the safest option, because your data stays with PTA and is not passed to random third-party websites.
How to use the PTA SIM Information System website
- Open your browser and go to cnic.sims.pk. Make sure the address is spelled exactly like this.
- Type your 13-digit CNIC number without dashes.
- Enter the captcha code shown on the screen.
- Press Submit.
- The result shows the number of SIMs per operator, for example "Jazz: 2, Telenor: 1".
Using the PTA SIM Information System by SMS (668)
If you do not have internet, use SMS. Type your CNIC number without dashes and send it to 668. You get the same information as a reply. Learn more in 667 vs 668: what is the difference?
Understanding your results
| Result | What it means | What to do |
|---|---|---|
| Counts match the SIMs you use | Everything is fine | Check again in a few months |
| More SIMs than you use | Unknown or forgotten SIMs on your CNIC | Block them at the operator franchise |
| Fewer SIMs than you use | A SIM you use is in someone else's name | Transfer it to your CNIC |
| "No record found" | No active SIMs, or CNIC typed wrong | Re-check the number and try again |
Common problems and fixes
The website does not load
The site can be slow at busy times. Try again later, switch between Wi-Fi and mobile data, or use the 668 SMS method instead.
Captcha keeps failing
Captcha codes are case-sensitive. Refresh the code and type it carefully.
Result looks wrong
Recently closed or new SIMs may take a little time to update. Wait a day or two and check again. If it still looks wrong, contact your operator.

Beware of fake PTA SIM Information System sites
Scammers create look-alike websites with names similar to cnic.sims.pk. Some ask for your phone number, OTP or bank details. The real PTA SIM Information System only asks for your CNIC and a captcha. If a site asks for anything else, close it. Read more in Live tracker and SIM database sites: real or fake?
What the system cannot do
- It cannot show the owner of someone else's number.
- It does not list the actual phone numbers on your CNIC.
- It cannot block SIMs — you must visit your operator for that.
To see the exact numbers, visit a franchise with your CNIC. To block a SIM, follow our guide on blocking an unknown SIM on your CNIC.
Why you should check regularly
Any SIM registered on your CNIC is your legal responsibility. If someone uses it for fraud, police may contact you first. Checking every few months with the PTA SIM Information System takes less than a minute and can save you from serious trouble.
