How to Check SIM Ownership & Block SIMs in Pakistan (PTA Guide 2025)
Every few weeks someone in Pakistan discovers a SIM registered on their CNIC that they never bought. Usually it's sloppy franchise practice; occasionally it's outright fraud. Either way, the fix is quick if you stick to the official channels — and everything below is the PTA flow, nothing third-party.
Check what's riding on your CNIC
- SMS 668. Type your 13-digit CNIC without dashes and send it to 668. It costs a couple of rupees plus tax, and the reply lists every active number against your CNIC.
- cnic.sims.pk. The web version gives the same table with operators and verification status, and lets you flag numbers from the same dashboard.
- MyPTA app. Register once with CNIC and mobile number, and you get SIM details, complaint filing and device status in one place — plus an alert if a new SIM is ever issued on your CNIC.
Run one of these every couple of months. Thirty seconds of digital hygiene.
Block what isn't yours
PTA caps SIMs at five per CNIC, and each one should trace back to your own biometric verification at the counter. If 668 shows a stranger's number:
- Visit that operator's franchise with your original CNIC — Jazz (111), Zong (310), Ufone (333) and Telenor (345) on helplines — and request immediate blocking of the unauthorised SIMs. Biometric re-verification happens at the counter.
- If the franchise stalls, escalate to PTA directly: toll-free 0800-55055, the online complaint portal, or [email protected] with your evidence attached.
Kill a stolen phone, not just the SIM
Because of DIRBS, every phone used in Pakistan has its IMEI registered, and a blocked IMEI dies on all networks — swapping SIMs does not help the thief.
- Dial
*#06#to read the IMEI. - File a block at dirbs.pta.gov.pk under lost or stolen devices, or through the PTA CMS app; a police complaint reference speeds the process up.
- Blocks normally take effect across all networks within a day or two, and the same app can unblock a recovered phone.
Habits that keep you clean
- Text MNP to 667 to confirm which network an unknown number belongs to before you trust it.
- Turn on the SIM PIN, so a stolen phone doesn't become a stolen identity.
- Never share your CNIC number, SIM serial or OTPs on a call — PTA and the operators simply don't ask.
- Skip every "SIM owner details" app on the stores; the unofficial ones are phishing tools, full stop.
It's a small guide about small chips, but a signal is never just a signal. In Gaza a working line is sometimes a family's only proof of life, and the engineered silence there is its own kind of violence — guard your connection, and pray for theirs.
Paperwork hygiene travels well, it turns out. Before you fly anywhere, our desk at HTG Travels checks your stack — passport validity, blank pages, visa file, dates — exactly the way you just checked your SIMs, so nothing surprises you at the airport counter at 3 a.m.
