Every few months, Pakistanis discover SIMs registered on their name that they never bought — sometimes an old forgotten purchase, sometimes a retailer misusing their thumbprint, sometimes outright fraud. Checking takes one minute and it’s free. Here are the three official ways, fastest first.
Method 1 — 668 SMS (one minute)
Type your 13-digit CNIC number (no dashes, no spaces) and send it to 668. PTA replies with your SIM count broken down by operator — Jazz, Zong, Telenor, Ufone. A small service fee applies, so keep some balance. The reply arrives on the phone that sent the SMS.
Method 2 — PTA web portal (free, with record)
Open PTA’s SIM Information System portal (cnic.sims.pk), enter your CNIC, and you’ll see the same per-operator breakdown on screen — handy for keeping a dated screenshot as your record. The portal shows counts, not full numbers, by privacy design.
Method 3 — franchise biometric check (most thorough)
Take your original CNIC to any operator’s service center and ask for a biometric verification with your complete SIM record. This is the only method that shows number-level detail for your own CNIC — and the only one that can block unknown SIMs on the spot. Free, about ten minutes.
What to do with the result
Add up the per-operator counts and compare against the SIMs you actually own. Old forgotten SIMs are common and harmless — but get them closed anyway. Unknown SIMs are not harmless: visit a franchise with your original CNIC, have them blocked after biometric verification, and file complaints with PTA and the FIA Cyber Crime Wing if you suspect fraud. Re-run the 668 check a few days later to confirm.

How often should you check?
Every two to three months as routine hygiene — and immediately if your CNIC copy is ever lost, photocopied by strangers, or you suspect misuse. Put a recurring reminder on your phone; it’s one SMS.

Frequently asked questions
How can I check SIMs on my name for free? SMS your 13-digit CNIC (no dashes) to 668, use PTA’s SIM Information System portal, or visit any franchise with your original CNIC. All three are official; the franchise visit is the most thorough.
Can I check SIMs registered on someone else’s name? No — and you shouldn’t try. The 668 reply goes to the sender’s phone, so technically any CNIC can be queried, but looking up another person’s registration without consent is a privacy violation.
The 668 reply shows more SIMs than I own. What do I do? Treat unknown SIMs as identity misuse until proven otherwise. Get them blocked at any franchise with biometric verification, file complaints with PTA and FIA’s Cyber Crime Wing, and re-check after a few days.
Does the portal show full SIM numbers? No — counts per operator only. Full numbers are only visible through a biometric-verified franchise visit on your own CNIC.
