SIM Check via CNIC
See how many mobile SIMs are registered against your CNIC using Pakistan Telecommunication Authority (PTA) services. This guide just explains the official methods — nothing is sent from this site.
Method 1 — SMS 668
- Open your messaging app.
- Send your CNIC number (no dashes) as an SMS to 668.
- You receive a reply listing the SIMs registered against your CNIC.
3520212345678Method 2 — Dial 668
Dial 668 on the SIM you own from any mobile across operators. Follow the IVR: the system identifies the SIM, then askes for the CNIC to check others.
668Method 3 — PTA website
The PTA runs a "SIM Information System" page where you enter your 13-digit CNIC and receive the count of SIMs. From its tools menu: SIM Information. You can also check if you previously owned a number via the postpaid/former numbers checker. These services exist to combat SIM fraud, so if you see SIMs you don't recognise, report them to PTA through the official channels.
Checking a number to buy (MNP)
Before buying a used number, check which network it belongs to. Send an SMS with the text MNP to 668 followed by the 11-digit mobile number (without "0").
