Select your operator to see how to verify your SIM, confirm ownership and block numbers you don't recognise.

The same three rules apply to every operator

  1. Start with PTA. The 668 service shows how many SIMs are on your CNIC.
  2. Go in person. Ownership changes, blocking and duplicate SIMs require your original CNIC and biometric verification at an official outlet.
  3. Never share codes. No operator, PTA or NADRA official will ask for your OTP or ask you to verify a fingerprint on someone else's device.
