Self Check: SIMs Linked to Your CNIC
This guide is for checking your own SIM registration information. It does not claim direct access to telecom databases and does not reveal another subscriber's private information.
Simple verification approach
Keep your valid CNIC information available for an official verification process.
Check the current PTA-supported SIM information method, including the commonly referenced 668 process or official SIM information portal.
Check whether the SIM registrations shown are known and expected by you.
If a SIM appears that you do not recognize, contact the relevant mobile operator or official authority for verification and correction.
SIM Registration Basics
SIM Registration
A SIM is registered through the operator's identity verification process. Registration connects the subscriber record with the required identity information.
CNIC Check
A self-check helps you review SIM registrations associated with your own CNIC and notice records that may require attention.
Biometric Verification
Biometric verification is used in SIM-related subscriber processes. Follow the operator's current requirements for verification or replacement.

If an Unknown SIM Appears on Your CNIC

Confirm the information using an official telecom or PTA-supported channel before assuming the record is fraudulent.

Ask the relevant mobile operator about the unfamiliar registration and the available correction, blocking or ownership procedure.
3. Protect your identity
Never share your CNIC number, OTP, biometric information or account credentials with an unknown person or untrusted website.
4. Escalate when needed
If an issue cannot be resolved through the operator, use the appropriate official complaint or regulatory channel.
