667 vs 668 in Pakistan: What Each Code Does
Use the code that matches the task
Start with the question you need answered: all-network count against your identity, or information about the SIM you are currently using.
668 for the CNIC audit
Send the 13 CNIC digits without dashes to 668. Charges and response formatting can change, so keep enough balance and verify official guidance.
667 for the SIM in hand
The 667 route applies to the connection from which the request is sent. It is not an unrestricted lookup for any third-party number.
Official sources
For an up-to-date self-check, use PTA’s SIM Information System. For account-specific questions, use the official website, app, helpline or authorized service centre of your operator.
