Why Verify SIM Registration by Network?
Detect Unauthorized SIMs
Catch SIMs registered on your own CNIC without your knowledge across any network.
Identify a Number's Current Network
Prefixes show the original allocation; MNP 667 confirms the current network of the SIM in your hand.
Prevent Fraud
Fraudsters register SIMs on victims' CNICs across all networks. Regular checks of your own records help you stay protected.
Block Unauthorized SIMs
Each network has its own helpline for blocking unauthorized SIMs. Quick reference here.
Due to Mobile Number Portability (MNP), a number starting with a specific network prefix may now be active on a different operator. Prefix-based identification indicates the original network allocation and may not reflect the current carrier. Always verify current ownership through official PTA channels.
