How to Check the Number of SIMs

NADRA Launches New Website with Maps, Online Verification for CNICs
To improve security and reduce illegal activities, the Pakistan Telecommunication Authority (PTA) introduced the SIM Information System. This system allows users to check how many SIM cards are registered against their CNIC and helps people identify unauthorized numbers linked to their identity.
Why Checking Registered SIMs Is Important
Many people do not know the exact number of SIM cards issued on their CNIC. Sometimes old SIMs remain active for years, while in other cases unauthorized SIMs may be registered without the owner’s knowledge.
Checking your registered SIMs regularly can help protect your identity and prevent misuse. If a SIM registered in your name is used in illegal activity, it can create serious legal problems for you.
PTA SIM Limit on One CNIC
PTA allows a maximum of five SIM cards on one CNIC. These SIMs can belong to different mobile operators such as Jazz, Zong, Ufone, or Telenor.
If you already have five active SIMs and want a new connection, you must first block or close an unused SIM before purchasing another one.

Understanding SIM Cloning
SIM cloning is an illegal process in which criminals copy the data of one SIM card onto another SIM. This allows another person to use the same mobile number on a different device.
SIM cloning is dangerous because criminals may use cloned SIMs for illegal calls, scams, or criminal activities while the original owner becomes responsible.
Signs of SIM Cloning
Some common signs of SIM cloning include:
- Calls or messages you never made
- Sudden network issues
- Unusual balance deductions
- Receiving OTPs without requesting them
If you suspect SIM cloning, contact your mobile operator immediately and block the SIM.

The biometric system helps users:
