What is a CNIC and Why is it Linked to Your SIM?
A CNIC (Computerized National Identity Card) is a government-issued identity document in Pakistan that every citizen must possess. When you buy a new SIM, the telecom operator registers it under your CNIC. The Pakistan Telecommunication Authority (PTA) mandates this rule to prevent illegal SIM usage, fraud, and criminal activities. But over time, many people have found multiple SIMs issued in their name without their knowledge.
This is why checking all SIM numbers linked to your CNIC regularly is highly recommended.
How to Check All SIM Numbers on ID Card Online
If you suspect unauthorized SIMs are registered under your CNIC or simply want to confirm the number of SIMs issued to your name, there are several convenient online methods to do this.
