How to Check Registered SIMs on Your CNIC

Back in the early 2000s, mobile phones became widely accessible in Pakistan. As prices dropped and availability increased, more people started using cellular services. However, this rise also led to misuse, with unregistered SIMs being linked to illegal activities.

To address this, the Pakistan Telecommunication Authority (PTA) launched the SIM Information System in 2009. This system helps users verify the number of active SIMs registered against their CNIC, ensuring transparency and security.

Maximum SIMs Allowed on a CNIC

As per PTA regulations, an individual can register up to five SIM cards on a single CNIC. If you already have five and need another, you must first block an unused SIM to maintain the limit.

Checking Active SIMs on Your CNIC

If you are unsure about the number of SIMs issued under your CNIC, you can verify them using these methods:

Understanding SIM Cloning

SIM cloning involves duplicating a SIM card’s data, allowing unauthorized users to make calls under someone else’s identity. If you suspect fraudulent activity linked to your number, contact your mobile operator immediately to report and block unauthorized usage.

PTA Biometric Verification System (BVS)

The Biometric Verification System (BVS) is PTA’s initiative to enhance security by ensuring all SIM cards are verified. Through this system, you can:

• Obtain a duplicate SIM
• Buy or activate a new SIM
• Change SIM ownership
