Every SIM card is registered under a person’s CNIC (Computerized National Identity Card). The Pakistan Telecommunication Authority (PTA) has strict rules to make sure SIM ownership is verified to prevent misuse, fraud, and illegal activities.
Sometimes, people forget how many SIMs are registered on their CNIC. It’s important to check regularly, so you can block any unknown or unused SIMs in your name. This is where DB Center comes in. With the latest 2025 SIM database network, you can search SIM ownership details by CNIC or mobile number for all telecom companies in Pakistan, including Jazz, Zong, Ufone, Telenor, Warid, PTCL, Mobilink, and SCOM.
This guide will explain step-by-step how to check SIMs on CNIC with numbers, why it’s important, and how you can keep your SIM records safe.
Why You Should Check SIMs on Your CNIC
Checking SIMs linked to your CNIC is more than just keeping track of your numbers. It’s about protecting your identity, avoiding fraud, and ensuring your CNIC is not misused. Here are the main reasons:
Security – Unknown SIMs can be used for illegal activities in your name.
Privacy – Prevent strangers from having access to a SIM under your CNIC.
Control – Keep track of all the numbers you own.
Compliance – PTA limits the number of SIMs per CNIC (usually 5 per network).
How Many SIMs Can Be Registered on One CNIC?
According to PTA rules:
Maximum 5 SIMs can be registered under one CNIC for each network.
This means a total of up to 40 SIMs if you use all available networks (although most people use far fewer).
If you cross this limit, you will not be able to register new SIMs unless you block some old ones.
