In today’s digital era, every mobile SIM card is connected to a person’s identity. Whether you’re applying for a job, verifying your mobile records, or simply trying to secure your identity, knowing how many SIMs are registered under your CNIC is extremely important. In Pakistan, the Pakistan Telecommunication Authority (PTA) has made it easier to track SIM information using Sim Ownership.
This complete guide will help you understand how to check all SIM numbers on your ID card online, along with details on SIM ownership, SIM number tracking, and SIM registration verification using your CNIC (Computerized National Identity Card).
Why Checking SIM Numbers on CNIC is Important
Before we get into the process, let’s understand why it matters. Here are a few reasons:
Prevent fraud or misuse: Someone may use your CNIC to register SIMs without your permission.
Stay within PTA limits: PTA allows a maximum of 5 SIMs per CNIC. Exceeding the limit can block future SIM registration.
Protect your identity: If your CNIC is used illegally, you can face legal action.
Track unauthorized usage: Many people have no idea how many SIMs are under their CNIC until they face issues.
Keep your digital life secure: Many bank apps and services use your mobile number for verification.
