Knowing how many SIM cards are registered on your CNIC is essential in Pakistan, especially since the PTA limits users to a maximum of five active SIMs per CNIC. If you’re unsure about your SIM usage or want to verify registered numbers, this guide will walk you through the process using both online and SMS methods.
Why You Should Check SIMs on Your CNIC
Many people forget how many SIMs they’ve activated over the years. An old forgotten number might still be active under your name, which can cause issues during new SIM registration, mobile number portability, or even legal situations. That’s why the Pakistan Telecommunication Authority (PTA) has provided a verification system to check SIMs linked to your CNIC.
PTA SIM Information System
PTA has developed a centralized SIM Information System to enhance user security, prevent identity misuse, and regulate mobile subscriptions. It allows any mobile user in Pakistan to quickly verify how many SIMs are registered on their CNIC using a web portal or SMS code.
Method 1: Check SIMs Online Using Your CNIC
If you have access to the internet, you can check your SIM details online by following these steps:
-
Visit the official PTA SIM information portal.
-
Enter your 13-digit CNIC number in the input field.
-
Complete the CAPTCHA by selecting “I’m not a robot.”
-
Click Submit.
-
You’ll see a table showing the number of active SIMs against your CNIC for each mobile network (Jazz, Zong, Ufone, Telenor, SCOM).
Tip: Use the online portal on a secure connection and avoid sharing your CNIC with untrusted platforms.
Method 2: Check SIMs via SMS (Without Internet)
If you don’t have internet access, don’t worry — you can still check using SMS:
-
Open the messaging app on your phone.
-
Type your 13-digit CNIC number (without dashes).
-
Send it to 668 (PTA’s SIM verification service).
-
You’ll receive a message showing the number of active SIMs on each mobile operator.
Note: Standard SMS charges may apply depending on your network provider.
SIM Limits Per CNIC in Pakistan (2025 Rules)
According to PTA regulations, each individual is allowed:
-
5 SIMs for voice/data services
-
3 SIMs for MBB (Mobile Broadband)
Trying to activate more SIMs than allowed will result in rejection unless old ones are deactivated.
