How to Check How Many SIMs Are Registered on Your CNIC in Pakistan (2026)

Many people in Pakistan want to know how many SIM cards are registered on their CNIC to avoid misuse of their identity. The Pakistan Telecommunication Authority (PTA) provides simple official methods to check this information.

Checking your registered SIMs is important because if someone uses a SIM issued on your CNIC for illegal activities, you may face legal problems.

Below are the official and safe ways to check SIMs registered on your CNIC.

1️⃣ Check SIMs via SMS (Fastest Method)

This is the easiest and most popular method in Pakistan.

Steps

1. Open the SMS / Messages app on your phone
2. Type your 13-digit CNIC number (without dashes)
3. Send the message to 668
4. Wait a few seconds for a reply

You will receive an SMS showing how many SIMs are registered under your CNIC on each mobile network (Jazz, Zong, Telenor, Ufone).

💰 Charges: Around Rs. 2 + tax per SMS.

2️⃣ Check SIMs Online Through the PTA Website

You can also check your SIMs using the official online system.

Steps

1. Open your browser
2. Go to the PTA SIM Information System website
3. Enter your 13-digit CNIC number (without dashes)

3️⃣ Maximum SIMs Allowed on One CNIC

According to PTA rules:

• Maximum SIMs allowed on one CNIC = 5

If you already have five SIMs registered, you cannot activate a new SIM until one is blocked or removed.
