In Pakistan, your Computerized National Identity Card (CNIC) is linked with all SIM cards issued in your name. This regulation, enforced by the Pakistan Telecommunication Authority (PTA), helps prevent misuse of mobile connections. However, there is growing concern about unauthorized SIMs being registered under someone’s ID without consent. To prevent such situations, every citizen should periodically check the number of SIMs registered on their CNIC.
This comprehensive guide will walk you through:
How to check how many SIMs are on your ID card
How to trace SIM information with a phone number
How to use TrueCallID to identify unknown callers
Steps to block suspicious SIMs
And more…
Let’s begin by understanding the importance of this process.
Why It’s Important to Check SIMs Registered on Your CNIC
Many users are unaware that someone could use their CNIC to illegally register a SIM card. These SIMs could then be used for criminal activities, fraud, or anonymous harassment. If a SIM registered to your ID is involved in any such activity, you could face:
Legal investigation
Financial penalties
Arrest and charges, depending on the severity
By regularly checking how many SIMs are registered under your CNIC, you can:
Identify unauthorized SIMs
Take action to block unrecognized numbers
Maintain control over your digital identity
Avoid becoming a victim of fraud
How Many SIMs Can Be Registered on One CNIC?
According to PTA rules, a maximum of 5 SIMs per mobile network can be registered on one CNIC at a time. That means you can have:
5 Jazz SIMs
5 Zong SIMs
5 Telenor SIMs
5 Ufone SIMs
If more than five SIMs from one operator are registered, the system won’t allow new SIM activation unless you deactivate one first.
Step-by-Step Guide: How to Check the Number of SIMs on Your ID Online
Checking how many SIMs are registered on your CNIC is free and easy. Here’s how to do it:
Step 1: Visit the Official PTA SIM Information Website
Go to: https://cnic.sims.pk/
This is the official SIM information system managed by PTA, available 24/7 for all users in Pakistan.
Step 2: Enter Your CNIC
Input your 13-digit CNIC number without dashes or spaces.
Step 3: Confirm You’re Human
Check the CAPTCHA checkbox (“I am not a robot”) and submit.
Step 4: See the Results
The system will instantly display the total number of SIMs registered on your CNIC, categorized by network:
| Network | Total SIMs |
|---|---|
| Jazz | 2 |
| Zong | 1 |
| Telenor | 0 |
| Ufone | 1 |
You will now know how many SIMs are active under your ID, per telecom provider.
Can I See the Actual SIM Numbers Registered?
No. For privacy and security reasons, the PTA system does not show the actual mobile numbers associated with your CNIC. It only shows the count per mobile network.
If you need to find the numbers, you must:
Check your call records or saved contacts
Insert SIMs into your phone one by one
Use USSD operator codes to display the number
Contact customer support of the respective network
But if you have received a call from a number and want to know who it is, this is where TrueCallID comes in.

How to Find Out Your SIM Numbers
If you have lost track of which numbers are under your CNIC and want to retrieve the actual phone numbers, here’s what to do:

Telenor: *888#
Your number will be displayed on the screen.

Option 3: Call Customer Support
Call the respective helpline and verify your identity with CNIC, your mother’s name, or location. They will help you trace the number registered on your CNIC.
How to Block Unused or Unauthorized SIMs
Once you identify extra or unknown SIMs on your CNIC, it’s time to take action. Here’s how you can block or deactivate them:
Step-by-Step SIM Blocking Process:
Visit the nearest customer service center of the concerned network
