Your CNIC (Computerized National Identity Card) is the unique identifier used to register every mobile SIM in Pakistan. So you need to check SIM owner details. If someone gets hold of your CNIC — even temporarily — they could register SIMs in your name without your knowledge.
Checking how many SIMs are registered on your CNIC is one of the most important digital security steps every Pakistani citizen should take regularly. Here’s how to do it in under 30 seconds.
Check All SIMs on CNIC via 668
- Pick up your mobile phone — any network works
- Open the SMS/Messages app
- Type your full 13-digit CNIC number (example: 3520112345678)
- Do not add dashes or spaces
- Send the SMS to: 668
- You’ll receive a response within 10-30 seconds listing all SIMs registered on your CNIC across all networks
What the 668 Reply Looks Like
The reply will show something similar to:
“Your CNIC 3520112345678 has 3 SIM(s) registered: Jazz – 2, Telenor – 1. For details visit cnic.sims.pk”
If the reply says 0 SIMs, either you have no registered SIMs or there’s an issue with the CNIC number you entered.
SIM Limit Per CNIC in Pakistan
- Maximum SIMs per operator: 5
- Maximum total SIMs across all operators: 25
- If you reach the limit on one operator, DIRBS will automatically block new activations on that network
- To register a new SIM when at the limit, you must first have an existing SIM deregistered
What to Do If You Find Unauthorized SIMs
- Note the network name and count from the 668 reply
- Visit cnic.sims.pk for the full detailed list with SIM numbers
- Visit the concerned network’s nearest franchise with your original CNIC
- Request immediate blocking and de-registration of unauthorized SIMs
- File a complaint at complaint.pta.gov.pk or call PTA helpline 0800-55055
