Want to know how many SIMs are registered under your CNIC or who owns a number before buying it? Pakistan’s SIM Information System (SIS) makes it simple and secure.
With telecom fraud on the rise, being aware of the SIMs linked to your CNIC isn’t just helpful, it’s necessary. From using SIS 668 to PTA and PMD online tools, this guide will walk you through every method to verify numbers and owners quickly.
What Is A SIM Information System?
The SIM Information System is essentially a national database containing details of all SIMs registered in Pakistan. Managed by PTA (Pakistan Telecommunication Authority) and PMD (Pakistan Mobile Database), it helps maintain telecom security across the country.
This system allows users to:
- Verify SIM owner names and CNICs
- Track registration dates and operators
- Detect duplicate or fraudulent SIMs
For anyone buying a second-hand SIM or monitoring telecom activity, SIS is a must-know tool.
How To Check SIM Information With A Number
Checking who owns a number is easier than ever. Pakistanis typically use one of these methods:
- SMS via 668: Send the mobile number to 668 and receive the owner’s name, CNIC, and operator details instantly.
- USSD Code: Dial your network’s USSD SIM check code. It’s fast and works from any phone.
- Online Portals: Both PTA and PMD websites allow number verification for official checks.
Whether buying a used SIM or checking your own, these methods are reliable and widely used.
How Many SIMs Are Registered On Your CNIC
Ever wondered how many SIMs are linked to your CNIC? Here’s how you can check:
Use SMS 668 or the USSD CNIC SIM check code, and you’ll receive a list of all active SIMs under your ID.
Knowing this is critical because:
- You may discover old or inactive SIMs you forgot about
- Fraudsters sometimes register SIMs in someone else’s name
- You can take action to deactivate duplicates

Always resolve discrepancies promptly with your operator or PTA to stay secure.
PMD SIS Vs PTA SIM Information System
Here’s a simple comparison:
| Feature | PMD SIS | PTA SIS |
| Data Source | Telecom operators | National telecom regulator |
| Accuracy | Very high | Verified + audited |
| User Access | Via portals/USSD | Via portals/USSD/SMS |
The PTA system is official and highly reliable, ensuring accurate SIM information for all users. Whereas the PMD is often faster and provides real-time data, making quick verification more convenient.
Some users combine both systems when one provides incomplete info. This ensures accuracy in Pakistan’s fast-paced telecom environment.
