Keeping your mobile connections secure starts with knowing which SIMs are registered against your CNIC. This simple guide explains why it matters, the legal context, and exactly how to check via official channels (online, SMS, and mobile apps). It also covers what to do if you spot unauthorized SIMs and how to stay safe from fraud.
Why verify SIMs on your CNIC?
- Security and privacy: Ensures strangers aren’t using SIMs registered to your identity.
- Fraud prevention: Reduces risk of scams, SIM misuse, or criminal activity tied to your CNIC.
- Legal compliance: Pakistan requires SIM registration against a valid CNIC and biometrics (BVS).

You have three reliable options:
- Online (SIM Information System)
- Sim owner Details
- Mobile operator apps (Jazz, Zong, Ufone, Telenor)
Check online (Web portal)
- Go to the Sim Owner Details SIM Information System
- Enter your CNIC number (without dashes) and complete any on-screen verification.
- Submit to view how many SIMs are registered against your CNIC, typically broken down by operator.
