If you live in Pakistan, chances are you’ve received a random scam call or a strange SMS at least once. Most people don’t realize that sometimes the problem isn’t just the caller — it can be an old or unauthorized SIM still registered on their CNIC. That’s why SIM verification in Pakistan has become more important than ever.
The good news? The Pakistan Telecommunication Authority (PTA) has made it very easy to check how many SIM cards are registered on your name using your Computerized National Identity Card (CNIC). Whether you’re using Jazz, Zong, Telenor, or Ufone, you can track everything in just a few minutes — even without internet.
Let’s walk through it step by step, in simple, no-confusion English.
Why You Should Check SIMs on Your CNIC Regularly
Many people buy SIMs, stop using them, and completely forget about them. But those SIMs don’t disappear — they often stay linked to your CNIC.
Here’s why CNIC SIM tracking matters:
- Prevent scam calls and fraud
- Avoid identity misuse
- Keep your digital identity secure
- Stay within PTA SIM limits
- Protect yourself from legal or financial trouble
With strong telecom regulations in Pakistan, every SIM must go through a biometric verification system. Still, it’s your responsibility to keep track of what’s registered under your name.
SIM Registration Rules in Pakistan (Quick Overview)
According to the Pakistan Telecommunication Authority (PTA):
- One CNIC can have maximum 5 SIMs
- This rule applies across all telecom networks in Pakistan
- Networks include:

Once you reach this limit, you won’t be able to buy a new SIM unless you block one of your existing ones.
