In Pakistan, mobile phone usage grew rapidly in the early 2000s. While it made communication easier, unregistered SIM cards also became a tool for illegal activities. To deal with this, the Pakistan Telecommunication Authority (PTA) introduced systems that help every citizen check the number of SIMs linked with their CNIC.
Why It’s Important to Check SIMs on Your CNIC?
Every SIM registered under your CNIC is your responsibility. If there’s an unauthorized SIM linked to your ID, it can be misused for fraud, scams, or even criminal activities. Checking active SIMs ensures:
- Your identity remains safe
- No one misuses your CNIC
- You avoid legal complications
PTA SIM Information System
In 2009, PTA launched the SIM Information System. This digital platform lets users verify how many SIM cards are active under their CNIC. It’s a quick and reliable way to stay in control of your mobile connections.
SIM Registration Limits
PTA allows a maximum of five SIM cards per CNIC. If you already have five active SIMs and want another, you’ll need to block an existing one before applying.
How to Check Active SIMs Registered on CNIC
There are two official ways to check:
1. Through PTA SIM Information Website
- Visit the PTA SIM Information website.
- Enter your CNIC number.
- Complete the captcha.
- A detailed list of active SIMs by operator will appear.
2. By Sending SMS to 668
- Send your CNIC number (without dashes) to 668.
- You’ll receive a reply with the count of SIMs registered with each operator.
- Cost: PKR 2 + tax per SMS.
If you find any suspicious SIMs, immediately contact the operator or visit their franchise.
Consequences of Having Unknown SIMs on Your CNIC
- Someone can use your ID for criminal activities.
- You may face investigation or fines.
- Your personal data can be at risk.
That’s why regular checks are necessary.
Beware of SIM Cloning
SIM cloning happens when criminals duplicate your SIM card. They can make calls or use data in your name. If you receive complaints about calls you never made, report it to your operator right away and ask for the cloned SIM to be blocked.
PTA’s Biometric Verification System (BVS)
To improve security, PTA introduced biometric verification for:
- Buying or activating new SIMs
- Transferring SIM ownership
- Re-verifying old SIMs
- Handling number portability issues
This system ensures no SIM can be issued without your fingerprint verification.
How to Check SIM Ownership Online Using CNIC
If you want to know who owns a particular SIM, you can check it online:
- Visit the PTA SIM Information portal.
- Enter the CNIC number.
- Complete captcha verification.
- Instantly view details like registered SIMs, operator, and CNIC holder’s name.
How to Block a SIM Registered Against Your CNIC
If you notice a SIM you didn’t buy:
- Visit the customer service center of the respective operator.
- Provide your original CNIC.
- Fill out the deactivation form.
- The SIM will be blocked immediately.
How to Protect Your CNIC from Misuse
- Never share CNIC copies with strangers.
- Put a cross mark (X) on CNIC photocopies before giving them to shops.
