PTA (Pakistan Telecommunication Authority) has introduced updated systems to help users check SIM data quickly, safely, and easily.

Why Checking SIM Data Matters in 2025
People often remain unaware that multiple SIM cards might be registered under their CNIC without permission. This can lead to serious issues, including:
- Misuse of your identity
- Illegal activities under your CNIC
- Unwanted SIMs linked to your name
- Fraud calls and scams
- Difficulty registering new SIMs
To prevent these risks, it is important to regularly verify your SIM data using PTA’s official systems.
1. How to Check SIM Ownership Details Through SMS (668 Service)
One of the easiest ways to check the owner of any SIM number is by using the PTA’s official SMS service.
How to Use It:
- Open your mobile’s messaging app.

This method works for Jazz, Zong, Ufone, Telenor, and SCOM.
2. How to Check All SIMs Registered on Your CNIC (2025 Updated PTA Tool)
PTA’s SIM Information System (SIS) allows you to see how many SIMs are registered under your CNIC. This is the most reliable and official method.
Steps:
- Visit the PTA SIM Information System website.
- Enter your CNIC number.
- Solve the captcha and click Verify.
You Will See:
- Network-wise list of SIMs

This method helps you identify suspicious or unknown SIMs linked to your identity.
3. How to Check CNIC-Linked SIMs Through SMS
If you do not have internet, you can still check the number of SIMs on your CNIC through SMS.
Method:
- Send your CNIC number (without dashes) to 668.
Example: 3520212345678 → 668

4. How to Identify Unknown Number Owner in Pakistan (2025 Update)
If you keep receiving calls from an unknown number, you can check ownership using:
✔ Method 1: SMS to 668
Simply send the unknown number to 668.
✔ Method 2: Contact Customer Helpline
| Network | Helpline |
|---|---|
| Jazz | 111 |
| Zong | 310 |
| Ufone | 333 |
| Telenor | 345 |
Network support teams cannot disclose private data, but they can confirm if the number is legally active.
✔ Method 3: PTA Complaint System
If a number is harassing you, file a complaint through the PTA Consumer Complaint Portal.
5. Check SIM Data Using Mobile Apps (2025 Updated Apps)
Telecom companies now offer apps that show SIM data for your own number. You cannot check someone else’s data through these apps, but you can verify:
- SIM registration
- CNIC details
- Biometric status
- Active services
Popular Apps:
- Jazz World
- My Zong
- Ufone App
- Telenor App
These apps are secure and PTA-approved.
6. How to Block Unknown or Illegal SIMs Registered Under Your CNIC
If you see a SIM registered under your CNIC that does not belong to you, you must immediately block it.
How to Block:
- Visit your network franchise (Jazz, Zong, Ufone, or Telenor).
- Bring your original CNIC.
- Request the representative to remove the unauthorized SIM.
- Complete biometric verification.
PTA allows a maximum of 5 SIMs per CNIC, so blocking extra SIMs helps keep your record clean.
7. Common Issues and Their Solutions
❗ SMS Not Sending to 668
Check your balance or network coverage.
❗ Wrong Name Showing on SIM
Visit the franchise and update biometrics.
❗ Unknown SIMs Listed on CNIC
Block immediately through the network franchise.
❗ Cannot Register New SIM

8. Is Checking SIM Data Legal in Pakistan?
Yes—but only through official PTA systems.
Using third-party apps or illegal websites to check someone’s personal data is not allowed and can be dangerous.
Avoid:
- Fake “SIM owner finder” apps
- Websites that claim to show CNIC details
- Tools that sell personal information
Always use 668 SMS, PTA’s official website, or network helplines only.
Conclusion
In 2025, checking SIM ownership and verifying CNIC-linked SIMs has become essential for protection against fraud and identity misuse. PTA has made the process easier with its SMS service, online system, and network support tools. Whether you want to identify unknown callers or confirm your own SIM data, following the official methods ensures your information stays secure.
