Official Ways to Check SIM Ownership in Pakistan
Here are the currently available official and reliable methods to check mobile SIM registration and ownership:
1. Check SIM Ownership via SMS (PTA 668 Service)
The Pakistan Telecommunication Authority (PTA) provides the 668 service, which is the most trusted and popular method.
Steps:
- Open your phone’s SMS app.
- Type your CNIC number (without dashes).
- Send it to 668.
- Wait for a reply.
Result: You’ll receive an SMS showing the number of SIMs registered against your CNIC, broken down by mobile network (Jazz, Zong, Ufone, Telenor).
Note: This service doesn’t show the name of the SIM owner for someone else’s number. It shows only the SIMs registered under your CNIC.
2. Check SIM Ownership Online via PTA Website
The PTA also provides an official online portal:
- Visit Website: Sim Owner Details
- Enter your CNIC number
- Complete the captcha and submit.
Result: You’ll see a list of all SIMs currently registered on your CNIC, categorized by operator.
This online service is handy if you don’t want to rely on SMS, especially for smartphone users.
3. Check SIM Ownership by Mobile Network Customer Service
Each mobile network lets users verify number ownership through helplines and codes.

*444*6*1#to check ownership. - Zong: Dial 310 and request SIM ownership details after identity verification.
