Searches for "SIM information" often lead to sites promising a SIM owner's name, CNIC or address from just a phone number. In Pakistan that data is held by operators and NADRA and is protected — no legitimate public website can show it. Here is what you can check yourself, legally and for free.
What you can check
| Information | Official method |
|---|---|
| How many SIMs are on your CNIC | SMS CNIC to 668 or cnic.sims.pk |
| Your own number | Operator USSD code — see Own Number Check |
| Which network a number started on | Mobile Network Checker |
| Whether a phone is PTA approved | SMS IMEI to 8484 or DIRBS |
| The registered owner of your SIM | Visit the operator with your original CNIC |
What you cannot check (and shouldn't try)
Another person's name, CNIC, address or live location. Sites and social media pages selling "SIM data" are typically scams or are trading in leaked data. Using them can expose you to fraud and may break the law. If a number is harassing you, report it to the operator, to PTA's complaint portal, or to the FIA cybercrime wing.
A healthy SIM check routine
- Run the 668 check every few months.
- Compare the count with the SIMs you actually use.
- Block anything unfamiliar — see unknown SIM on CNIC.
- Never give your fingerprint or OTP to anyone outside an official outlet.
Frequently asked questions
Can I find SIM owner details by number?
No legitimate public service offers this. Owner data is private and only the operator or authorised agencies can access it.
Is 668 the official PTA service?
Yes, 668 is PTA's SMS shortcode for SIM information against a CNIC.
