SIM Database & Pak SIM Data: What They Really Are
Search for "SIM database" or "Pak SIM Data" and you will find dozens of websites promising a name, CNIC and address for any mobile number. This guide explains where that data comes from, why using it is risky, and the official way to check SIM information legally.
What is a "SIM database"?
Every SIM in Pakistan is biometrically registered against a CNIC. Those records belong to the mobile operator (Jazz, Zong, Telenor, Ufone) and are regulated by PTA. There is no public SIM database. The only official self-service system is the PTA SIM Information System, which only shows SIMs registered on your own CNIC.
Where Pak SIM Data sites get their results
- Leaked records — old data breaches copied and republished without consent.
- Fake or random results — made-up names generated to keep you clicking on ads.
- Data harvesting — the number or CNIC you type in is collected and sold or misused.
Why these sites are illegal
Under the Prevention of Electronic Crimes Act (PECA) 2016, obtaining, selling or sharing someone's identity information without authorisation is an offence. Read more in our guide: Is SIM owner detail legal?
The risks of using them
- Your own number and CNIC can be captured and used for scams or fake SIM registration.
- Wrong results can lead you to blame or harass an innocent person.
- Pages are often full of malware ads and fake "pay to unlock" offers.
The legal way to check SIM data
- 1Send your 13-digit CNIC number (without dashes) in an SMS to 668 to see how many SIMs are registered in your name.
- 2Or visit the official PTA SIM Information System at cnic.sims.pk.
- 3If you find a SIM you don't recognise, block the unknown SIM at your operator's franchise.
