Pakistan's SIM Registration System

All Pakistani mobile SIM cards are registered to a CNIC under PTA regulations enforced since 2012. Every prepaid and postpaid SIM active in Pakistan — on Jazz, Telenor, Zong, Ufone, or SCO — is linked to the CNIC of the registered owner. The PTA maintains a central database of this registration data accessible to operators, law enforcement, and through official public-facing lookup tools.

How to Check How Many SIMs Are Registered Against Your CNIC

The PTA provides an official channel for CNIC holders to verify which SIM cards are registered in their name:

  • Send your 13-digit CNIC number via SMS to 668.
  • The reply lists all SIM numbers currently registered to that CNIC, along with the operator name for each.
  • The service is free. A Pakistani SIM card is required to send the SMS.

Alternatively, visit the PTA's Device Identification, Registration, and Blocking System (DIRBS) portal at dirbs.pta.gov.pk, which includes a CNIC-based SIM lookup function.

What to Do If Unrecognized SIMs Appear

  • Contact the relevant operator's customer care immediately: Jazz 111-222-111, Telenor 345, Zong 310, Ufone 333.
  • Request blocking and de-registration of the unauthorized SIM.
  • File a complaint with PTA at pta.gov.pk/complaints if the operator does not resolve it promptly.
  • File a report with the FIA Cybercrime Wing (nr3c.gov.pk) if financial fraud is suspected.

The CNIC-SIM Link and Privacy

Because Pakistani SIM cards are CNIC-linked, a phone number provided during online registration is a strong identity signal. Platforms that collect Pakistani mobile numbers as verification can, in principle, link that number to the CNIC holder through operator records. This is one reason users who want to separate online activity from real-world identity choose email-based verification (via temp mail) over SMS-based verification for services that do not legally require CNIC verification.

Frequently Asked Questions

Can someone else register a SIM in my name without my knowledge?

This has occurred through biometric data fraud and corrupt retailer channels. PTA's 668 SMS service exists specifically to detect this. Checking your registered SIM count regularly is a basic identity security practice for Pakistani mobile users.

Does checking my SIM details cost money?

The 668 SMS service charges standard SMS rates on some operators and is free on others. DIRBS web lookup is free. Check with your operator for current SMS rates to 668.
