SIM Check

Check SIMs Registered on Your CNIC

Find out how many SIMs are registered on your CNIC through PTA’s official channels. Enter your CNIC once and we will set up the SMS or the PTA website for you.

CNIC SIM check

Official PTA methods: SMS to 668 or cnic.sims.pk

Enter all 13 digits. Dashes are optional.

Send SMS to 668

Your CNIC stays on your device. This page does not send, store or log the number you type. The SMS goes from your phone straight to PTA, and the website check happens on PTA’s own site.

The 668 SMS carries a small charge set by your operator. The SMS button works on mobile phones; on a computer, use the PTA website button.

Two official ways to check SIMs on your CNIC

The Pakistan Telecommunication Authority (PTA) runs the SIM Information System, the only official record of which SIMs are registered against a CNIC. You can reach it in two ways, and the tool above sets up either one for you.

1. SMS to 668

Type your 13-digit CNIC number without dashes or spaces and send it to 668 from any network. PTA replies with the number of SIMs registered on your CNIC, split by operator. Your operator charges a small fee for this SMS.

2. The PTA website, cnic.sims.pk

Open cnic.sims.pk, enter your CNIC number, complete the captcha and submit. The page shows the same operator-wise count, free of charge.

How many SIMs can one CNIC have?

PTA allows up to five mobile SIMs on one CNIC across all networks. If you already have five and want a new connection, you need to block one of the existing SIMs first.

Found a SIM you do not recognise?

An extra SIM on your CNIC could be used for fraud in your name, so act on it quickly:

  1. Note which network the unknown SIM is on from the 668 reply or the PTA website.
  2. Visit that operator’s franchise or customer service centre with your original CNIC.
  3. Complete biometric verification and ask them to block or deactivate the SIMs you do not use.
  4. Run the 668 check again after a few days to confirm the count has dropped.

Check whose name your current SIM is on

To confirm the SIM in your phone is registered in your own name, send MNP to 667 from that SIM. This only works for the SIM you are sending from.

Avoid SIM owner lookup sites

Websites, apps and WhatsApp agents that promise to show the owner name, address or CNIC behind any number are not connected to PTA. Many show wrong information, some collect the CNIC and numbers people type in, and using leaked personal data is illegal. Stick to 668 and cnic.sims.pk for anything to do with your own SIMs.
