SIM Registration Check Guide
Check the SIMs registered on your CNIC and stay safe from fraud. Write your CNIC below — we will create the SMS text that you have to send to 668.
Note: This guide only explains the method. Verification happens on PTA official systems (SMS 668 and the PTA portal) — we do not give any live check or owner details here.
Step 1: Create SMS text from your CNIC
Example: 3520112345678 — no dashes or spaces.
SMS to send to 668
Copy this text and send it as SMS to 668. You will get the list of SIMs registered on your CNIC in reply. The operator charges for each SMS.
Method 1: Check by SMS (668)
- Type your CNIC number (13 digits, no dashes) on your mobile.
- Send an SMS to 668.
- You will get a reply shortly — it will have the list of all SIMs registered in your name (Jazz, Telenor, Zong, Ufone — all).
- If there is any unknown number in the list, get it blocked at once (see below).
Method 2: PTA SIM Information Portal
- Open the official portal: cnic.sims.pk (PTA SIM Information System).
- Enter your CNIC number and complete the verification.
- The portal will show the details of SIMs registered on your CNIC (a small charge applies per query).
- PTA official website: pta.gov.pk
What to do if you find an unknown SIM?
- First call that operator’s customer care helpline and request to block the SIM.
- If the operator does not help, file a complaint on the PTA helpline 0800-55055.
- Keep your CNIC and SIM ownership record safe.
Stay safe from fraud: Never give your CNIC, OTP or bank details to any unknown number. PTA or banks never ask for OTP on the phone. Report suspicious calls on the PTA helpline.
