Checking SIM owner details in Pakistan takes less than 60 seconds when you use the right method. Pakistan’s PTA (Pakistan Telecommunication Authority) provides three official, free, and completely legal ways to verify SIM ownership — no third-party app or website required.
This step-by-step guide walks you through each method so you can verify your registered SIMs in minutes.
Method 1 — Check All SIMs on Your CNIC via 668 SMS
Best for: Seeing a complete list of every SIM registered against your CNIC across all networks.
- Open your phone’s default SMS app
- Create a new message
- In the message body, type your full 13-digit CNIC number (no dashes, no spaces)
- Send the message to 668
- Within 10–30 seconds, you will receive a reply listing every SIM registered on your CNIC
What the reply shows: Network name, number of SIMs registered, and total count across all operators.
Cost: Free on all networks. No internet needed.
Method 2 — Check Who Owns Your Current SIM via 667
Best for: Quickly confirming the registered owner of the SIM currently in your phone.
- Open your SMS app
- Type: MNP (exactly as written, no extra characters)
- Send to: 667
- You will receive the registered owner name within seconds
Note: This only verifies the SIM currently inserted. To check other SIMs, swap the SIM and repeat.
Method 3 — Use the cnic.sims.pk Web Portal
Best for: A full detailed breakdown with registration dates and operator information, accessible from any device.
- Open any browser (Chrome, Firefox, Safari, etc.)
- Go to: cnic.sims.pk
- Enter your 13-digit CNIC number
- Complete the on-screen CAPTCHA
- Press ‘Submit’ or ‘Check’
- View the full list including network names, SIM numbers, and registration dates
