Why SIM Owner Details Are Important
Pakistani law holds the registered SIM owner fully responsible for all activities conducted through that mobile number —from financial transactions to potential cybercrimes.
Key Reasons SIM Owner Details Matter
Security & Fraud Prevention
Detect unknown SIMs issued under your CNIC before they’re used for financial scams, loan fraud, or identity theft. Regular monitoring helps you catch unauthorised registrations early, before criminals can exploit them for illegal activities.
Legal Compliance
PECA 2016 and PTA regulations bind you to any misuse—scams, harassment, threats, illegal activities—carried out from SIMs registered to your identity. Ignorance is not a legal defence if your registered SIM is used in criminal activity.
Privacy Protection
Regular 668 checks ensure criminals aren’t quietly running SIM farms or illegal operations under your stolen identity. Identity thieves often register multiple SIMs to conduct large-scale fraud operations.

Account Recovery
Banks, WhatsApp, social media platforms, and email services require proof of SIM ownership for account recovery and two-factor authentication. Without proper SIM ownership documentation, recovering hacked accounts becomes nearly impossible.
Family & Business Safety
Verify unknown numbers before sensitive transactions, communications, or business dealings to reduce fraud risk. This is especially important for businesses conducting financial transactions via mobile banking.
Official PTA Warning: The registered user is responsible for their SIMs. Periodic verification is not optional—it’s mandatory for your legal protection.
How to Check SIM Owner Details via PTA 668
Pakistan’s centralized SIM Information System (668) gives you instant access to every mobile number tied to your identity. This is the most authoritative and comprehensive method for verifying all SIMs registered under your CNIC.
How to Check SIMs on CNIC via SMS 668
To check how many SIMs are registered against your CNIC, send your CNIC to 668 via SMS.
Steps:
- Open the messaging app on your phone
- Type your 13-digit CNIC number (without dashes or spaces)
- Send it to 668
- You’ll receive an SMS showing the count of active SIMs per operator
Example response:
- Jazz: 2 SIMs
- Zong: 1 SIM
- Telenor: 1 SIM
- Ufone: 0 SIMs
This method is network-independent and works on any Pakistani SIM, giving you a quick snapshot of all SIMs linked to your identity.

Sim Check app To find the number
Download our Play Store app to find Mobile Number owner using CNIC or Using their Phone Number to get information about them.
How to Use the PTA SIM Information
You can also view SIMs on your CNIC via PTA’s online SIM Information System for more detailed information.
Steps:
- Visit the PTA SIM Information System at cnic.sims.pk (or via official PTA website at pta.gov.pk)
- Enter your CNIC number (or foreign ID/passport where supported)
- Complete the CAPTCHA verification
- Click Submit or Check
- A table appears showing all active SIMs registered against your CNIC, grouped by operator
The table displays:
- Complete mobile numbers
- Network operator for each SIM
- Registration status (active, blocked, expired)
- Activation dates
If you see any unknown numbers, you should visit that operator’s franchise or customer service center and have them blocked or disowned via biometric verification.
How to Check SIM Owner Details by Mobile Number (MNP to 667)
You can query a specific mobile number’s registered details using the standard MNP (Mobile Number Portability) SMS to 667.
How to Use 667 (MNP) for SIM Owner Details
Sending MNP to 667 shows the SIM owner’s registered name, CNIC, and original operator for that number.

- Send the SMS and wait a few seconds
- You’ll receive an SMS reply that typically includes:
- SIM owner’s registered name
- CNIC number used for registration
- Original operator (before any porting)
This is the standard, operator-agnostic way to check SIM owner details by number through official channels in Pakistan. Standard SMS charges may apply, and response formats can change, so confirm with your operator if you encounter errors.
