A guide to SIM checks in Pakistan: number formats, prefix-based network identification, and the official PTA services for verifying your own SIMs. Includes SIM owner details (official verification methods), CNIC SIM check, and all official PTA SIM check codes.
6 Ways to Check SIM in Pakistan
There are multiple ways to perform a SIM check in Pakistan. Use our online tool or one of the official PTA methods below.
Online Network Check
Use the lookup tool on this page to identify a Pakistani mobile number's format and likely original network by prefix, with an MNP note.
*668# PTA Code
Dial *668# from your mobile phone to receive an SMS listing all SIMs registered against your CNIC. Free PTA service across all operators.
cnic.sims.pk
Visit the official PTA SIM Information System portal. Enter your 13-digit CNIC to view all registered SIMs with operator details and activation dates.
Operator USSD Codes
Use per-operator USSD codes for your own SIM: *321# (Jazz), *345# (Telenor), *333# (Ufone), SMS CNIC to 310 (Zong), Call 321 (SCOM).
MNP to 667
Send MNP to 667 from the SIM in your hand. PTA confirms which network that SIM is currently registered on — useful after porting.
Operator Franchise
Visit your mobile operator's franchise or NADRA center with your original CNIC for in-person SIM verification and assistance.
What a SIM Check Reveals
Depending on the method you use, a SIM check can confirm the following about a Pakistani number:
- Number format and likely original network by prefix
- MNP awareness — a prefix may not match the current network
- How many SIMs are registered on your own CNIC (via 668)
- Official verification channels for your own records — *668#, cnic.sims.pk, MNP 667

Why You Should Check Your SIM Regularly
Regular SIM checks help protect your identity and prevent financial fraud. Here is why every Pakistani should run a SIM registration check monthly.
Detect Unauthorized SIMs
Fraudsters register SIMs on stolen CNICs. A quick SIM check reveals unauthorized activations before they're used for crime.
Financial Fraud Prevention
Criminals use unauthorized SIMs to access JazzCash and Easypaisa wallets. Regular SIM checks protect your mobile money.
Legal Protection
If a SIM on your CNIC is used for unlawful activity, you may face inquiries from authorities. Monthly SIM checks help you spot unauthorized registrations sooner and report them through official channels.
365-Day Window
PTA extended the SIM disowning window to 365 days. Unauthorized SIMs stay on your CNIC longer, making regular checks essential.
Expired CNIC Risk
4.9M SIMs face blocking over expired CNICs. Check your SIM registration status regularly to avoid service disruption.
Avoid Fake Apps
1,400+ fake SIM check apps contain malware. Use our web-based tool or official PTA channels instead of downloading unknown apps.
Important Safety Notice:PTA and NCCIA have blocked over 1,400 fake SIM check applications that steal personal information. Many "SIM check apps" distributed through SMS and WhatsApp links contain malware that steals banking credentials and CNIC data. Never install APK files from unknown sources.
Always use our web-based SIM check tool or official PTA channels — *668#, MNP to 667, or cnic.sims.pk. Unauthorized access to someone else's SIM information may violate PECA 2016 with penalties including up to 3 years imprisonment and fines up to Rs. 5 million (Section 16). Report security incidents to PKCERT.
