How to Check SIM Owner Details in Pakistan 2026
Worried that someone has registered a SIM on your CNIC without your knowledge? Checking your SIM owner details is the official way to see every mobile connection linked to your identity, and it takes under a minute. Under PTA rules, every SIM sold in Pakistan is tied to a CNIC through biometric verification, so a quick audit can protect you from fraud — a SIM registered in your name but used by a stranger could involve you in crime investigations. This guide explains the two official PTA-approved methods for checking your registered SIMs, plus the extra codes every subscriber should know, verified on 15 October 2026.
SIM Owner Details: The Official PTA Methods
PTA supports checking which SIMs are registered under your own CNIC only — there is no legal service that lets you search another person’s name, CNIC or address from their mobile number. Websites or apps claiming to offer that are not authorised by PTA and should be treated as scams. The two approved methods are: send your 13-digit CNIC number (no dashes) by SMS to 668, or visit cnic.sims.pk in a browser, enter your CNIC and solve the CAPTCHA. The SMS reply shows a network-wise count — how many SIMs you hold on Jazz, Zong, Telenor, Ufone and others — for roughly Rs 1 to Rs 2 plus tax, while the web portal is completely free and works worldwide, which makes it ideal for overseas Pakistanis managing family connections back home.
Verify a Specific SIM with MNP to 667
If you want the registration details for one particular SIM — for example, a secondhand connection you just bought — send the word MNP to 667 from that SIM itself. The reply shows the registered owner’s name, a partially masked CNIC and the activation date. This only works for the SIM physically in your phone; by design, it cannot look up a random third-party number, which prevents misuse. A related trick: send any number (or N followed by the number) to 76367 to identify its current operator, handy after mobile number portability transfers.
Biometric Verification Checks by Operator
Knowing your registered SIMs is only half the story — every active SIM must also be biometrically verified against your CNIC through NADRA. Each operator offers its own check: Jazz users can SMS their CNIC number to 6001, Telenor users send a blank SMS to 7751, Zong users send the letter V to 7911, and Ufone users dial *336# and pick option 1. Network-specific self-checks also exist — Jazz users can dial *321#, Telenor *345# and Ufone *333# to list that operator’s SIMs on their CNIC. PTA limits every citizen to a maximum of 8 SIMs per CNIC (5 voice plus 3 data-only), enforced through the SIM verification management system. For current network offers and package details, see our Telenor packages 2026 guide.
What to Do If an Unknown SIM Appears
If your CNIC SIM check shows more SIMs than you personally own, act immediately — someone may have registered a connection using a copy of your CNIC through lost documents, franchise fraud or forged paperwork. First, screenshot the 668 or portal result with the date. Then call the operator’s helpline to report it, and visit their franchise with your original CNIC for biometric “SIM disowning”. You can also lodge a complaint through the PTA complaint portal or the PTA RAABTA WhatsApp line at 0315-0055055. Repeat the check after a few days to confirm the unknown SIM has been removed. Accessing someone else’s identity information without consent is a punishable offence under Section 16 of the Prevention of Electronic Crimes Act 2016, so always stick to checking your own CNIC. If you are buying a new phone for these SIMs, our PTA mobile tax 2026 guide explains the tax you will pay when registering the device.

Step-by-Step Walkthrough
Learning how to check SIM owner details in Pakistan is straightforward through official channels — and you should only use those channels, because third-party “SIM databases” are illegal and often scams. The legitimate reasons to check include verifying SIMs registered on your CNIC and blocking unknown numbers.
How to check SIM owner name and SIMs on your CNIC
To check number of SIMs on CNIC, use the PTA’s official SIM information system: enter your CNIC number on the PTA website to see how many SIMs each operator has registered against it. If you find a SIM you did not buy, visit the operator’s service centre with your original CNIC to have it blocked. This check is free and every citizen should do it at least once a year.
SIM owner details by CNIC and the PTA system
There is no public legal way to get SIM owner details by CNIC for someone else’s number — that data is protected, and anyone selling it is breaking the law. The PTA SIM information system only shows counts per operator for your own CNIC. If you receive threatening calls, report them to the PTA complaint portal or the FIA cybercrime wing with the number, date and time rather than trying to trace the caller yourself.
