SIM Verification 2026: Check Registered SIMs on Your CNIC
Every mobile SIM in Pakistan must be registered against an approved identity document through biometric verification, and the SIM limit is enforced per CNIC. A quick SIM verification check is one of the most important digital security habits you can build: if someone registers a SIM on your CNIC without your knowledge, it can be used for fraud or unlawful activity traced back to you. In 2026, the PTA offers free and nearly-free official ways to see every SIM registered on your own CNIC. This guide explains each method step by step.
SIM Verification by SMS: Send Your CNIC to 668
The fastest official SIM verification method needs no internet. Open the messaging app on any phone and any network, type your 13-digit CNIC number without dashes or spaces, and send it to 668. Within seconds you receive a reply showing how many SIMs are registered on your CNIC, broken down by operator: Jazz, Zong, Telenor, Ufone and SCO. The message costs around Rs1 to Rs2 deducted from your balance.
Reading the reply is simple: count every SIM you personally own and use. If the 668 result shows more SIMs than you registered yourself, even one extra SIM is a serious security issue that you should act on immediately. Alternatively, dial *668# from your phone’s dialer on any Pakistani network and you will receive the same operator-wise breakdown by SMS, free of charge.
Check Online at cnic.sims.pk
The PTA’s SIM Information System at cnic.sims.pk offers free online SIM verification that works worldwide, which is especially useful for overseas Pakistanis. Enter your 13-digit CNIC number, complete the on-screen CAPTCHA, and submit to view the full list of SIMs registered against your CNIC, including the network-wise breakdown and registration dates, with an option to save or print the result.
Two related codes are worth knowing. Sending the text MNP to 667 from the SIM in your hand shows which CNIC that specific SIM is registered against, including the registered name and often a partly masked CNIC number. Sending a number to 76367 identifies its current operator, which is handy after mobile number portability. For checking your own identity record behind these SIMs, see our CNIC verification guide.
Biometric Verification Status by Operator
Every active SIM must be biometrically verified against your CNIC through NADRA, and each operator offers its own short code to confirm this status. Jazz customers send their CNIC number to 6001, Telenor customers send a blank SMS to 7751, Zong customers send the letter V to 7911, and Ufone customers dial *336# and follow the menu. Running this check confirms that your SIM’s biometric record is properly linked.
The Supreme Court enforced SIM limit allows a maximum of 8 SIMs per CNIC, split as 5 voice and 3 data-only SIMs across all operators, through the SIM verification management system. If you reach the limit and need a new connection, an existing SIM must first be deregistered. The same CNIC underpins other identity documents too; see our passport tracking guide if you are applying for travel papers. This cap exists to curb fraud and identity misuse.
What to Do About Unknown SIMs on Your CNIC
If your SIM verification reveals a number you do not recognize, act quickly. First, take a screenshot of the 668 reply or the cnic.sims.pk result with the date. Then call the operator’s helpline for the network showing the unknown SIM, and visit the nearest franchise with your original CNIC to request immediate blocking and biometric SIM disowning. You can also file a complaint with the PTA at its helpline 0800-55055 or through the PTA complaint portal and CMS app.
Remember the legal boundary: there is no legal service that lets you search another person’s name, CNIC or address through their mobile number. Any website claiming to do this is unauthorized. Under Section 16 of the Prevention of Electronic Crimes Act 2016, accessing someone else’s personal identity information without consent is a punishable offense. PTA only supports checking the SIMs registered under your own CNIC. Independent explainers such as this official-methods overview and this CNIC SIM check guide describe the same PTA-approved methods.
