Finding a SIM registered on your CNIC that you never bought is a frightening moment. So is realising your number, identity, or personal data has been used for a scam. The good news is that Pakistan has clear, official channels for both problems, and acting quickly can stop the damage and keep you on the right side of the law.
This guide walks you through exactly where to report a fraudulent SIM, who handles which kind of complaint, what evidence you need, and how to get an unauthorised number blocked. The most important thing to understand first is that two different authorities are involved depending on what went wrong.
Know Who Handles What: PTA vs FIA vs NCCIA
People often lump every telecom problem under “report it to PTA” or “report it to FIA,” but the responsibilities are split.
The Pakistan Telecommunication Authority (PTA) is the telecom regulator. It deals with the SIM side of things: how many SIMs are registered on your CNIC, unauthorised registrations, operator misconduct, and getting illegal SIMs blocked. If your complaint is about a SIM that should not exist or an operator that issued one improperly, PTA is your starting point.
The National Cyber Crime Investigation Agency (NCCIA) handles the crime side. If your number, data, or identity was used for financial fraud, blackmail, hacking, or impersonation, that is a cybercrime. NCCIA was set up under the Prevention of Electronic Crimes Act and took over cybercrime investigations from the FIA’s Cyber Crime Wing during 2025. So if you have been searching for “FIA cyber crime complaint,” the modern route now runs through NCCIA.
In short, PTA fixes the SIM, NCCIA pursues the criminal, and your bank protects your money. Serious cases usually need all three.
Before You Report: Confirm and Gather Evidence
A complaint moves faster when you arrive with proof rather than a vague worry. Take a little time to build your case first.
Start by confirming which SIMs are actually registered on your identity. Send your 13-digit CNIC number, without dashes, by SMS to 668, or check the official portal at cnic.sims.pk. You will get back a list of how many SIMs each operator has issued in your name. Compare it against the SIMs you genuinely own. Keeping an organised record through the check how many SIMs are registered on your CNIC guide makes the odd one out far easier to spot.
Once you have identified an unfamiliar number, collect the following:
- A screenshot of the 668 reply or the cnic.sims.pk result, with the date visible.
- The exact mobile number and the network operator shown beside it.
- Your CNIC details and a list of the SIMs you legitimately own.
- For any financial loss: transaction IDs, dates, amounts, and bank or wallet statements.
- Any related messages, call records, or emails from the fraudster.
If you are unsure who a suspicious number belongs to, you can verify it first using the SIM Owner Details checker so your complaint names the right operator and details.
How to Report and Block a Fraudulent SIM (PTA Route)
If the problem is an unauthorised SIM on your CNIC, follow this sequence to get it blocked and on the record.
1. Visit the right operator’s franchise. The 668 reply tells you which network issued the SIM. Go to that operator’s official franchise or customer service centre, whether Jazz, Zong, Telenor, Ufone, or SCO, carrying your original CNIC. Photocopies are not accepted for this.
2. Request a SIM disowning. Tell the representative you want to disown a number registered without your consent. You will complete a standard disowning form and give a live biometric thumb scan to prove your identity. Each operator must be handled separately, so if unknown SIMs sit across two networks, you visit both.
3. Keep the receipt and reference number. Hold on to every receipt and reference for at least six months. A disowned SIM is permanently blocked and cannot be reactivated by anyone afterward.
4. Re-check after 24 to 48 hours. Send your CNIC to 668 again to confirm the line has dropped off your record.
5. Escalate to PTA if the operator stalls. If the franchise does not act, file a complaint through the PTA portal at complaint.pta.gov.pk or call the helpline 0800-55055. PTA can press the operator for a forced deactivation. To keep an ongoing eye on your registrations afterward, the CNIC Tracker helps you monitor what is tied to your identity.
How to Report Data Misuse and Fraud (NCCIA / Cybercrime Route)
When your number or identity has been used to commit a crime, or money has been taken, the SIM block alone is not enough. You need a cybercrime complaint so investigators can pursue the offender and help with recovery.
1. Secure your accounts first. Before anything else, change passwords for your banking apps, email, and social media, and switch to app-based two-factor authentication where you can.
2. File with NCCIA. Submit your complaint online at complaint.nccia.gov.pk, or email it to the agency. You will need your name, CNIC, contact details, a clear description of what happened, and all the evidence you gathered. For guidance, the NCCIA helpline 1799 can explain the process, though a phone call alone does not register a formal complaint.
3. Expect a verification window. Under the current process, complaints are typically verified within about 14 days, after which an investigation officer has up to 90 days to work the case. Providing strong, well-organised evidence speeds this up.
4. Visit a Cybercrime Reporting Centre if needed. For serious financial fraud or threats, an in-person visit to your nearest reporting centre with printed copies of your evidence can help.
5. File a police FIR where the law requires it. If several unauthorised SIMs are linked to your CNIC, lodge an FIR citing the Prevention of Electronic Crimes Act (PECA) 2016. For a heavily misused CNIC, NADRA can also flag your identity and reissue your card.
A word of caution that protects you: accessing someone else’s SIM or CNIC data without authorisation is itself an offence under PECA 2016, carrying prison time and heavy fines. Always rely on official channels and verified tools, and never buy data from shady “SIM database” sites while trying to investigate your own case.
Don’t Forget Your Bank and Wallet
If any money moved, or even if you only suspect your CNIC was compromised, contact your bank and your mobile wallet provider straight away. Report the fraud, ask them to freeze accounts or reverse pending transfers, and request that they flag your profile. Banks coordinate with NCCIA on fraud recovery, so the sooner they know, the better your odds of getting funds back.
Why Reporting Quickly Matters
A fraudulent SIM is not a harmless clerical error. A number registered in your name can be used for scams, harassment, or worse, and because the line sits under your identity, you can be drawn into investigations for crimes you had nothing to do with. Reporting creates an official timeline that proves you flagged the problem and acted in good faith. That paper trail is often what keeps an innocent CNIC holder out of a long legal mess.
Regular checks turn this from a crisis into a routine. Sending your CNIC to 668 once a month takes under a minute, and pairing it with the SIM Tracker and a quick look at your CNIC information on record means an unfamiliar number rarely gets the chance to do real harm.
It depends on the issue. To block an unauthorised SIM on your CNIC, report to PTA at complaint.pta.gov.pk or call 0800-55055. If the SIM or your data was used for fraud or another crime, report that to NCCIA, which now handles cybercrime cases that the FIA Cyber Crime Wing used to manage.
Cybercrime investigations moved to the National Cyber Crime Investigation Agency (NCCIA) during 2025. If you find older references to the FIA Cyber Crime Wing, the current route for digital fraud and identity misuse is the NCCIA portal at complaint.nccia.gov.pk and helpline 1799.
Note the operator shown in your 668 reply, visit that operator’s franchise with your original CNIC, request a SIM disowning, complete the biometric verification, and keep the receipt. Re-check 668 after 24 to 48 hours to confirm the block, and escalate to PTA if the operator delays.
A dated screenshot of your 668 or cnic.sims.pk result, the unknown number and its operator, your CNIC details, and any transaction records, messages, or call logs tied to the fraud. The more organised your evidence, the faster your case moves.
Yes. Checking your registrations through 668 and the official portal, filing a PTA complaint, and submitting an NCCIA cybercrime complaint are all free. Be wary of any website or agent that charges a fee to “remove” SIMs or recover data.
Report it to NCCIA as a cybercrime, and immediately notify your bank and wallet provider to freeze accounts and attempt to reverse transfers. Keep all transaction evidence, since banks coordinate with investigators on recovery.
Final Thoughts
Reporting a fraudulent SIM or data misuse comes down to sending it to the right place: PTA to block the SIM, NCCIA to chase the crime, and your bank to guard your money. Confirm the problem with a quick 668 check, gather your evidence, and move through the steps without delay. The faster you report, the more you limit the loss and the stronger your record that the fraud was never your doing.
