A software engineer from Karachi checked his CNIC on a Tuesday afternoon in October 2025 — purely out of curiosity after reading an article about SIM fraud. What he found stopped him cold. Seven SIM cards were registered on his CNIC. He personally owned two. Five were completely unknown to him.
He spent the next six days visiting four different operator franchises, filing two FIA complaints, and making repeated calls to PTA’s helpline. By the time all five unauthorized SIMs were blocked, two of them had already been used to register mobile wallet accounts that had received and transferred a combined Rs. 47,000 in funds of unknown origin.
The blocking process itself was straightforward. The damage came from the delay — six days of unauthorized SIMs remaining active after he first discovered them. If he had known the exact process for blocking unauthorized SIMs on a CNIC before he discovered the problem, he could have completed the entire process in a single afternoon.
This guide gives you that knowledge right now. Every step, every operator, every contact you need — so that if you ever discover unauthorized SIM registrations on your CNIC, you can act immediately and efficiently rather than spending days figuring out the process under stress.
Understanding Unauthorized SIM Registrations in Pakistan
An unauthorized SIM registration occurs when a SIM card is registered under your CNIC without your knowledge or consent. This can happen through several methods that PTA and law enforcement have documented across Pakistan.
The most common method is photocopy-based registration — a fraudster obtains a photocopy of your CNIC from any of the dozens of routine transactions where CNICs are collected, and presents it at a mobile franchise where verification controls are weak. Although biometric verification is mandatory for all SIM registrations, franchise compliance varies significantly across Pakistan’s tens of thousands of authorized retailers.
The second method involves stolen biometric data — compromised fingerprint scanners at fraudulent “verification camps” or fake mobile registration booths that capture your biometric data during an apparently legitimate interaction, then use it for SIM registration fraud later.
The third method is insider fraud — a current or former employee of a mobile operator franchise with system access who registers SIMs using stored CNIC information without performing live biometric verification.
Regardless of how the unauthorized registration occurred, your legal responsibility for activities on those SIMs begins the moment they are registered — and ends only when you formally report and block them through official channels.
Step 1 — Confirm Unauthorized SIMs Exist on Your CNIC
Before taking any action, confirm exactly which operators have unauthorized SIM registrations on your CNIC. This takes 30 seconds.
Send your CNIC to 668:
Open the SMS app on any phone on any network. Type your 13-digit CNIC number without dashes — for example 4210198765432. Send to 668. Within 30 seconds receive a reply showing the SIM count per operator.
Read the result carefully:
Write down how many SIM cards you personally own from each operator. Compare against the 668 result one operator at a time.
Example: If 668 shows Jazz: 3 but you only own 1 Jazz SIM — 2 unauthorized Jazz SIMs exist on your CNIC. If 668 shows Zong: 2 but you own no Zong SIMs — 2 unauthorized Zong SIMs exist. Any discrepancy, even a single extra SIM on any operator, requires immediate action.
If all numbers match your personal SIMs — your CNIC is clean. Recheck in three months.
Step 2 — Get the Actual Phone Numbers of Unauthorized SIMs
The 668 reply shows counts but not the actual phone numbers of unauthorized SIMs. To get the specific numbers — which you need for FIA complaints and for confirming blocking after the process is complete — visit the relevant operator’s service center.
Visit the service center of each operator showing unauthorized SIM counts. Bring your original CNIC. Request a “CNIC SIM Registration Printout” or “All SIMs on CNIC Report” at the counter.
After biometric verification the representative prints a complete list of every mobile number registered on your CNIC for their network — including activation dates, registration locations, and current status. Compare this list against your personal numbers to identify the specific unauthorized ones.
Keep this printed list. You will need the unauthorized numbers for Step 5 — FIA complaint filing — if fraud has already been committed.
Step 3 — Submit SIM Disowning Request at Each Operator
This is the official process for blocking unauthorized SIMs on your CNIC. It must be done in person at each operator’s service center. There is no online option, no phone option, and no WhatsApp option — PTA requires physical presence and biometric verification for all SIM Disowning requests.
At the counter use the exact phrase: “I want to submit a SIM Disowning Request.”
This specific phrase triggers the correct process. Franchise staff are trained to handle this request type. Using vague language like “I want to block a SIM” may lead to confusion with the process for blocking your own lost SIM rather than disowning an unauthorized one.
The complete SIM Disowning process at each operator:
Step 1: Present your original CNIC — not a photocopy, not a photo on your phone. Physical original mandatory.
Step 2: Complete biometric fingerprint verification at the counter. This confirms you are the legitimate CNIC holder and authorizes the disowning request.
Step 3: Specify which SIM or SIMs you want to disown. If you have the printed list from Step 2, provide the specific numbers. If you do not have the numbers, tell the representative the count — “There are 2 Jazz SIMs on my CNIC that I did not register. I want to disown all unauthorized registrations.”
Step 4: The representative submits the SIM Disowning request to PTA’s system. You should receive a reference number or confirmation SMS — save this for follow-up.
Step 5: Under PTA regulations the operator must process your SIM Disowning request and block the unauthorized SIM within 24 to 48 hours of receiving your verified request.
Operator-Specific Service Center Details
| Operator | Free Helpline | Service Hours | SIM Disowning Time |
|---|---|---|---|
| Jazz | 111 (from Jazz) | Service centers 9 AM – 8 PM | 24-48 hours |
| Zong | 310 (from Zong) | Service centers 9 AM – 8 PM | 24-48 hours |
| Telenor | 345 (from Telenor) | Service centers 9 AM – 8 PM | 24-48 hours |
| Ufone | 333 (from Ufone) | Service centers 9 AM – 8 PM | 24-48 hours |
Call the helpline before visiting to confirm the nearest service center location and whether they are open. Some smaller franchise locations may not handle SIM Disowning requests — always visit a full Customer Service Center rather than a small retail outlet for this process.
Step 4 — Confirm Blocking After 48 Hours
After submitting SIM Disowning requests at all relevant operators, wait 48 hours and then confirm the unauthorized SIMs have been blocked.
Send your CNIC to 668 again. The reply should now show SIM counts that match only your personal SIMs. If any operator still shows a higher count than your personal SIMs after 48 hours, the disowning request has not been processed correctly.
If this happens return to that operator’s service center immediately and ask for the status of your SIM Disowning request using the reference number you received. Escalate to the center manager if the representative cannot resolve it. Under PTA regulations operators face consequences for failing to process authorized disowning requests within the required timeframe.
Step 5 — File FIA Complaint If Fraud Was Committed
If the unauthorized SIMs on your CNIC were used for any criminal activity — mobile wallet fraud, banking OTP interception, loan applications, harassment campaigns, financial scams, or any other illegal activity — blocking the SIMs is not sufficient. You must file an FIA complaint to protect yourself legally and to enable law enforcement to identify and prosecute the perpetrators.
Filing online at complaint.fia.gov.pk:
Visit complaint.fia.gov.pk in any web browser. Select the appropriate complaint category — cybercrime, financial fraud, or harassment depending on what the unauthorized SIM was used for. Fill in the complaint form with your CNIC number, the unauthorized SIM numbers obtained in Step 2, the operator names, and a clear description of the fraudulent activity. Attach any evidence you have — screenshots of suspicious transactions, messages received from the unauthorized numbers, or bank alerts related to the fraud. Submit and save your complaint reference number.
Filing in person at FIA Cybercrime offices:
FIA Cybercrime Wing offices are located in all major Pakistani cities. In-person filing is recommended for serious cases involving significant financial fraud, as it allows you to present physical evidence and receive immediate case guidance from FIA officers.
What FIA can do that you cannot:
FIA has legal authority to subpoena complete subscriber records from any Pakistani mobile operator, access call records and transaction histories linked to any number under investigation, and trace the physical location and identity of the person who registered the unauthorized SIM. FIA has successfully prosecuted multiple unauthorized SIM registration fraud cases resulting in convictions in 2025 and 2026.
Step 6 — Ongoing Protection After Blocking
Blocking unauthorized SIMs resolves the immediate problem but does not eliminate the risk of future unauthorized registrations if your CNIC information remains compromised. Take these protective steps after completing the disowning process.
Change all mobile banking passwords and PINs immediately. If unauthorized SIMs were registered on your CNIC, your CNIC information is in the hands of fraudsters. Assume your mobile banking credentials may also be at risk and change them immediately — JazzCash, Easypaisa, bank mobile apps, and all associated email passwords.
Report to NADRA if the CNIC itself was compromised. If you believe your physical CNIC was used — not just a photocopy — call NADRA at 1800-1100 and report the potential compromise. NADRA can flag your CNIC for enhanced verification requirements on any future SIM registration attempts.
Check your CNIC every month for the next three months. After discovering unauthorized registrations, fraudsters sometimes attempt re-registration. Monthly checks for the first three months after an incident catch re-attempts quickly.
Write purposes on all future CNIC copies. Going forward, write the specific purpose diagonally across any CNIC photocopy you provide — for example “For employment verification — [company name] — [date].” This prevents the copy from being reused for unauthorized SIM registration.

Frequently Asked Questions
Q1: How do I block unauthorized SIMs on my CNIC in Pakistan?
First confirm unauthorized registrations by sending your CNIC to 668. Then visit the relevant operator’s service center with your original CNIC and say “I want to submit a SIM Disowning Request.” Complete biometric verification. The operator blocks the unauthorized SIM within 24 to 48 hours. Confirm by checking 668 again after 48 hours.
Q2: Can I block unauthorized SIMs on my CNIC online or over the phone?
No. PTA requires physical presence and biometric verification for all SIM Disowning requests. You must visit the operator’s service center in person with your original CNIC. No online portal, phone call, WhatsApp message, or app can process a SIM Disowning request — anyone claiming otherwise is misinforming you.
Q3: How long does it take to block an unauthorized SIM after I submit the request?
PTA regulations require operators to process and complete SIM Disowning requests within 24 to 48 hours of receiving your verified in-person request with original CNIC. If not completed within 48 hours return to the service center and escalate to the center manager.
Q4: Do I need to visit a separate service center for each operator?
Yes. Each operator only has access to their own subscriber records and can only process disowning requests for their own network SIMs. If unauthorized SIMs exist across three operators you must visit three separate service centers. Call each operator’s helpline first to confirm the nearest full service center location.
Q5: What happens if I do not block unauthorized SIMs discovered on my CNIC?
You remain legally responsible for all activities conducted through those SIMs under Pakistani law. This includes financial fraud, harassment, criminal communications, and loan applications. FIA investigations triggered by activities on those SIMs will initially focus on you as the CNIC holder. The longer you delay, the more liability accumulates.
Q6: Someone re-registered a SIM on my CNIC after I blocked the original unauthorized SIM. What do I do?
This indicates your CNIC information is actively being misused rather than being a one-time incident. File an enhanced FIA complaint immediately at complaint.fia.gov.pk specifying that re-registration has occurred after a previous disowning. Also report to NADRA at 1800-1100 to flag your CNIC for enhanced registration verification. Continue monthly CNIC checks via 668.
Q7: Can I get compensation for financial losses caused by unauthorized SIMs on my CNIC?
Compensation claims for financial fraud through unauthorized SIMs must be pursued through FIA complaints and potentially civil court proceedings depending on the nature of the fraud. Many mobile wallet operators and banks have fraud liability policies — contact your specific financial institution’s fraud department immediately after filing the FIA complaint to begin their internal recovery process.
Final Summary
Blocking unauthorized SIMs on your CNIC is a straightforward six-step process — confirm with SMS 668, get the actual numbers from the service center, submit SIM Disowning requests, change your banking credentials, file an FIA complaint if fraud occurred, and confirm blocking after 48 hours.
The process takes one afternoon when you know what to do. The damage from delaying can take months to resolve.
