Understanding the Risk

What Are "Unauthorized SIMs"
and Why They're Dangerous

"Unauthorized SIMs" are mobile numbers issued on your CNIC that you never bought or no longer use, but still appear as active in PTA's SIM Information System.

🎭

Fraud and Scams

Fake prize schemes, loan scams, or phishing messages where legal trace‑back points to your CNIC.

🔐

OTP Misuse

Fraudsters can link unauthorized SIMs to bank accounts, wallets or social media, intercepting OTPs and taking over accounts.

⚖️

Legal Risk

PTA and operators treat "your SIMs" as your responsibility; if a number on your CNIC is involved in crime, you may get inquiries or legal notices.

PTA's Recommendation: PTA has repeatedly asked users to check and remove extra SIMs from their CNIC using the official 668 SIM Information System.

Step-by-Step Guide

How to Check and Block
Unauthorized SIMs

Check How Many SIMs Are on Your CNIC

You must first see how many SIMs each operator has issued on your CNIC.

A Online via cnic.sims.pk: Open a browser and go to https://cnic.sims.pk, enter your 13‑digit CNIC without dashes, complete the CAPTCHA and submit. You'll see a table showing the count of active SIMs per operator (Jazz, Zong, Telenor, Ufone, etc.).

B By SMS 668: Open the SMS app on any SIM, type your 13‑digit CNIC (no dashes), send it to 668. PTA's 668 system replies with the number of SIMs per operator on your CNIC.

PTA's Purpose: PTA states that 668 is designed so mobile users can check how many SIMs are issued on their CNIC and then request operators to remove extra ones where there is any mismatch.

Compare Counts With Your Actual SIMs

Make a simple comparison to identify unauthorized SIMs.

1 List the SIMs you actually use (Jazz/Zong/Telenor/Ufone)

2 Compare with PTA counts per operator

Example: You use: 2 Jazz, 1 Zong, 1 Telenor, 0 Ufone.
PTA shows: Jazz 4, Zong 1, Telenor 1, Ufone 0.

In this case, 2 extra Jazz SIMs exist on your CNIC that you never bought (or forgot to disown). These are unauthorized/extra SIMs and should be removed.

Disown or Block Unauthorized SIMs (Physical Franchise Process)

There is no fully online system to permanently remove all extra SIMs from your CNIC—PTA and the operators require biometric disowning at franchises.

1 Note which operator has extra SIMs (Jazz, Zong, Telenor, Ufone)

2 Visit that operator's Customer Service Center / Franchise with your original CNIC

3 Tell them you want to disown / block extra SIMs issued on your CNIC and show the 668 / cnic.sims.pk result

4 They will verify your identity via CNIC + biometric thumb verification under PTA's MBVS system

5 They will bring up the list of SIMs tied to your CNIC in their system and ask you to confirm which numbers are yours and which you want to disown

6 You sign the disowning request; for SIMs with less than 6 months retention, a disowning fee can apply unless they were clearly issued illegally without your consent

7 Operator sends notices to users of disowned SIMs and, if not regularized, blocks those numbers after a grace period (often around 15 days)

PTA's Process: After you disown extra SIMs, the users of those SIMs are asked to re‑register them on their own CNICs or face blocking.

After Disowning – Verify That SIMs Are Removed

Confirm that the unauthorized SIMs have been successfully removed from your CNIC.

1 Wait for the operator's processing and grace period (often 10–15 days)

2 Then re‑check via https://cnic.sims.pk or SMS your CNIC again to 668

3 Confirm that the operator SIM count has gone down (e.g. Jazz from 4 → 2, etc.)

4 If counts do not change after a reasonable time, file a PTA complaint (with your franchise receipts attached) so PTA can enforce the removal of irregular SIMs from your CNIC

Understanding the Difference

Difference Between Block, Disown
and Lost-SIM Blocking

Block (Lost/Stolen SIM)

You ask the operator to temporarily or permanently block a specific SIM number you own (e.g. if you lost your phone). It may still remain counted against your CNIC until you formally disown or change ownership.

Disown

You declare "I no longer own this number; remove it from my CNIC." After biometric disowning and grace period, the SIM is removed from your CNIC record in PTA's system.

Online PTA Complaint Blocking

You can file a PTA complaint (e.g. for stolen SIM or device) via the PTA complaint portal, but final removal from CNIC still depends on operator processing and disowning rules.

Key Point: For true cleanup of "extra SIMs on my CNIC", disowning at the operator's franchise with biometric verification is the key step.

Special Case

Overseas Pakistanis

PTA has an online facility for overseas Pakistanis to regularize or block extra SIMs on their CNIC without physically visiting franchises in Pakistan.

Overseas SIM Portal

They can use the dedicated PTA overseas SIM portal and provide passport/CNIC details to request blocking/regularization remotely.

If you live abroad and see unauthorized SIMs on your CNIC, use PTA's overseas page instead of waiting until your next visit to Pakistan.

Prevention

Best Practices to Prevent
Future Unauthorized SIMs

🛡️

Protect Your CNIC

Avoid giving clear CNIC photocopies to untrusted people; write "Only for [purpose] – Not for SIM issuance" across copies.

📅

Check 668 Regularly

Run an SMS check every few months so new illegal SIMs are caught early.

🚫

Never Leave CNIC with Shopkeepers

PTA has previously warned that CNIC copies left with retailers can be misused for illegal SIM issuance.

👆

Always Do Biometric at Authorized Points

New SIMs, duplicate SIMs, and ownership changes must be done on PTA‑approved BVS devices at official customer service centers, franchises or verified BVS retailers.

Frequently Asked

FAQs – Checking & Blocking
Unauthorized SIMs

Q1. How do I know if there are unauthorized SIMs on my CNIC?

Use https://cnic.sims.pk or SMS your CNIC to 668 to see how many SIMs each operator has issued on your ID; any extra SIMs beyond what you actually use are unauthorized.

Q2. Can I block extra SIMs online without going to the franchise?

For permanent disowning, PTA insists on biometric verification at operators' customer service centers; there is no fully online way to delete all SIMs from your CNIC, except a special overseas flow for people outside Pakistan.

Q3. What's the PTA code to check SIMs on CNIC?

Send your 13‑digit CNIC (without dashes) to 668; PTA's SIM Information System 668 replies with the count of SIMs at each operator.

Q4. How much time does it take to remove a disowned SIM from my CNIC?

After you disown a SIM at the operator's franchise, the operator notifies the user and blocks the SIM if it's not regularized, generally within about 15 days; PTA's SIM database then updates to show reduced counts.

Q5. Is there any fee to disown a SIM?

Operators can apply a disowning charge for SIMs with less than a defined retention period, but PTA has directed a one‑time waiver in cases of illegal issuance without user consent.

Q6. What if the operator refuses to remove extra SIMs from my CNIC?

You can file a complaint with PTA (online complaint portal), referencing the SIM Information System 668 result and your franchise visit; PTA has explicitly told operators to ensure SIM data correction when users raise mismatches.
