How to Check SIM Owner Details by CNIC Number Free Pakistan 2026

Your CNIC number is the master key to your entire telecom identity in Pakistan. Every single SIM card registered in your name — across Jazz, Zong, Telenor, Ufone, and SCO — is permanently linked to your 13-digit CNIC in PTA’s national database. Knowing how to check all SIM owner details by CNIC number is one of the most important digital safety actions every Pakistani must perform regularly.

This is Pakistan’s most complete guide to checking SIM owner details by CNIC number using the three official PTA methods — all permanently free.

Why Checking SIM Details by CNIC Is Critical in 2026

FIA cybercrime statistics confirm that SIM-based fraud is Pakistan’s fastest-growing digital crime. The majority of cases involve criminals who register SIMs using someone else’s CNIC — either through stolen documents, photocopies left at shops, or corrupt franchise employees.

Once a criminal has a SIM registered on your CNIC, they can:

Conduct financial transactions through JazzCash and Easypaisa in your name
Receive one-time passwords (OTPs) for banking fraud
Commit other criminal acts — all traceable back to your CNIC

PTA’s legal framework holds the CNIC holder responsible for all activity on SIMs registered in their name. This is why checking SIM owner details by CNIC number is not just useful — it is a legal necessity.

Method 1 — Send CNIC to 668 (Official PTA SIM Information System)

This is the most comprehensive and fastest method to check all SIM owner details linked to your CNIC number.

Exact procedure:

Open SMS application on any mobile phone
Type your 13-digit CNIC number — no dashes, no spaces, no gaps
- Your CNIC on card: 35201-1234567-1
- Type it as: 3520112345671
Send this SMS to 668
Receive reply within 5 to 30 seconds

Sample reply:

CNIC Verification Result
Total SIMs registered: 4
Jazz: 2 SIMs (0300-XXXXXXX, 0321-XXXXXXX)
Zong: 1 SIM (0311-XXXXXXX)
Telenor: 0 SIMs
Ufone: 1 SIM (0333-XXXXXXX)
SCO: 0 SIMs
PTA SIM Information System

What to do with this information:

Count the total. Is it what you expected?
Check each operator. Do you recognize all the numbers?
Any unknown number = potential unauthorized SIM. Act immediately.

PTA limits reminder: Maximum 5 SIMs per operator, 25 total. If you are approaching the limit, deactivate unused SIMs before registering new ones. Full details at the SIM information guide.

Method 2 — cnic.sims.pk Web Portal

PTA’s official web portal provides the same CNIC-based SIM check through any browser.

Procedure:

Visit cnic.sims.pk on any browser
Enter 13-digit CNIC without dashes
Complete CAPTCHA
View all registered SIMs

Best for: overseas Pakistanis, those who want a visual record, or when 668 SMS is unavailable.

Method 3 — Check Individual SIM Ownership with 667

While 668 checks all SIMs on your CNIC, the 667 method checks ownership of one specific SIM at a time.

For each SIM you own:

Insert the SIM into your phone
Send MNP to 667
Confirm YOUR name and CNIC appear in the reply

This cross-verification is essential after buying a new SIM — always verify within 24 hours that the franchise correctly registered it to your identity and not someone else’s.

Step-by-Step: What to Do After Getting Your 668 Results

Scenario A — Count Matches What You Registered ✅

No action needed. Screenshot and save results. Recheck in 3 months.

Scenario B — Count Is Higher Than Expected 🚨

Unauthorized SIM registered on your CNIC. Act immediately:

Immediate actions:

Note which operator has the extra SIM
Visit that operator’s franchise with original CNIC
Request SIM disowning (free, biometric-confirmed)
File PTA complaint: 0800-55055
Verify removal after 48 hours

Scenario C — Count Is Lower Than Expected ⚠️

One of your SIMs may have been blocked or deactivated. Contact that operator’s helpline to investigate.

Scenario D — 668 Reply Shows Error ⚠️

Try cnic.sims.pk as alternative. If both fail, your CNIC may have an issue with NADRA records — visit NADRA with original documents.

CNIC Number Format — Common Mistakes That Cause Errors

The single most common reason 668 fails is incorrect CNIC format. Here is every correct and incorrect format:

Format	Example	Works?
13 digits no separators	3520112345671	✅ Correct
With dashes	35201-1234567-1	❌ Will fail
With spaces	35201 1234567 1	❌ Will fail
With dots	35201.1234567.1	❌ Will fail
Fewer than 13 digits	352011234567	❌ Will fail
More than 13 digits	35201123456711	❌ Will fail

Always count your digits before sending. A Pakistani CNIC is always exactly 13 digits.

How Many SIMs Can One CNIC Have in Pakistan?

Operator	Maximum SIMs
Jazz	5
Zong	5
Telenor	5
Ufone	5
SCO	5
Total across all operators	25

If unauthorized SIMs have consumed part of your quota, you must block them before registering new SIMs. Use the 668 check regularly to monitor your remaining quota.

Frequently Asked Questions

Q: Can I check SIM details of another person’s CNIC number? A: No. PTA’s 668 system and cnic.sims.pk only work for the CNIC of the person operating the service. Checking another person’s CNIC SIM details without authorization violates PECA 2016.

Q: Is the 668 service available 24/7? A: Yes. PTA’s 668 SMS service operates 24 hours, 7 days a week.

Q: My CNIC starts with 0 — should I include the leading zero? A: No Pakistani CNIC starts with 0. All CNICs begin with a non-zero digit. If you are unsure, check your physical CNIC card — the 13-digit number is printed clearly on the front.

Q: How long does it take for a new SIM to show in 668 results? A: New SIM registrations typically appear in the 668 database within 24–48 hours of biometric activation.
