How to Check SIM Registration and Owner Name in Pakistan
If you are wondering how to check SIM registration in Pakistan, you have several official options. Every SIM sold here must be biometrically registered on the real owner’s CNIC under Pakistan Telecommunication Authority (PTA) rules, which limit each CNIC to five voice SIMs and three data SIMs across all networks. This guide, updated 15 October 2026, explains how to check SIM ownership details using simple SMS codes, PTA’s free online portal, and network apps — so you can confirm a number is yours and catch any fraudulent registration on your CNIC.
Checking matters because SIMs registered on your CNIC without your knowledge can be misused for fraud, spam, or even criminal activity, leaving you exposed to legal trouble. A quick audit takes less than a minute and gives you complete peace of mind, which is why security experts recommend running one regularly.
How to Check SIM Registration by SMS: The 667 and 668 Codes
Method 1 — SMS “MNP” to 667. From any SIM — Jazz, Zong, Telenor, Ufone, ONIC or SCOM — send the text MNP to 667. Within seconds you receive a reply showing the registered owner’s name, a partially masked CNIC number, and the SIM’s activation date. This is the quickest official way to verify who owns the SIM you are holding, and it works identically on every major network in Pakistan. Keep a little balance on the SIM, since the SMS itself may carry a small operator charge.
Method 2 — SMS your CNIC to 668. If you want a full audit, text your 13-digit CNIC number (no dashes) to 668. The reply lists how many SIMs are registered on your CNIC, broken down by operator. A nominal charge of about Rs. 2 plus tax may apply. Anyone who wants to know how to check SIM registration across every network at once should start with this code, since it also catches numbers on networks you do not use yourself.
Using PTA’s Free Online Portal for SIM Information
For a detailed and completely free alternative, visit PTA’s SIM information portal at cnic.sims.pk from any browser. Enter your 13-digit CNIC and the system shows a colour-coded breakdown that separates voice SIMs from data SIMs, including registration dates for each number. For anyone living abroad, knowing how to check SIM registration online is especially useful, because the portal works from outside Pakistan too — ideal for NICOP holders who cannot visit a franchise in person. Unlike the 668 SMS, the portal costs nothing, which makes it the best option for regular monthly checks. In short, a browser-based sim registration check through cnic.sims.pk is the official PTA route for anyone who wants paperwork-free results, while the 667 SMS remains the quickest way to check sim number details on the handset itself.
Network-Specific USSD Codes for SIM Details
Each operator also offers its own self-service codes for SIM information, which is handy if you want details about one network only:
- Jazz: dial *321# to see all Jazz SIMs on your CNIC; call helpline 111 for support. Another code widely cited for ownership checks is *444*6*1#.
- Zong: SMS your CNIC to 310 to list your Zong numbers; helpline 310.
- Telenor: dial *345# for SIM information; helpline 345.
- Ufone: dial *336# for account and SIM details; helpline 333.
You can also manage SIM details through the official apps — Jazz World, My Zong, My Telenor, and My Ufone — which show registered numbers alongside balance and bundle information.
What to Do If You Find a SIM You Never Registered
If your audit turns up a number you did not buy, act fast. Visit the nearest franchise or customer service centre of that network with your original CNIC and ask for the number to be disowned or deactivated — biometric verification confirms you are the CNIC holder, and the franchise must act within 24 hours under PTA rules. You can also file a formal complaint with PTA at complaint.pta.gov.pk or call the free PTA helpline 0800-55055, which operates around the clock. If the unknown SIM was used for fraud, report it to the FIA Cybercrime helpline at 9911 as well, and keep your complaint reference numbers safe for follow-up.

Frequently Asked Questions
What is the fastest way to check SIM ownership?
Send MNP to 667 from the SIM. The reply arrives in seconds with the owner’s name, a masked CNIC, and the activation date.
Can I look up someone else’s SIM details?
No. The 667 reply only covers the SIM the SMS is sent from. PTA offers no public lookup of other people’s numbers, and accessing another person’s data without consent can breach the Prevention of Electronic Crimes Act.
How many SIMs can be registered on one CNIC?
Five voice SIMs and three data SIMs, combined across all six operators — a cap upheld by the Supreme Court of Pakistan.
Is there any fee for checking SIM registration?
The 667 SMS may carry a small operator charge and 668 costs about Rs. 2 plus tax. If you want to know how to check SIM registration without spending anything at all, use the free cnic.sims.pk portal.
How often should I run a SIM audit?
Once a month is a good habit. A 30-second check catches unauthorised registrations early, before they can cause legal or financial trouble.
How to Check SIM Registration in Pakistan
To check SIM registration details, send your CNIC number (without dashes) via SMS to 668 — the PTA’s official service — and you will receive the count of SIMs registered against your identity.

The standard sim registration check code *668# also works on most networks, and the pta sim verification portal lets you see how many sims on my cnic are active. If you find unknown SIMs, visit the franchise immediately to block them and protect yourself from misuse.
