Check the SIMs on Your Own CNIC or Number
Pick a tab and press the button to see the official PTA check for your own CNIC, or for the SIM in your phone. Nothing you type leaves this page, and this site does not look up other people's numbers.
667 is the short code you use to see whose name a SIM is registered in. From the SIM you want to check, type MNP and send it to 667. The reply shows the registered owner’s name, a partly hidden CNIC and the activation date, for that sending SIM only.

This page covers the 667 service in depth: how to send it, how to read the reply, what it cannot do, and what to do when it fails. For all the official checks side by side, see the SIM owner details hub.
What the 667 service is
667 is an SMS short code that works on Pakistani mobile networks. You send one keyword, MNP, and receive the registration details held for the SIM that sent it. Every SIM in Pakistan is issued only after fingerprint verification against NADRA records, so the name in the reply is the person whose CNIC and fingerprints were used when the SIM was issued, or the person it was later transferred to.
It is a self-check. It answers one question: “Who is this SIM, the one in my phone right now, registered to?”
How to send MNP to 667: exact steps
- Insert the SIM you want to check into your phone.
- Open the built-in Messages (SMS) app. Chat apps such as WhatsApp will not work.
- Start a new message and enter 667 as the recipient.
- Type MNP as the message. No CNIC, no number, no extra words.
- On a dual-SIM phone, choose the SIM you are checking as the sending SIM.
- Press send and wait for the reply SMS.
Roman Urdu: jis SIM ka malik maloom karna hai, usi SIM se “MNP” likh kar 667 par bhejein.
What the reply contains
| Item in the reply | What it tells you |
|---|---|
| Registered owner’s name | The person the SIM is legally registered to, and who PTA holds responsible for its use |
| Partly hidden CNIC | Some digits of the owner’s CNIC, with the rest masked. Enough to match against your own card, not enough to reveal someone’s full identity |
| Activation date | When the SIM was activated. Useful to spot a SIM that was re-registered or is older than you thought |
Compare the name and visible CNIC digits with your own CNIC. If they match, the SIM is yours. If they do not, the SIM belongs to someone else in the eyes of the operator and PTA.
Cost
A small SMS charge may apply, at your network’s standard rate. Keep some balance on the SIM before sending. This site cannot confirm an exact amount for every package, so check with your operator if the charge matters to you.
Why the keyword is “MNP”
MNP stands for Mobile Number Portability, the system that lets you move your number to another network while keeping it. Sending MNP to 667 does not start a network change. It only returns the SIM’s registration details. Porting a number is a separate request done at a franchise with biometric verification.
Portability is also why prefixes no longer prove a network. A number starting 0300 or 0333 may now be on a different operator. If you need a number’s current network, send N, a space and the full number to 76367 (Rs 2 plus tax). That shows the network only, never the owner.
Limits: what 667 cannot do
- It only checks the sending SIM. You cannot type another number into 667 and get that person’s name. There is no official service in Pakistan that does this for the public.
- It does not count your SIMs. It knows nothing about other SIMs on the same CNIC. For that, use 668 or cnic.sims.pk.
- It does not show phone numbers on a CNIC, call history, address or location.
- It may not work from data-only SIMs that cannot send SMS.
Websites and apps that claim to show “SIM owner details” for any number you type are not using 667. They typically show leaked, outdated or made-up data, and may collect the numbers and CNICs you enter. See our warning on SIM database websites.
Common errors and fixes
No reply
Check signal, balance and that you typed 667 correctly. Make sure a normal SMS goes through. Wait a few minutes and try once more instead of sending repeatedly.
Error or “invalid” message
Send only MNP. Remove spaces, punctuation and anything else in the message box. Some phones add a signature to every SMS: turn it off in message settings.
The reply shows the name of my other SIM’s owner
Your dual-SIM phone sent the message from the other slot. Set the correct SIM for SMS in your phone’s SIM settings, or remove the other SIM, then send again.
The name is not mine
If you bought or received the SIM from someone, it is still registered to them. PTA requires every SIM to be registered in the name of its actual user, so arrange a transfer at a franchise with both people present. Our guide on checking SIM ownership and transferring a SIM explains the process. If the SIM was bought new by you and shows another name, visit the operator with your original CNIC and get a complaint number.
When to use 667, and when to use 668 instead
| Situation | Use |
|---|---|
| You have a used or family SIM and want to know whose name it is in | 667 |
| You finished an ownership transfer and want to confirm it | 667 |
| You want to know how many SIMs are on your CNIC | 668 or cnic.sims.pk |
| You fear someone registered SIMs on your CNIC | 668 or cnic.sims.pk |
| You want to know which network a number is on | 76367 |
The two codes are often confused because they differ by one digit. Our 667 vs 668 comparison goes through more cases. For step-by-step instructions on all four checks with troubleshooting, see how to check SIM owner details.
Does 667 work on every network?
The MNP to 667 check is used across Pakistani networks, including Jazz, Zong, Ufone, Telenor and SCOM. Telenor Pakistan merged into PTML (which runs Ufone) in July 2026, with service continuity promised for customers of both brands. If 667 does not respond on your SIM, call your operator’s customer care from that SIM (Jazz 111, Zong 310, Ufone 333, Telenor 345).
Frequently asked questions
Is 667 an official service?
It is a short code on Pakistani networks that returns the SIM’s own registration record. It is not a lookup for other people, and this website has no connection to it.
Can I use 667 to identify a caller?
No. If a call or SMS is fraud or harassment, keep evidence, report spam SMS to 9000, and contact the NCCIA cyber crime helpline 1799.
