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 tells you who owns the SIM in your phone: send MNP to 667 from that SIM. 668 tells you how many SIMs are registered on a CNIC: send the 13-digit CNIC to 668. One checks a single SIM’s owner, the other checks a CNIC’s SIM count, and neither can identify a stranger’s number.
Last checked: October 2026
The two codes differ by one digit, so people mix them up. This page puts them side by side, shows which one to use in common situations, and explains where the PTA portal cnic.sims.pk and the 76367 network check fit. For the full picture of SIM checks in Pakistan, see the SIM owner details hub.
667 vs 668: side-by-side comparison
| 667 | 668 | |
|---|---|---|
| Purpose | Find the registered owner of one SIM | Count the active SIMs on one CNIC |
| What you send | MNP | 13-digit CNIC, no dashes |
| Send from which SIM | The SIM you want to check | Any working SIM |
| Result | Owner’s name, partly hidden CNIC, activation date | Number of active SIMs, broken down by operator |
| Shows phone numbers? | No (only describes the sending SIM) | No |
| Cost | Small SMS charge may apply | About Rs 2 plus tax |
| Answers for | The SIM in your hand | The CNIC you type |
Put simply: 667 starts from a SIM and finds the person. 668 starts from a person’s CNIC and counts the SIMs.
How to use each one
667
- Insert the SIM you want to check.
- Open your SMS app and type MNP.
- Send to 667 from that SIM (choose the right slot on a dual-SIM phone).
More detail, including errors and why the keyword is MNP, is in our 667 SIM owner details guide.
668
- Open your SMS app on any SIM.
- Type your CNIC as 13 digits, for example 3520212345679, with no dashes.
- Send to 668.
Our CNIC SIM check guide covers what to do with the count.
Which one do I need? Real situations
I bought a used SIM, or a relative gave me one
Use 667. Send MNP from that SIM. If the reply shows the seller’s or relative’s name, the SIM is still theirs, and they are responsible for what happens on it. PTA requires every SIM to be in its actual user’s name, so arrange an ownership transfer at a franchise with both of you present and giving fingerprints. See SIM ownership and transfer.
I am worried someone has registered SIMs on my CNIC
Use 668, or the free portal cnic.sims.pk. Compare the count with the SIMs you actually use. If it is higher, use 667 on each SIM you hold to find yours, then visit the operator showing the extra SIM with your original CNIC and ask for it to be removed. 667 alone cannot help here, because it only knows about the SIM in your phone.
I got a call or SMS from an unknown number
Neither. 667 cannot check a number you do not hold, and 668 needs a CNIC. What you can do:
- Send N 03XXXXXXXXX to 76367 to see which network the number is on (Rs 2 plus tax). It shows the network only, never the owner.
- Report spam SMS by forwarding it to 9000.
- For fraud, threats or harassment, keep screenshots and the number, and contact the NCCIA cyber crime helpline 1799.
- If your operator is involved (for example, repeated spam), complain to them first and get a complaint number. If unresolved, complain to PTA online or call 0800-55055.
I just finished an ownership transfer
Use 667 from the transferred SIM. The reply should show the new owner’s name.
I want to know if I am over the SIM limit
Use 668 or cnic.sims.pk. The legal limit is 5 voice SIMs and 3 data-only SIMs per CNIC across all networks. See PTA SIM limit per CNIC.
My parent passed away and we still use their SIM
Use 667 to confirm whose name it is in. If it is the deceased person’s, an heir should transfer it. PTA reported 903,230 SIMs on deceased persons’ CNICs disconnected from January to July 2026.
Where cnic.sims.pk and 76367 fit
| Check | What it does | Cost | Overlaps with |
|---|---|---|---|
| 667 | Owner name of the sending SIM | Small SMS charge may apply | Nothing else does this |
| 668 | Active SIMs on a CNIC, by operator | About Rs 2 plus tax | cnic.sims.pk |
| cnic.sims.pk | Total SIMs on a CNIC, in a browser | Free | 668 |
| 76367 | Current network of any number | Rs 2 plus tax | Nothing else does this |
cnic.sims.pk is PTA’s SIM Information System. Type your 13-digit CNIC, click Submit, and it shows the total SIMs registered. It is free, works from abroad without a Pakistani SIM, and has a Foreign ID option for foreign nationals. The 668 reply adds an operator-by-operator breakdown, which helps you know which franchise to visit. Neither shows numbers. Our SIM Information System guide explains the portal.
76367 exists because of Mobile Number Portability. A 0300 or 0345 prefix no longer proves which network a number is on, so this check tells you the current one.
Common mix-ups
- Sending a CNIC to 667. 667 only accepts MNP. Your CNIC goes to 668.
- Sending MNP to 668. 668 expects a 13-digit CNIC, so it will not give an owner name.
- Expecting 668 to list numbers. It only gives counts. To find which SIMs are yours, use 667 on each SIM you hold.
- Using 667 from the wrong slot. On dual-SIM phones, check which SIM sends the SMS.
- Trusting “667/668 online” websites. Both are SMS services. Websites claiming to run them for any number are not official. See SIM database websites.
Frequently asked questions
Which is free, 667 or 668?
Neither is fully free by SMS: 668 costs about Rs 2 plus tax and 667 may cost a small SMS charge. If you want a free SIM count, use cnic.sims.pk.
Can I check someone else’s CNIC on 668?
The service takes the CNIC you type, but use it for your own CNIC, or a family member’s with their knowledge. The result is a count, not their numbers.
