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.
PTA’s SIM Information System is a free website at cnic.sims.pk. You type a 13-digit CNIC, click Submit, and it shows the total number of SIMs registered on that CNIC. It does not show the phone numbers, the owner’s details or any other person’s information.

This page explains what the portal is, how to use it step by step, what it can and cannot tell you, and how to avoid fake look-alike sites. If you want to know whose name a particular SIM is in, that is a different check (667), covered on our SIM owner details hub.
What the SIM Information System is
The SIM Information System is PTA’s public web page for checking SIM registrations against an identity number. It exists so that citizens can see how many SIMs are registered on their CNIC and spot any they did not get themselves. It is run by the Pakistan Telecommunication Authority, the telecom regulator, at the address cnic.sims.pk. The main PTA website is pta.gov.pk.
The data behind it comes from SIM registrations. Every SIM in Pakistan is issued only after fingerprint verification against NADRA records at a franchise or retailer, and the operator records which CNIC each SIM belongs to. The portal tells you the total for the CNIC you enter.
How to use cnic.sims.pk: step by step
- Open a browser and type cnic.sims.pk directly into the address bar. Do not follow links from ads, WhatsApp forwards or unknown sites.
- Check the address bar again. It should read exactly cnic.sims.pk.
- Enter your 13-digit CNIC with no dashes or spaces. The format looks like 6110123456789.
- Click Submit.
- Read the result: the total number of SIMs registered on that CNIC.
The check is free. You do not need a Pakistani SIM or balance, so it works for people living abroad too.
Foreign ID option
Foreign nationals who got SIMs using a passport-style identity number can use the Foreign ID option on the same page. Select it and enter the ID as it was used for registration (an example format is BD989816346), then submit.
NICOP holders
A NICOP, the card for overseas Pakistanis, also has a 13-digit number. Enter it the same way as a CNIC.
What the portal shows, and what it does not
It shows
- The total number of SIMs registered on the CNIC you enter
- The same total for a Foreign ID, if you use that option
It does not show
- The actual mobile numbers
- The owner’s name, address or photo
- Call history, messages or location
- The owner of a number (it does not accept phone numbers)
Why it does not list your numbers
The portal only takes a CNIC, and anyone can type any CNIC. If it listed numbers, anyone who knew your CNIC could collect your phone numbers. Showing only a total lets you spot a problem without exposing your numbers to others.
To find out which SIMs are yours when the total looks high, use these together:
- 668: send your 13-digit CNIC to 668 for a count of active SIMs broken down by operator (about Rs 2 plus tax). This tells you which operator has the extra SIM.
- 667: send MNP to 667 from each SIM you hold to confirm it is in your name.
- The operator: visit the franchise or customer service centre of the operator with the extra SIM, with your original CNIC. They can identify and remove SIMs on your CNIC after fingerprint verification.
Our step-by-step guide on checking every SIM registered on your CNIC covers this in full, and 667 vs 668 explains the two SMS codes.
The network check listed on the portal (76367)
PTA also lists a network check: send N, a space, then the full number (for example N 03001234567) to 76367. The reply names the network the number is on now. PTA lists the charge as Rs 2 plus tax.
This exists because of Mobile Number Portability. People can move their number to another network and keep it, so prefixes such as 0300, 0311, 0333 or 0345 no longer prove the current network. 76367 shows the network only. It never shows who owns the number.
What to do with your result
- The total matches the SIMs you use: nothing more to do. Check again every few months.
- The total is higher: find and remove the extra SIMs as described above. Remember old SIMs, data SIMs in devices, and SIMs you bought for family or staff.
- The total is near or over the limit: the legal limit is 5 voice SIMs and 3 data-only SIMs per CNIC across all networks. See PTA SIM limit per CNIC.
- Your CNIC has expired: renew it with NADRA. PTA reported 244,357 SIMs on cancelled or expired CNICs blocked from January to July 2026.
- You think your CNIC was misused: complain to the operator first and get a complaint number. If unresolved, complain to PTA online or call 0800-55055. For fraud, contact the NCCIA cyber crime helpline 1799 and keep a screenshot of the result.
Staying safe: fake look-alike sites
Because “SIM information” is searched so often, many websites and apps copy the name or look of the PTA portal. Some promise to show the owner name, CNIC or address for any number. These are not official. They typically show leaked or outdated data, or invented results, and some collect the numbers and CNICs people type in.
- The official address is cnic.sims.pk. Look-alike spellings, extra words or different endings are not PTA.
- The official portal only asks for a CNIC or Foreign ID. It does not ask for your phone number, OTP codes, payment or app downloads.
- No official page will show another person’s name from their number.
This website, checksimownerdetails.pk, is an independent information site. It is not PTA, holds no subscriber data and offers no lookup tool. To check your SIMs, use cnic.sims.pk or the SMS codes directly.

Frequently asked questions
Is cnic.sims.pk the same as 668?
Both count SIMs on a CNIC. The portal is free and shows a total. 668 is an SMS that costs about Rs 2 plus tax and breaks the count down by operator.
Can I enter a mobile number on cnic.sims.pk?
No. It takes a CNIC or Foreign ID only. To see whose name a SIM is in, send MNP to 667 from that SIM. See our step-by-step tutorial.
Can I check a family member’s CNIC?
The portal accepts any CNIC, but check other people’s only with their knowledge. The result is a count, not their numbers.
