How to Check SIMs on Your CNIC in Pakistan

Check SIMs registered on your CNIC using the SIM Information System or 668 SMS. Learn what results mean and how to report unfamiliar connections.

You can check SIMs registered against your CNIC through the SIM Information System, or by sending your CNIC number to 668 by SMS. The online form asks for your identity number and a verification check. Use these services for your own CNIC, and keep the result private.

The important distinction is that checking the number of registered connections is different from getting a list of every phone number. Treat the result as a starting point for reviewing your registrations, not as a public SIM-owner lookup tool.

What you need before checking

Keep your CNIC available so you can enter all 13 digits accurately. For the online method, you also need an internet connection and a browser. For SMS, you need a working mobile connection that can send a message to a short code.

Do the check on a device you trust. Avoid asking a stranger to type your CNIC into their phone, and do not leave a screenshot of the result in a public chat. Your identity number is not something to post when requesting troubleshooting help.

Method 1: Check SIMs on CNIC online

  1. Open cnic.sims.pk directly in your browser.
  2. Select the CNIC option if another identity type is selected.
  3. Enter your 13-digit CNIC number without spaces or hyphens.
  4. Complete the verification shown on the page yourself.
  5. Submit the form and review the registered SIM totals it returns.

Check the spelling of the domain before entering anything. A search result or advertisement using words such as “official SIM data” is not enough to establish that a website is the right service.

The form also provides a Foreign ID option. Use the identity type that actually applies to you rather than trying to fit a passport or other document number into the CNIC field.

Method 2: Send your CNIC number to 668

Open your messaging app, start a new SMS addressed to 668 and enter your CNIC digits in the message. Review the number carefully before sending, then read the reply. SMS charges may apply; check your operator’s current tariff rather than assuming the message is free.

Sending a CNIC number to 668 is described in cybercrime-prevention guidance hosted by PTA’s National Telecom CERT. You do not need to send a photograph of the identity card as part of this text-message check.

If your phone has two SIMs, note which connection is selected for sending. A disabled SIM, weak signal or short-code messaging restriction can prevent a response even when the CNIC digits are correct.

How to understand the result

Compare the reported connections with the SIMs you know you have registered. Think beyond the phone in your hand: you may have an older line, a second handset or a data connection that you no longer use regularly.

For example, if you remember one connection with an operator but the result shows two, do not immediately assume the second one belongs to a criminal. Write down the discrepancy and ask that operator to check its registration record through an authenticated support process.

Equally, do not ignore an unexplained connection simply because you cannot see its full number. The next useful action is verification with the operator, rather than searching unofficial databases for more personal information.

What to do if you find an unfamiliar SIM

Contact the relevant mobile operator through its official support channel or an authorized service center. Explain that the registered count does not match the connections you recognize. Ask what identity verification is needed to investigate and, where appropriate, block an unauthorized connection.

Bring your original identification if the operator asks you to attend in person. Keep the complaint reference and the date of your visit. Before leaving, ask what has actually been changed and when you should check the registration result again.

If the issue remains unresolved, use the complaints route linked from PTA’s official website. Describe the facts and include the operator’s reference through the official complaint process. Never put your complete CNIC in a public comment to attract attention.

Common problems and sensible fixes

The CNIC is rejected

Count the digits and remove spaces or hyphens. Compare your entry with the card itself instead of retyping from memory. If it still fails, record the error wording without exposing the identity number and contact official support.

The verification code does not work

Refresh the verification image if the page offers that option, then enter the newly displayed characters. Use the current image; an older code may no longer apply after refreshing the page.

No SMS reply arrives

Confirm that the message was sent to 668, check signal and messaging availability, and allow time for a reply. The online method is an alternative if SMS is unavailable. Repeated messages can create unnecessary charges.

The result has not changed after a complaint

Follow up with your complaint reference. Ask the operator about processing and record-update timing. Do not assume that one service’s display refreshes immediately after another system is changed.

Keep a small, private record

Record the date of the check, the operator involved and any complaint reference in a private note. You usually do not need multiple unprotected copies of your CNIC photo to track a support issue.

If your immediate problem is simply identifying a Zong SIM already in your phone, see how to check your Zong number. That solves a different question from checking all connections registered against an identity document.

Frequently asked questions

Will this show someone’s location or call history?

No. This guide covers checking your registered SIM count. It does not provide access to private communications, live location or someone else’s account.

Should I upload my CNIC to a SIM-checking app?

Use the established web or SMS route above. An unfamiliar app asking for your identity-card image, contacts and messages is not necessary for this check.

Does checking automatically block an unknown SIM?

No. Reviewing the result and requesting action from the operator are separate steps. Keep following the complaint until you receive a clear resolution.
