How to Check How Many SIMs Are Registered on My CNIC in Pakistan

Wondering how many SIMs are registered on my CNIC in Pakistan? You can check the number of SIMs issued against your identity card online through Pakistan's SIM Information System. You can also use the 668 SMS method recommended in PTA cyber-safety guidance.

Checking your SIM count is a good security habit. If an unknown SIM has been issued against your identity, you should take action instead of ignoring it.

This 2026 guide explains how to check SIMs registered on your CNIC, use the online SIM Information System, check through 668, and deal with a SIM you don't recognize.

How Many SIMs Are Registered on My CNIC?

You can find how many SIMs are registered on your CNIC through the SIM Information System.

The online service asks for your 13-digit CNIC number and displays the number of SIMs associated with it.

The results are divided by mobile network and also show the total SIM count.

This means you don't have to guess whether old or forgotten SIMs are still associated with your identity.

How to Check SIMs Registered on CNIC Online

The online method is straightforward.

Follow these steps:

1. Open the SIM Information System. 2. Enter your 13-digit CNIC number. 3. Enter the CNIC without dashes. 4. Complete the verification shown on the page. 5. Click Submit. 6. Review the network-wise SIM count. 7. Check the total number of SIMs registered against the CNIC.

The system currently displays separate network columns or entries along with the total number of SIMs.

Never enter your CNIC into random websites simply because they claim to provide “SIM owner details.” Use the recognized SIM Information System for checking SIMs associated with your own identity.

Check SIMs on CNIC Through 668

You can also check the SIMs issued in your name through SMS.

PTA's published cyber-safety guidance recommends periodically checking the number of SIMs issued in your name by sending your CNIC number to 668.

The process is simple:

1. Open the Messages app on your phone. 2. Type your CNIC number. 3. Enter it without dashes. 4. Send the message to 668. 5. Review the information received in response.

For example, if a CNIC were:

12345-1234567-1

you would enter it as:

1234512345671

and send it to:

668

Use your own CNIC rather than the example above.

Online SIM Check vs 668 SMS

Both methods can help you check the SIMs associated with your identity.

The online SIM Information System is useful when you have internet access. It displays the network-wise number of SIMs and the total count.

The 668 method is useful when you prefer SMS or don't want to use the website.

Whichever method you choose, the important thing is to check your SIM count from time to time.

What Information Does the Online SIM Check Show?

The SIM Information System is designed primarily to tell you how many SIMs are registered against a CNIC.

The current results page shows network information and the number of SIMs associated with each network, followed by the total.

It should not be confused with websites that claim to reveal someone's private phone number, home address, family information or other confidential records.

If your goal is simply to find out whether extra SIMs have been issued against your identity, the official-style SIM count system is what you need.

Does CNIC SIM Check Show Mobile Numbers?

This is an important distinction.

The public SIM Information System is primarily a SIM-count service. Its interface displays the number of SIMs associated with the entered CNIC across the listed networks.

Don't assume that entering a CNIC should reveal every complete mobile number associated with that person.

A person's CNIC and phone information are sensitive personal data.

If you discover an unexpected SIM count, contact the relevant mobile operator rather than using unofficial “SIM database” websites that promise to reveal private subscriber information.

Why Should You Check SIMs Registered Against Your CNIC?

An unauthorized SIM issued against your identity can create serious security problems.

PTA's cybercrime guidance specifically discusses illegal SIM issuance and recommends that people periodically check the number of SIMs issued in their names.

This matters because a SIM associated with your identity could potentially be misused without your knowledge.

A quick CNIC SIM check can help you spot a problem earlier.

It's especially worth checking if:

• You've lost an old SIM.
• You previously used several mobile networks.
• You don't remember closing an old connection.
• Your CNIC information may have been exposed.
• The displayed SIM count is higher than you expected.
• You've previously provided biometric verification for a SIM.

What Should I Do If an Unknown SIM Is Registered on My CNIC?

Suppose you check your CNIC and expect to see two SIMs, but the system shows three.

Don't ignore the extra connection.

PTA's cyber-safety guidance advises users to block illegally issued SIMs discovered in their names.

Your next step should be to identify the relevant mobile network from the SIM-count results and contact that operator through its official support channel or service centre.

Take your original CNIC with you if an in-person verification is required.

Explain that the SIM count against your CNIC includes a connection you don't recognize and ask the operator to verify and resolve the issue.

Avoid paying unofficial agents who claim they can secretly access or delete telecom records.

How to Report an Unauthorized SIM

Start with the mobile operator whose SIM count appears incorrect.

If the issue isn't resolved appropriately, PTA also operates a Complaint Management System for telecom complaints.

The PTA complaint system uses a registered account and CNIC-based sign-in to allow users to submit and manage complaints.

When reporting an issue, provide accurate information and clearly explain that you believe an unauthorized SIM is associated with your CNIC.

Keep any complaint or reference number you receive.

Is It Safe to Enter CNIC Online?

A CNIC is sensitive personal information, so you should be careful about where you enter it.

Use the SIM Information System for this particular check and avoid unknown websites offering services such as:

“Find anyone's SIM owner details”

or

“Get complete personal data from CNIC.”

These aren't the same thing as checking the number of SIMs issued against your own CNIC.

PTA's telecom data regulations treat information such as names, addresses, CNIC/passport numbers and phone numbers as personal data and require protection against unauthorized disclosure.

So, keep your CNIC and telecom information private.

How Often Should You Check Your CNIC SIM Count?

There's no need to obsessively check it every day.

However, PTA's cyber-safety material recommends periodically checking the number of SIMs issued in your name.

A check every now and then takes very little time and can help you notice an unexpected change.

It's also sensible to check after losing a SIM, dealing with suspicious identity activity, or discovering something unusual with one of your mobile accounts.

Can Someone Register a SIM Without Proper Verification?

SIMs are supposed to be issued according to the required subscriber verification procedures.

PTA's cybercrime guidance states that selling or providing a SIM without the required verification or authentication of subscriber credentials is illegal.

The same guidance highlights risks associated with illegal SIM issuance and warns users to be careful when providing biometric information.

That's another reason to use authorized cellular franchises and official operator channels when buying or replacing a SIM.

Be Careful When Providing Fingerprints for a SIM

Biometric verification is sensitive.

PTA's National Telecom CERT publishes security-awareness material specifically warning people to be vigilant when providing fingerprints for a new SIM.

Don't provide biometric verification to random individuals, roadside sellers or someone claiming that your fingerprints are required for an unrelated service.

When purchasing or replacing a SIM, use an authorized operator channel.

Can I Check Which Network a Mobile Number Uses?

The SIM Information System currently also provides information about checking the network of a mobile number.

Its page states that users can send:

N 03xx3456789

to:

76367

to check the network of a number.

The website currently lists the charge as Rs. 2 + tax.

Keep in mind that checking which network a number belongs to is different from checking the number of SIMs registered against your CNIC.
