SIM Owner Details Online Check 2026: Official PTA Methods (667 & 668)

Want to check the SIM owner details of a mobile number in Pakistan? There are two official PTA-approved ways: check the details of the SIM in your own phone through 667, and check how many SIMs are registered on your CNIC through 668 or the PTA SIM Information System. This guide explains both methods for Jazz, Zong, Ufone and Telenor in 2026.

Important: PTA and mobile companies do not allow anyone to see another person’s SIM owner details by entering their number. Websites that claim to show the “owner name and CNIC” of any number are not official, and many of them use leaked or fake data. Use only the official methods below.

SIM Owner Details Check: Official Methods at a Glance

Method 1: Check SIM Owner Details of Your Own SIM (667)

This method shows the registration details of the SIM that is inserted in your phone. It works the same way on all networks.

1. Open the Messages app on your phone.
2. Type MNP.
3. Send it to 667 from the SIM you want to check.
4. You will receive an SMS with the details linked to that SIM.

It is a useful way to confirm that a SIM you are using, for example one given by a family member, is registered on the right CNIC.

Method 2: Check How Many SIMs Are Registered on Your CNIC (668)

1. Open Messages.
2. Type your 13-digit CNIC number without dashes.
3. Send it to 668.
4. You will receive an SMS showing the number of active SIMs on your CNIC for each operator.

The SMS is charged at about Rs 2 plus tax. Read more: PTA SIM information system 668.

Method 3: PTA SIM Information System Website

1. Open cnic.sims.pk in your browser.
2. Enter your CNIC number.
3. Complete the verification and click Submit.
4. You will see the number of SIMs registered on your CNIC for Jazz, Zong, Ufone and Telenor.

How Many SIMs Can Be Registered on One CNIC?

Under the limit set in 2015, one CNIC can have up to 5 voice SIMs and 3 data SIMs at one time. If you have reached the limit, you must block a SIM you no longer use before getting a new one.

Found a SIM You Do Not Use? Block It

1. Visit the nearest franchise or customer service centre of that operator.
2. Take your original CNIC.
3. Complete biometric verification and ask them to block the SIM.

Do this quickly, because a SIM on your CNIC can be misused for fraud. Read: how to block your SIM card.

How to Find Which Network a Number Belongs To

You cannot see the owner of another person’s number, but you can see which company issued it from the first four digits, for example 0300 is Jazz, 0312 is Zong, 0333 is Ufone and 0345 is Telenor. See the full list: which network code in Pakistan.

Beware of Fake SIM Owner Lookup Websites

• No public website is approved by PTA to show another person’s SIM owner name or CNIC.
• These sites often use leaked data, which is illegal to share and often wrong.
• Some of them collect your own number and CNIC for scams.
• If someone is harassing you from a number, report it to the operator helpline, PTA or the NCCIA (National Cyber Crime Investigation Agency) instead.

668 Shows More SIMs Than You Use? Do This

1. Note the operator name and the number of SIMs shown in the 668 SMS or on cnic.sims.pk.
2. Collect all the SIMs you and your family actually use on your CNIC and count them.
3. If the count does not match, call the helpline of that operator from any number and say a SIM is registered on your CNIC without your permission.
4. Visit the operator’s customer service centre with your original CNIC. After biometric verification they can show you the numbers on your CNIC and block the ones you do not recognise.
5. Check again on 668 after a few days to make sure the extra SIM is removed.

Tips to Protect Your CNIC From SIM Misuse

• Never give a photocopy of your CNIC without writing the purpose and date on it.
• Do not put your thumb on a biometric device at an unknown shop or stall for “free gifts” or prizes.
• Never share OTP codes or your CNIC number with people who call you claiming to be from a bank, PTA or a mobile company.
• Check your SIM count on 668 every few months.
• When you stop using a SIM, get it blocked instead of throwing it away.
