How to Send SMS to 668 to Check SIMs

This is the core process, and it only takes a minute from start to finish.

Step 1: Open Your SMS App

To use the service, have a mobile phone with a Pakistani SIM and your CNIC number ready; no internet is needed for SMS.

Step 2: Enter Your CNIC Number

• Enter your 13-digit CNIC number as a single string without any dashes or spaces.
• Use only your own CNIC for checking your SIM records.
• Avoid posting your CNIC publicly to protect your sensitive personal information.

Step 3: Send the CNIC to 668

To send a text message, type your 13-digit CNIC number (without dashes) and send it to the shortcode 668. Example format only; do not use a real CNIC in examples or screenshots.

Step 4: Wait for the Response

The system checks your CNIC in the PTA’s SIM database after you send a message, providing a list of SIMs registered under your name, sorted by mobile operator.

How Long Does the SMS Response Take?

Most users receive responses within seconds to a couple of minutes. Response times may vary due to network traffic and system activity, so if it takes longer than usual, it’s normal to wait before assuming there’s a problem.

What Information Does 668 Provide?

The 668 service is intended to inform users about the number of SIMs registered against their CNIC and the associated operators. It functions as a count-and-verify tool rather than a complete data lookup service.

The key distinction is between the number of SIM cards linked to your account and actual phone numbers. The service helps you track connections under your name to identify if the count is unusually high, rather than listing all phone numbers.

Example of an SMS 668 SIM Check Result

Example only: this is an illustrative format and not an actual PTA response.

Check your SIM results by comparing the total number listed with the SIMs you own. If there’s an unknown SIM, investigate it, as it may be old or registered without your knowledge.

How to Check SIMs Registered on Your CNIC Online

To check your SIM registration information without a Pakistani SIM, you can use the PTA’s Official SIM Information System online. Follow these steps:

• Visit the official tool to get complete Detail
• Visit the official PTA web portal and verify the domain for authenticity.
• Enter your 13-digit CNIC number.
• Complete the required security verification, such as a CAPTCHA.
• View your SIM registration details, which will show your SIM count by operator.

This online method is especially beneficial for overseas Pakistanis or anyone without local SIM access, as it only requires an internet connection.

SMS 668 vs Online SIM Check

If you need a quick answer while on your phone, SMS to 668 is the fastest option. If you’re using a laptop, don’t have a Pakistani SIM, or are outside Pakistan, the online portal is more practical. Both methods provide the same results.

Does 668 Show the Actual SIM Numbers?

The 668 system provides a count of SIMs registered under your CNIC, categorized by operator, but does not list individual mobile numbers associated with that CNIC. A count indicates how many SIMs exist, but it doesn’t provide a complete directory of numbers. It’s important to understand that full number details are available only to the CNIC holder for their own account, not for looking up others’ SIMs. If your count does not match the SIMs you use, contact your mobile operator or check the online portal for more information.

What If You Find an Unknown SIM on Your CNIC?

This is where a routine check can actually save you from a real problem: an unrecognized SIM under your name is a legitimate security concern.

Compare the Result With Your Current SIMs

• List all SIM cards you own and actively use.
• Compare each SIM against the provided count and operator breakdown.
• Identify any remaining SIMs as “unknown” that need further investigation.

Contact the Relevant Mobile Operator

To verify an extra SIM, contact the respective operator directly via their helpline or service center, as they have the specific details for that connection.

Ask About Blocking or Disowning the SIM

If you confirm a SIM isn’t yours, inquire with the operator about the process to disown or block it, as procedures and requirements can vary and change over time.

Escalate an Unresolved Complaint

If the operator fails to resolve the issue, PTA offers its own complaint channels, including an online portal and a dedicated helpline, allowing consumers to escalate unauthorized SIM issues beyond the operator.

Protect Your CNIC

To prevent unauthorized registrations, keep these key habits in mind:

• Avoid sharing photographs of your CNIC unless necessary.
• Do not give your OTP to anyone, even if they claim to be from your operator or PTA.
• Refrain from providing your fingerprint or biometric data to unofficial agents or shops.
• Be cautious of SIM-registration scams that require your CNIC copy without proper biometric verification.

What to Do If SMS to 668 Is Not Working

• Check CNIC Number: Ensure it’s exactly 13 digits with no dashes or spaces.
• Check SMS Format: Send only the CNIC number without extra text or symbols.
• Check Mobile Service: Verify that your SIM has active service and can send SMS.
• Try Again Later: If issues persist, wait a while and try sending again due to potential service slowdowns.
• Use Online Alternative: If SMS fails, use PTA’s official web-based SIM Information System.
• Contact Support: If all else fails, reach out to your mobile operator or PTA for assistance.
