Learn How to Use 667 MNP Service to Check SIM Registration, understand MNP, required documents, verification benefits, privacy rules, and official PTA resources.
If you want to verify the registration information of a SIM that you currently have, the 667 MNP service is an important telecom facility in Pakistan. Many people confuse 667 with 668, but the two services have different purposes.
The 668 service is generally used to check the number of SIMs registered against your CNIC, while 667 is associated with Mobile Number Portability (MNP) and can be used during MNP-related processes and for checking information associated with the SIM sending the request. PTA has also listed 667 for checking mobile number portability. ARY News
In this guide, we explain How to Use 667 MNP Service to Check SIM Registration in simple language. You will learn what MNP means, how the 667 SMS method works, what information you may need, the difference between 667 and 668, privacy precautions, and what to do if your SIM registration information is incorrect.
What Is MNP?
MNP stands for Mobile Number Portability.
It allows a mobile user to move an existing mobile number from one network to another while keeping the same mobile number. For example, a person can move their number from one mobile operator to another without changing the number itself.
Jazz explains MNP as the process of changing your mobile network while keeping your existing number. Its current instructions also use MNP sent to 667 as part of the port-in process. Jazz
This is why 667 is different from a normal CNIC SIM-count service.
How to Use 667 MNP Service to Check SIM Registration
If you are checking the registration information of the SIM that is currently in your possession, the commonly used process is straightforward.
Step-by-Step Method
- Insert the SIM you want to check into your mobile phone.
- Open your phone’s Messages/SMS application.
- Type MNP in the message.
- Send the SMS to 667.
- Wait for the response.
- Review the information returned for that SIM.
The important point is that the request should be sent from the SIM you are checking.
The 667 service is not a public tool for entering someone else’s mobile number and obtaining that person’s private subscriber information.
Example
Suppose you have an old SIM in your phone and you are unsure about its registration details.
You can use that same SIM to send:
MNP
to:
667
The response is intended to relate to the SIM from which the request was sent.
What Does 667 Have to Do With SIM Registration?
The connection between 667 and SIM registration comes from the relationship between MNP and subscriber information.
Historical government documentation explains that a SIM Identity System using 667 was introduced to allow customers to check information associated with a particular SIM, and that the same system later formed part of the Mobile Number Portability process. Cabinet Division
This is different from checking every SIM registered against your CNIC.
For a complete CNIC-level SIM count, the PTA SIM Information System is the more relevant facility. The official SIM Information System currently asks users to enter their CNIC to find the total number of SIMs registered against it. SIM Information System
667 vs. 668: What Is the Difference?
This is one of the most common questions.
Although both numbers are related to SIM verification, they serve different purposes.
| Service | Main Purpose | What You Check |
|---|---|---|
| 667 | MNP / SIM-related verification | Information associated with the SIM sending the request |
| 668 | CNIC SIM check | Number of SIMs registered against your CNIC |
| PTA SIM Information System | Online CNIC verification | SIM counts by network |
| 76367 | Network checking | Current network of a mobile number |
The official PTA SIM Information System currently provides a CNIC-based online check and displays network-wise SIM counts. SIM Information System
So, if your question is “How many SIMs are registered against my CNIC?”, you should look at the CNIC-based 668/online method.
If your question is “What registration information is associated with the SIM I currently have?”, 667 is the relevant MNP-related service.
Required Information and Documents
For a basic 667 SMS check, the most important requirement is access to the SIM you want to verify.
You should have:
- The physical SIM you want to check
- A mobile phone capable of sending SMS
- Network service on the SIM
- The ability to send the SMS to 667
For more detailed SIM registration issues, you may also need your original CNIC.
If you visit a mobile operator’s service center because of a registration problem, the operator may require identity verification before taking action.
Keep Your Original CNIC Safe
Your CNIC contains sensitive personal information. Do not send a picture of your CNIC to an unknown person who claims they can check SIM ownership for you.
For SIM-related problems, use the relevant mobile operator’s official customer service or service center.

Benefits of Checking Your SIM Registration
Using a legitimate SIM verification method can provide practical information about your own mobile connection.
1. Confirm Your SIM Registration
If you have an older SIM and are unsure about its registration, a SIM-related verification check can help you understand the information associated with the connection.
2. Support MNP Requests
667 is directly connected with the Mobile Number Portability process. Operators use the MNP process when a customer wants to move a number to another network while retaining the number. Jazz
3. Manage Your Mobile Connections
Checking your own SIM information can help you keep better track of the connections you use.
4. Identify Registration Problems
If the information associated with a SIM does not match your records, you can contact the relevant operator and ask for clarification.
5. Improve Personal Security Awareness
Knowing which SIM you are using and how it is registered can help you manage your telecom accounts more carefully.
These benefits should not be exaggerated. 667 does not provide a legal way to search a public database of other people’s private information.
Can 667 Be Used to Check Someone Else’s SIM?
No. You should not use telecom services to obtain another person’s confidential subscriber information without authorization.
If you have a mobile number belonging to another person, that does not give you the right to obtain their private CNIC information, address, or other subscriber records.
The responsible approach is to use 667 for the SIM you possess and use the CNIC-based PTA system for checking registrations associated with your own CNIC.
What If Your SIM Information Is Incorrect?
Sometimes a user may discover that the registration information associated with a SIM does not match what they expected.
If this happens, do not try to resolve the matter through an unofficial SIM database.
Instead:
- Keep the SIM with you.
- Keep your original CNIC available.
- Contact the relevant mobile network operator.
- Explain the registration problem.
- Follow the operator’s identity-verification process.
- If necessary, use the official PTA complaint mechanism.
PTA’s cybersecurity guidance advises consumers to periodically check the number of SIMs issued in their name and take action regarding illegally issued SIMs. NTCERT
667 Is Not the Same as a SIM Database
There are many websites online that use terms such as SIM owner details, SIM database, or SIM information.
You should be careful with such websites.
A third-party website should not be treated as an official PTA database simply because it mentions PTA, MNP, CNIC, or SIM verification.
Do not trust websites that promise unauthorized access to:
- Another person’s CNIC
- Private home address
- Call records
- Private subscriber databases
- Confidential telecom information
- Personal information connected with an unknown mobile number
Use official telecom channels whenever you need to verify or correct your own information.
PTA SIM Information System and 667
It is useful to understand how these services work together.
The PTA SIM Information System is designed for checking the number of SIMs associated with a CNIC. Its current website asks for a CNIC and displays SIM counts by network. SIM Information System
The 667 MNP service, on the other hand, is associated with Mobile Number Portability and SIM-related verification.
Therefore, you should select the method based on what you actually want to check.
If You Want to Check:
SIMs registered on your CNIC:
Use the PTA CNIC SIM Information System / relevant 668 method.
A SIM currently in your possession:
Use the relevant 667 MNP process.
Mobile number portability:
Use the MNP process associated with 667.
This distinction can prevent confusion between the two services.
Privacy and Security Tips
SIM registration is connected to personal identity information, so privacy should always be taken seriously.
Follow these basic precautions:
- Never publish your CNIC publicly.
- Do not share OTPs with anyone.
- Do not give your biometric information to unauthorized people.
- Avoid unknown websites claiming to have private SIM databases.
- Do not ask strangers to check your SIM registration for you.
