How to Check If Your SIM Card is Registered in Your Name

In Pakistan, the registration of SIM cards is strictly monitored and regulated by the Pakistan Telecommunication Authority (PTA). With growing concerns about misuse of mobile numbers for illegal activities, it has become essential for every mobile user to ensure that their SIM is correctly registered under their own name and CNIC.

If your SIM card is not registered under your CNIC, you may face legal problems, financial risks, or lose access to services linked to your mobile number. Fortunately, checking your SIM ownership is simple, free, and can be done in just a few minutes using Sim Ownership, Pakistan’s top SIM and CNIC detail checker.

In this detailed guide, you will learn:

• How to check if your SIM is registered in your name

• How to check SIM card owner name online for free

• How to change SIM registration details online

• How to trace and block unknown SIMs registered on your CNIC

• How to secure your digital identity in Pakistan

Let’s get started.

Why SIM Registration Is Important in Pakistan

A SIM card is more than just a way to make calls or use mobile data. In Pakistan, mobile numbers are linked with:

• Bank accounts and financial services

• Government registrations

• Easypaisa and JazzCash wallets

• Social media and WhatsApp accounts

• Online authentication and OTPs
  
  

If someone else is using a SIM registered under your CNIC, they may misuse your identity, receive sensitive information meant for you, or even involve you in unlawful activity. For this reason, the government has made it mandatory to register all SIMs through Biometric Verification System (BVS).

How to Check If Your SIM Card is Registered in Your Name

There are multiple simple methods you can use to verify your SIM ownership in Pakistan.

1. Check Through Your Mobile Phone (No Internet Required)

Every telecom company provides an SMS or USSD code to check the registration status of your SIM card. This is the fastest and most direct method.

For Jazz Users:

• Dial *99#

• Your registered name will be displayed on your screen
  
  

For Zong Users:

• Send a blank SMS to 667

• You’ll get an SMS with the name and CNIC of the SIM owner
  
  

For Telenor Users:

• Send a blank SMS to 667

• You will receive a message showing the registered owner’s details
  
  

For Ufone Users:

• Dial *336# and select option 1 (for verification)

• You can also send a blank SMS to 667


For Warid Users:

• Use the same method as Jazz users (*99#)

Note: Charges may apply for SMS, depending on your network. USSD codes are usually free.
