The government has made digital Know Your Customer (KYC), or e-KYC, mandatory for getting a new mobile SIM connection. It has also banned the issuance of bulk SIM cards to general consumers as part of measures to prevent telecom-related fraud, Bhaskar English reported.

Under the rules of the Department of Telecommunications (DoT), an individual can have a maximum of nine mobile connections registered in their name using their Aadhaar details. The limit is six connections in Assam, the North-Eastern states and Jammu & Kashmir.

How can you check mobile connections issued in your name?

The government has introduced the Sanchar Saathi portal to help consumers identify and report unauthorised mobile connections.

The portal includes the Telecom Analytics for Fraud Management and Consumer Protection (TAFCOP) facility, which allows users to check all mobile connections issued in their name and report numbers they do not recognise.

To check your mobile connections:

  • Visit the official Sanchar Saathi website and select the option to check mobile connections issued in your name.
  • Enter your active 10-digit mobile number.
  • Enter the captcha code displayed on the screen.
  • Complete the verification using the OTP sent to your mobile number.
  • Once verified, the mobile numbers registered in your name will be displayed.
  • If you find a number that you do not recognise, you can report it through the portal instead of ignoring it.
