To authenticate the user using DSC, a person should first register the DSC in the GST Portal. This can be done from the user login in the GST Portal. You can visit our blog ‘How to register DSC’ for the step by step details to do this.

In the GST portal, using DSC for user authentication is mandatory for companies and Limited Liability Partnerships (LLP).

Electronic Signature (E-Sign)

Electronic Signature (E-Sign) is an electronic signature service in India which facilitates an Aadhar holder to digitally sign a document.

In the GST Portal, a person can digitally sign a document using a One Time Password (OTP) which will be sent to the mobile number registered with Aadhar.

Electronic Verification Code (EVC)

In the GST portal, a person can authenticate the user using an OTP (One Time Password). The OTP will be sent to the registered mobile number of the Authorized Signatory. The OTP is called the Electronic Verification Code (EVC) and a person who wants to do the user authentication using an OTP can select this method.

Hence, all tax payers can now easily perform activities of GST compliance completely online. Companies and LLPs should note that they mandatorily need to acquire a DSC and register the same in the GST portal for user authentication. Other dealers can choose either the E-Sign or EVC modes. An Aadhar holder can easily do the user authentication with his/her Aadhar number by using the E-Sign option. Users can also use the EVC option, wherein, an OTP will be sent to the mobile number of the Authorized Signatory.
