Here is a step by step guide for those opting Aadhaar Authentication for GST registration

(1) Here is how it works:

  • The applicant is given an option to select if he wishes to authenticate with Aadhaar while applying for GST registration

  • For Aadhaar Authentication, the applicant may either select a YES or a NO.

  • If s/he clicks YES, an authentication link will be shared on GST registered mobile number and e-mail IDs of the Promoters/ Partners and Authorized Signatories.

  • On clicking the authentication link, a declaration will appear on the screen where the applicant will enter an Aadhaar number and click on "validate".

  • If the data in the application form are correctly aligned with the UAIDI an OTP will be sent to the applicant's email and mobile number registered with the Aadhaar. After entering the OTP in the box given on the validation page, a notification of successful e-KYC authentication will be shown.

  • It is necessary to ensure that a applicant's Aadhaar has an active registered mobile number and email to complete the verification expeditiously.

  • OTP would be sent on the mobile number and e-mail address registered with Aadhaar for Aadhaar authentication. You can check mobile numbers registered with Aadhaar at https:/ where the last three digits of the registered mobile number appear.

  • Where the GST registration applicant chooses not to go through the Aadhaar authentication process, he may select NO to this step. The GST application for registration will then be submitted before approval of registration to the jurisdictional tax authority which may carry out the required documentary and/or physical site verification. Where the tax authority fails to take any action within 21 days, the registration application shall be deemed as approved.

(2) How to avail the facility?

  • Log on to and navigate to Services > Registration > New Registration option.

  • Alternatively, the taxpayer can also click REGISTER NOW link.

(3) Who can do this?

The facility of quick approval of GST registration through Aadhaar authentication can be availed by all Indian citizens. However, it is not required for tax deductors, tax collectors, Online Information Database Access and Retrieval services (OIDARs), taxpayers having Unique Identification Number (UIN) and non-resident taxpayers.

In both cases, the officer concerned needs to act within a specified time - 3 days for a person opting for Aadhaar authentication and 21 days for those opting not to undergo Aadhaar authentication. If the registration application has neither been accepted, nor a notice for rejection has been issued, after the specified period, the application shall be deemed to be approved.
