The process of GST registration requires applicants to complete verification steps based on their choice of Aadhaar authentication. The GST Suvidha Kendra (GSK) plays a crucial role in verifying identity and documents for those who opt out of Aadhaar authentication.
Understanding GST Registration via GSK
The Goods and Services Tax (GST) is mandatory for businesses exceeding the prescribed turnover threshold. The government offers two verification routes:
Aadhaar Authentication – Faster processing with online verification.
Non-Aadhaar Authentication – Requires an in-person visit to GSK for verification.
Applicants must be aware of the steps involved in both methods to ensure a smooth GST registration process.
Steps for Applicants NOT Opting for Aadhaar Authentication
If you do not opt for Aadhaar authentication, you must complete physical verification at a GST Suvidha Kendra (GSK). Here’s what you need to do:
- After submitting Part B of REG-01, you will receive an email notification with details of the nearest GSK location and a list of required documents.
- Use the link in the email to schedule an appointment.
- A confirmation email will be sent once the appointment is successfully scheduled.
- Visit the GSK on the assigned date and time for photo capturing and document verification.
Failure to visit the GSK within 15 days will lead to the rejection of your GST registration application.
Steps for Aadhaar Authentication & Biometric Verification
If you choose Aadhaar authentication, certain applicants may be required to complete biometric verification.
Who Needs to Visit the GSK for Biometric Authentication?
- Promoters/Partners who opt for Aadhaar authentication must visit the GSK for fingerprint/iris scan and photo capture.
- The Primary Authorized Signatory (PAS) must visit the GSK for biometric authentication and document verification.
- If a Promoter/Partner has already completed biometric verification in any State/UT, they do not need to repeat it. However, if they are designated as PAS, they must still undergo document verification.
- If a PAS has already been biometric verified previously, only document verification at GSK is required.
- If an applicant is both a Promoter/Partner and the PAS, they must undergo photo capture, biometric authentication, and document verification unless biometric verification was completed earlier. In such a case, only document verification is required.

What Causes Non-Generation of ARN (Application Reference Number)?
An Application Reference Number (ARN) will NOT be generated if:
- The applicant fails to visit the GSK within 15 days after submitting Part B of REG-01.
- Biometric authentication is unsuccessful or document verification remains incomplete.
- Aadhaar details do not match (name, date of birth, gender discrepancies).
To prevent application delays, ensure that all Aadhaar details are accurate before submitting your GST registration request. If there’s a mismatch, update your Aadhaar details and complete verification within 15 days.
