The Goods and Services Tax Network (GSTN) has now enabled Biometric-based Aadhaar Authentication and Document Verification with Slot Booking for new GST registrations across all States and Union Territories, following the system’s rollout in Sikkim on May 1, 2025. This marks the completion of nationwide coverage under the mechanism, which has been implemented in line with Rule 8 of the CGST Rules, 2017.
As part of the process, GSTN uses data analysis and risk parameters to identify applicants who are required to undergo biometric Aadhaar authentication and in-person verification of documents submitted during the GST registration process.

Biometric authentication and verification will be carried out at the GSK for all individuals listed in the application. The applicant must complete this process within the maximum permissible period specified in the email. Upon successful completion, the system will generate an Application Reference Number (ARN).
The slot booking feature for applicants in Sikkim went live on May 1, 2025, making the functionality available pan-India, across all 36 States and Union Territories—including Delhi, Gujarat, Maharashtra, Kerala, Tamil Nadu, West Bengal, and the Union Territories of Ladakh, Lakshadweep, and the Andaman & Nicobar Islands.
