Rule 8 of the CGST Rules, 2017 has been amended to enable applicant identification via Biometric-based Aadhaar Authentication and document verification on the common portal. This functionality, rolled out by GSTN in Kerala, Nagaland, and Telangana on October 5, 2024, allows applicants to receive an email after submitting Form GST REG-01 with either a link for OTP-based authentication or a link to book an appointment for biometric verification at a GST Suvidha Kendra (GSK). If the OTP link is received, applicants can proceed with the existing application process.
