GST Registration in Bihar — Biometric Aadhaar Authentication Process (2026)
Introduction
The GST Network (GSTN) has strengthened the GST registration process by introducing biometric-based Aadhaar authentication and document verification for selected applicants as part of its risk-based registration framework. Businesses applying for GST registration in Bihar may now be required to undergo biometric Aadhaar authentication at a designated GST Suvidha Kendra (GSK) before their application is processed.
What is Biometric Aadhaar Authentication?
Biometric Aadhaar Authentication is an identity-verification process where the applicant’s Aadhaar details are verified using biometric information such as fingerprints, facial photograph or iris authentication, along with verification of original documents at a designated GSK. The objective is to prevent fake GST registrations, strengthen identity verification, reduce tax fraud, ensure genuine business registrations, and speed up registration for compliant taxpayers.
Is Biometric Authentication Mandatory in Bihar?
Applicants in Bihar may receive either an OTP-based Aadhaar Authentication link or an appointment link for biometric Aadhaar authentication and document verification at a designated GSK. The requirement depends on GSTN’s verification process and risk assessment. Those selected for biometric verification must complete it within the prescribed timeline to avoid delays.
Who Needs to Visit the GST Suvidha Kendra?
Where biometric verification is required: for a Proprietorship, the proprietor; for a Partnership Firm, the managing/authorised partner and primary authorised signatory; for a Private Limited Company, the primary authorised signatory; for an LLP, the designated partner or primary authorised signatory. The exact requirement depends on the constitution of the applicant and GSTN instructions.
Step-by-Step GST Registration Process in Bihar
Step 1 – Prepare Required Documents

Step 2 – Submit GST Registration Application
File Form GST REG-01 on the GST portal with all business details and supporting documents.
Step 3 – Aadhaar Authentication
Some applicants receive an OTP-based Aadhaar Authentication link; others receive an appointment link requiring biometric authentication at a GSK. Communication is sent to the registered email and mobile number.

Where biometric verification is required, book an appointment through the link provided, select the date and time, and save the confirmation.

After successful authentication the application is processed; additional clarification may be sought, and on approval the GST Registration Certificate is issued.
