Rule 8 of the CGST Rules allows the GST portal to pick some registration applicants, based on data analysis and risk, for biometric Aadhaar authentication, a photograph, and checking of original documents at a GST Suvidha Kendra (GSK). The process is now in place across the country.
After you submit REG-01
You receive one of two emails:
- A link for OTP-based Aadhaar authentication. Complete it online and carry on as normal.
- A link to book a GSK appointment, with the GSK's details and your jurisdiction, for biometric authentication and document checks.
If you're called to a GSK
- Book a slot using the link in the email.
- You'll get an appointment confirmation email.
- Visit the GSK at your chosen time and carry:
- the appointment confirmation (paper or on your phone)
- the jurisdiction details from the intimation email
- original Aadhaar and PAN cards
- the originals of the documents you uploaded with the application
Who has to go
- Promoters/partners who chose Aadhaar authentication go for biometrics and a photo.
- The Primary Authorised Signatory (PAS) also goes for biometrics and a photo, and brings the documents for checking.
- Already verified before? A promoter or partner verified biometrically for an earlier registration in any State/UT doesn't need to go again for another business. If they're the PAS of the new business, only document verification is needed.
- Not opting for Aadhaar authentication at all? You must visit the GSK for a photo and document checks.
Option for company directors
Promoters or directors of public, private, unlimited and foreign companies can choose any GSK in their home State (as given in REG-01) instead of the one linked to the business's jurisdiction. The choice is made once through the email link and can't be changed.
Tips
- Book your slot quickly so you don't miss the processing deadlines.
- Take the originals of everything you uploaded, as copies may not be accepted.
- Make sure the details in REG-01 exactly match your documents.
