How Many Days Does It Take to Get a GST Number?
GSTZone Desk · Updated 2026
Short answer
With Aadhaar authentication completed and no red flags, expect your GSTIN in about 7 working days. Skip Aadhaar authentication, or get flagged as risky, and it can stretch to 30 days because of a mandatory physical site visit.
In detail
Rule 9 sets the clock: once you’ve submitted a complete application with all documents in order, the officer has 7 working days to act — approve it, or raise a query — provided you completed Aadhaar-based e-KYC during the application.
If you didn’t do Aadhaar authentication, or the application gets picked up by GSTN’s risk-based data analytics as needing extra scrutiny, the process shifts to compulsory physical verification of your business premises before approval — and that can legally take up to 30 days.
In practice, the difference between a same-week GSTIN and a month-long wait usually comes down to that one checkbox at the start of the application — completing Aadhaar authentication properly the first time, with a document set that matches exactly.
GSTZone tip
Do the Aadhaar authentication step the same day you submit the application — delaying it, or fumbling the OTP step, is one of the most common reasons a straightforward application ends up in the slower physical-verification queue.
