Questions people ask
Does a valid format mean the business is registered?
No. This checks the structure and check digit only. To confirm a registration is active and see the legal name, use 'Search Taxpayer' on the official GST portal (gst.gov.in).
What does each part of a GSTIN mean?
Characters 1 and 2: state code. 3 to 12: the business's PAN. 13: the registration number for that PAN in the state. 14: Z by default. 15: a check digit calculated from the first 14.
