GSTINGST
GST Identification Number
(GSTIN)
Definition
A 15-digit unique identification number assigned to every GST-registered business. The first 2 digits are the state code, next 10 are the PAN, followed by entity code and check digit.
Why founders care
Your GSTIN must appear on all tax invoices. B2B clients will ask for this before they pay you — without it they cannot claim input credit.
