GST
GSTIN (Goods and Services Tax Identification Number)
Unique 15-digit registration number assigned to every GST-registered business.
Full Definition
GSTIN is a 15-digit alphanumeric code assigned to every GST-registered person in India. Structure: 2-digit state code + 10-digit PAN + 1-digit entity code + 1-digit check digit. Every registered supplier must display GSTIN on their premises and mention it on invoices. GST returns (GSTR-1, GSTR-3B) are filed using GSTIN. A business can have multiple GSTINs — one per state/UT where they have a business presence.
