gst invoiceA GSTIN (Goods and Services Tax Identification Number) is a unique 15-character alphanumeric code assigned to every GST-registered business in India. Verifying a supplier's or buyer's GSTIN before transactions is important to ensure they are legitimately registered, prevent fraud, and ensure you can validly claim Input Tax Credit (ITC) on purchases.
The GSTIN has a specific structure that encodes information about the business: the first 2 digits represent the state code, the next 10 characters are the PAN of the business entity, the 13th character is the entity number within the state, the 14th is Z (default), and the 15th is a check digit.
Before making a business payment or accepting a purchase invoice, always verify the supplier's GSTIN format. An invalid or fake GSTIN means you cannot claim ITC on that purchase, resulting in a direct tax loss.
