GSTIN (India)
Overview
A Goods and Services Tax Identification Number (GSTIN) is a unique 15-digit identifier assigned to businesses registered under India’s Goods and Services Tax (GST) system. It is issued by the Goods and Services Tax Network (GSTN) and is mandatory for entities involved in the supply of goods or services above a specified turnover threshold. The GSTIN structure encodes details such as the state code, PAN of the business, and a registration number.For banks, fintechs, lending platforms, and regulators, GSTIN is widely used in Know Your Business (KYB) verification, tax compliance, and fraud prevention. It enables quick validation of a business’s legitimacy, registration status, and tax filings. Automated GSTIN verification APIs are commonly integrated into onboarding workflows to confirm authenticity and detect discrepancies. Accurate GSTIN checks improve trust in B2B transactions, reduce risks of shell entities, and support regulatory compliance in India’s digital economy.
