The GST number is a unique identifier for any GST registered business or taxpayer. Popularly known as the GSTIN (Goods and Services Tax Identification Number), it’s a 15-digit code that can be used to track transactions, make payments, file GST returns, claim Input Tax Credit and maintain overall GST compliance.
