What is Goods and Services Identification Number (GSTIN)?

It is completely free to obtain a Goods and Services Tax Identification Number and to register for GST. Prior to the introduction of GST, all dealers were required to register under state VAT laws, which provided them with a unique TIN number issued by the state’s tax authorities; the Goods and Services Tax Identification Number has since replaced this. The GSTIN is a unique identification number provided to businesses that register under the GST regime.
