GSTIN or GST Identification Number

GSTIN, known as GST Identification Number, is assigned to every GST registered person. Prior to the implementation of GST, each dealer registered under state VAT legislation was granted a unique TIN number by the individual state tax authorities. Similarly, the Central Board of Indirect Taxes and Customs granted service providers a service tax registration number (CBIC).

All registered taxpayers are merged onto a single platform for compliance and administration reasons under the GST regime and are allocated registration under a single authority.

Every firm operating in a state or Union territory will be granted a one-of-a-kind Goods and Services Tax Identification Number, or GSTIN.

Format of GSTN

The GSTIN is formatted as follows:
