What is GSTIN?

GSTIN, short for Goods and Services Tax Identification Number, is a unique 15-digit PAN-based identification number allocated to every registered taxpayer under the GST system. Obtaining a GSTIN becomes mandatory when a person crosses the threshold limit for GST registration and registers under GST. Unlike the previous indirect tax regime, where different registration numbers were present for different tax laws such as Excise, Service Tax, and VAT, GSTIN is a single registration number for all under GST.

Every state or Union Territory from which the registered person operates may have a separate GSTIN. The first two digits of the GSTIN represent the state code of the registered person, followed by ten characters representing their PAN number, then an entity number of the same PAN, the letter Z by default, and finally, a check code to detect errors.
