GSTIN is a 15-digit identification number issued by the tax department upon successful processing of your application.

Decoding the GSTIN will give us the following information:

  • The first two digits represent the state code.
  • The next ten digits represent the PAN number of the business owner.
  • The next two digits represent the entity code of the PAN holder in a state.
  • The fifteenth digit is the checksum digit.
