About this GSTIN Validator
A GSTIN is 15 characters: state code, the PAN of the taxpayer, an entity number, the letter Z and a check character. The tool tests that structure and the checksum and tells you the state and the holder type taken from the PAN.
A correct format does not prove the GSTIN is active. Confirm registration status, legal name and filing history on the official GST portal before claiming input tax credit.
