Questions people ask
What does a valid result mean?
That the GSTIN has the right 15-character shape, a real state code, a valid PAN pattern, the letter Z in the 14th place and a correct final check character. Most typing errors break the check character.
Does it tell me the GSTIN is active?
No. Only the GST portal can say whether a GSTIN is registered, active or cancelled. Use Search Taxpayer on the portal before you claim input tax credit.
How is a GSTIN built?
Two digits for the state, then the 10-character PAN of the taxpayer, then a number for how many registrations that PAN has in that state, the letter Z, and a check character.
What is the state code for my state?
Examples: 07 Delhi, 09 Uttar Pradesh, 24 Gujarat, 27 Maharashtra, 29 Karnataka, 33 Tamil Nadu, 36 Telangana. Type any GSTIN and the tool names the state for its code.
