GSTIN Validator
Check the format and check digit of any GST number. See the state, PAN and entity type inside it.
What does this tool check?
It checks the GSTIN structure (state code, PAN pattern, entity number, letter Z) and the final check digit. It does not tell whether the registration is active. To confirm that, use Search Taxpayer on the GST portal (gst.gov.in).
How is a GSTIN made?
Characters 1-2: state code. 3-12: PAN of the taxpayer. 13: number of registrations under that PAN in the state. 14: the letter Z. 15: check digit.
