GSTIN Checker — common questions
What does each part of a GSTIN mean?
The first 2 digits are the state code, the next 10 characters are the PAN, the 13th is the registration number for that PAN in the state, the 14th is usually Z, and the 15th is a check digit.
Does a valid format mean the GSTIN is active?
No. A correct format and check digit means the number is genuine-looking. Whether it is active, cancelled or suspended is shown only on the GST portal search.
Why should I check a supplier's GSTIN?
You can claim input tax credit only if your supplier's GSTIN is valid and they file their returns. A wrong GSTIN on an invoice can block your credit.
This tool gives an estimate based on the rules shown. Your actual figure depends on your full details — our expert confirms it before any filing.
