Supplier GSTIN Risk Quick-Scan
Upload your supplier list and see, in seconds, which GSTINs have a format or check-digit problem, which are repeated, and which do not match the State you listed. Whether a supplier is active or files on time is not checked here: look each one up with Search Taxpayer on the GST portal.
How this works
- Paste or upload a CSV or plain-text list, up to 200 suppliers. A header row with GSTIN, Supplier, State and ITC columns is optional.
- We check each GSTIN's pattern and check character, flag repeats, and compare the State code in the GSTIN with the State you listed.
- We do not guess whether a supplier is risky. Cancelled, suspended and late-filing status is not checked here: look it up with Search Taxpayer on the GST portal.
- Your list is checked and sent back to you. In this mode it is not stored.
About this tool
- What it does
- Runs the GSTIN format test on a whole supplier list, flags repeated GSTINs and compares each GSTIN’s State code with the State you listed for that supplier.
- The rule it rests on
- Input tax credit depends on the supplier, not only on your invoice: under section 16(2) of the CGST Act, 2017 the credit is available only where the supplier has furnished the invoice in its outward return and the tax has been paid to the Government. The scan checks the numbers themselves; a supplier’s filing record is read on the GST portal. Official source: CGST Act, 2017, section 16 (eligibility and conditions for input tax credit)
- Checked on
- 10 November 2026. Where a figure the tool shows is still to be verified by our expert team, the tool says so instead of showing it.
- Next step
- Upload your GSTR-1, GSTR-3B and GSTR-2B and see where the figures in your returns do not agree. GST health check on your returns
