Bulk GSTIN verification

How bulk verification works here

Paste one GSTIN per line, or a column copied from a spreadsheet. Each number is first checked for structure — length, state code, PAN segment and checksum — and only well-formed numbers are sent for a live lookup, so obvious typing errors do not consume a lookup. Results are written back row by row, in the order you supplied them, and can be downloaded as CSV for your records.

What each row tells you

A completed row shows the legal name on the registration, the current GST status, and the state of registration. A row can also come back without a record: that usually means the number is well-formed but is not a live registration, and it deserves a query to the supplier rather than an assumption.

Practical uses

Cleaning a supplier master before a filing period, checking a new vendor list during onboarding, or re-checking existing counterparties periodically, since a registration that was active last quarter can since have been cancelled or suspended.

Limits and caveats

Runs are capped to keep lookups fair for everyone, and a job needs an account so results stay attached to you. Details reflect what the lookup returned at that moment and may be served from a recent cached result — read how we source and refresh data before relying on a run for a filing or payment decision, and confirm anything consequential on the official GST portal.
