Coming soon: upload a CSV of GSTINs and get every one verified in a single run — status, legal name, state and mismatch flags in a downloadable report. How bulk verification will work Prepare a CSV. One GSTIN per row is enough; optionally include the vendor name from your ledger and any internal vendor code so the report maps straight back to your books. Upload and run. Every number is checksum-validated first — malformed rows are flagged immediately and cost you nothing — then each valid GSTIN is checked against GSTN registration records. Download the report. One row per GSTIN: status (Active / Cancelled / Suspended), legal name, trade name, state, registration date, plus a name-match column comparing the registered legal name against the vendor name you supplied. Until the tool ships, single lookups remain free and unlimited within fair use — start with GST verification for one supplier at a time. The reconciliation use case The monthly grind every accounts team knows: the purchase register lists hundreds of vendor GSTINs, and your input tax credit depends on each one being genuine and active in the relevant period. Checking them one by one on a portal is hours of copy-paste. Bulk verification turns it into one upload — and the interesting output is not the long list of green rows, but the short list of exceptions: the GSTIN that went Suspended last quarter, the vendor whose registered legal name does not match your ledger entry, the typo that fails the checksum and explains why a credit never reconciled. ITC at risk: why this is worth automating Input tax credit claimed against a cancelled or fake GSTIN does not just disappear quietly — it comes back as a demand with interest, and disputes consume far more time than prevention ever would. Even a mid-sized trading business can have lakhs of rupees of ITC riding on its vendor list in any given quarter. A periodic bulk check is the cheapest control available: it converts “we assume our vendor master is clean” into a dated report that says so. Pair it with the onboarding checklist on the GST verification page and the status guide on GST number check , and vendor GST risk becomes a managed process rather than a year-end surprise.

The free tier will cover small lists, with larger batches and scheduled re-verification available on a paid plan. Multi-state vendors will be grouped by PAN in the report (the same grouping you can explore today with GST search by PAN ), and each row will link to the full single-GSTIN result. Want early access?

CSV to begin with — the export format every accounting package and spreadsheet already produces. A simple one-column file of GSTINs works; extra columns like vendor name and vendor code are carried through to the report. No. Every GSTIN is validated against the format and check digit rules first (see the GST number format guide ); rows that fail are flagged as typos without ever hitting a live lookup. The same freshness rules as single lookups apply: recently fetched records come from cache with a timestamp, others are pulled live from GSTN records via authorised APIs. Our data sources page describes the caching windows honestly. Hold new payments to them, confirm the cancellation or suspension date against your invoice dates, and take the specific steps listed in the status table on the GST number check page .
