Bulk Verification

What is Bulk GSTIN Verification?

Bulk GSTIN verification lets you validate hundreds of GST numbers in one go — instead of checking each GSTIN one by one on the official GST portal. GSTVerify queries the GSTN API in parallel, returning real-time status, legal name, and taxpayer type for every entry in your list within seconds.

Businesses use bulk verification to screen new suppliers before onboarding, audit vendor lists before filing GSTR-2A reconciliation, and detect cancelled or suspended registrations that could block ITC claims.

Why Bulk Verify Matters for ITC

Under GST rules, Input Tax Credit is available only if your supplier's GSTIN is active and they have actually filed their returns. Transacting with a supplier whose registration has been cancelled or suspended can result in ITC denial, penalties, and notices from your GST officer. Bulk verification before each purchase cycle is the simplest way to protect your ITC.

• A single cancelled-GSTIN purchase can trigger a demand notice for the full ITC amount plus 18% interest.
• GSTR-2B auto-populates only invoices from active, filing suppliers — inactive GSTINs won't appear.
• Rule 36(4) restricts provisional ITC to 105% of GSTR-2B amounts — unmatched invoices count against you.

How GSTVerify Bulk Lookup Works

GSTVerify uses server-side parallel cURL requests to fetch all GSTINs simultaneously from the GSTN API, rather than sequential one-by-one calls. Cache hits return instantly (no API call needed). New GSTINs are fetched in parallel, typically completing a 50-GSTIN batch in under 5 seconds.
