What the GSTIN Verification API does

A GST number on an invoice proves nothing until it is checked. The GSTIN Verification API confirms the registration is active, tells you exactly who it belongs to, and reveals whether the business is filing returns on time, the single most useful early indicator of a healthy counterparty.

Supply an expected company name and the API compares it with the registered legal and trade names, so mismatched or borrowed GSTINs are flagged before a purchase order is raised.

Inactive, cancelled or borrowed GSTINs are caught before the first invoice.

Filing health at a glance

Late or missing returns are a practical early warning about a supplier.

Name comparison

Legal and trade names come back separately so procurement can reconcile invoice headers.

Real-time

Fits inside vendor self-registration portals and procurement approval flows.

GSTIN Verification API: frequently asked questions

What teams ask before adding the GSTIN Verification API to their integration.

A summary of whether recent GST returns have been filed, which helps procurement and credit teams gauge how well run the business is.

Yes. Use the GSTIN by PAN API to list every registration held against the company's PAN across states.

It is the essential first step. For a complete picture, pair it with the MCA company lookup, directorship lookup and bank account verification, all available on the same API key.
