Retrieve every GSTIN registered against a PAN and check each one's status — turning a single PAN into a complete view of a business's GST footprint.
Overview
What the PAN to GST API does
FinHub's PAN-to-GST API returns all GST registrations linked to a business PAN, with the legal name, state and registration status of each. It's a fast way to confirm a business is real and GST-active during onboarding, reconcile the GSTINs a counterparty actually operates, and flag mismatches between the PAN, the entity name and its tax registrations — sealed to your audit trail.
