How is this different from GST verification?

GST verification validates a known GSTIN. PAN-to-GST works the other way: from a PAN, it discovers all the GSTINs a business holds, useful when you only have the PAN at onboarding.

Is it useful for fraud detection?

Yes. Mismatches between the PAN, the entity name and its GST registrations, or unexpectedly inactive registrations, are strong signals to pause and review a business.

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.
