POSTFetch GSTINs by PAN

Retrieve all GSTINs linked to a given PAN — with their state and status — in a single API call.

POST/tools/kyc/gstin-with-pan

The GSTIN with PAN API accepts a PAN (Permanent Account Number) and returns a list of all GSTIN registrations associated with that PAN across every Indian state and union territory. Each entry in the list includes the GSTIN, its active/inactive status, and the state of registration. Ideal for identifying all GST registrations of a counterparty, detecting multi-state business presence, and de-duplicating vendor or merchant records during onboarding.
