PAN and GST Linkage

Having a GST registration / number becomes mandatory once you exceed a certain revenue for your business. 


These GST numbers for a  business are registered using a business’ / owners PAN card. But ensuring a certain PAN is linked to a specific GST number becomes an important step in ensuring a non-fraudulent merchant / user journey.


IDfy’s PAN and GST linkage API allows you to find, verify and fetch the details of all GST numbers linked to a specific PAN number.
