Why is multi-state GST registration detection important?

A single PAN can have GST registrations in many states. Detecting all of them helps enterprises verify vendor compliance, consolidate tax records and flag shell entities with suspicious registration patterns.

Who uses the PAN to GST lookup API?

B2B marketplaces, enterprises running vendor due diligence, credit underwriters and tax-tech platforms use it to map complete GST footprints of businesses.
