## What the GSTIN By Pan API does

GSTIN By Pan returns all GST registrations associated with a PAN, along with the state and status of each.

Because every GSTIN embeds the PAN of the entity holding it, this is the most reliable way to enumerate a business's registrations. It is exact where a name search is approximate.

## Where teams use the GSTIN By Pan API

1.  Enumerating all GST registrations for a business entity
    
2.  Verifying a declared GSTIN belongs to the expected PAN
    
3.  Mapping multi-state operations during merchant onboarding
    
4.  Detecting undisclosed registrations in due diligence
    

## Frequently Asked Questions (FAQs)

Why is PAN more reliable than name?

The GSTIN contains the PAN, so the link is structural rather than a fuzzy text match.

What if a PAN has no GSTINs?

The entity is not GST registered, which may be legitimate below the turnover threshold, or may contradict what they told you.

Does it show whether each registration is active?

Yes. Status accompanies each GSTIN, so cancelled and suspended registrations are visible.
