## What the GSTIN By Name API does

GSTIN By Name searches GST registrations by business name and returns the GSTINs found, including registrations across multiple states.

Businesses operating in more than one state hold a separate GSTIN per state. Seeing them together gives an accurate picture of the operation's real footprint, which a single number never shows.

## Where teams use the GSTIN By Name API

1.  Finding a GSTIN when only the business name is known
    
2.  Mapping a group's registrations across states
    
3.  Checking whether a business is GST registered at all
    
4.  Detecting similarly named entities before onboarding
    

## Frequently Asked Questions (FAQs)

Why does one business have several GSTINs?

GST registration is state-wise, so a business operating in several states holds one GSTIN in each, all linked to the same PAN.

How exact must the name be?

Matching tolerates variation, but the legal name often differs from the trade name customers use. Try both if the first search comes up short.

Can I search by PAN instead?

Yes. GSTIN By Pan returns all GSTINs linked to a PAN, which is usually the more reliable route.
