Overview

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.
