Mobile to GST API
Find GST identification numbers linked to a mobile number, validated across government and financial registration databases.
Overview
What the Mobile to GST API does
Mobile to GST resolves a mobile number to any GSTINs registered against it, checking government and financial registration records.
For merchant onboarding this removes a form field that customers routinely get wrong. It also surfaces registrations a merchant did not mention, which is worth knowing before you set a credit limit.
