About this API

Many small enterprises still present their UAM certificate. This API verifies it against the registry and returns the recorded details so MSME onboarding is not blocked by the migration.

Typical uses

MSME lending. Verify registration for scheme eligibility.
Marketplace seller onboarding. Registered small businesses only.

Questions

Should I call Udyam or Udyog Aadhaar?: Udyam for numbers starting UDYAM-; Udyog Aadhaar for the older UAM format. Both return the same canonical fields.
