GSTIN validation moves to live registry lookup
GSTIN validation on customer and vendor records now performs a live registry lookup instead of a format check. The returned registered legal name, trade name, state code, registration type and current status are written onto the party with a last-checked timestamp, and a mismatch against the name you typed is flagged. The state code feeds place-of-supply logic on every document raised for that party, so a wrong registration is caught before it produces a run of wrongly taxed invoices.
