GST registration documentary limits: officers must accept prescribed proofs and refrain from seeking non prescribed documents, ensuring timely approval. Officers must limit documentary demands to the indicative list in the registration form and avoid presumptive or non prescribed queries. For Principal Place of Business, any one listed ownership document or equivalent state/local proof suffices for owned premises; rented/shared premises require rent/lease agreements plus a single lessor ownership document, with identity proof needed only where the lease is unregistered. Constitution of business must be established by prescribed constitution documents only. Risk flagged or unauthenticated applications may require physical verification, with prescribed reporting and upload requirements; formal notices may be issued only on limited documented grounds.
