Unused UDIN

Hey Manish,

Regarding Unused UDIN and errors:

• Once a UDIN is generated and submitted, it becomes a permanent record linked to that document and cannot be "cancelled" or "deleted" by the CA or the system.

• If you find clerical errors after 48 hours (or even earlier), you cannot simply discard the old UDIN and generate a new one for the same document.

• Correct approach:

  • Issue a revised/corrected document (like a revised audit report or certificate).

  • Generate a new UDIN for this revised document.

  • The old UDIN remains in the system but will be superseded by the corrected document’s UDIN.

• You cannot "never use" the old UDIN if it was already generated and shared with the client or authorities.

• Maintain proper documentation to explain the revision if needed during any future scrutiny.

Bottom line: UDINs are not cancellable. Mistakes require revised documents + fresh UDINs.
