The Institute of Chartered Accountants of India (ICAI) has announced a crucial update regarding the generation of Unique Document Identification Numbers (UDIN). With immediate effect, members will now be required to mandatorily provide details of the Auditor's Opinion while generating UDINs under the categories of 'GST & Tax Audit' and 'Audit & Assurance Functions'.
This move aims to enhance the accuracy and integrity of audit documentation submitted through the UDIN portal, which serves as a safeguard against document forgery and enhances stakeholder confidence.

Official copy of the notification is as follows
Additional information required during UDIN generation under 'GST & Tax Audit' and 'Audit & Assurance Functions' Categories
The members are hereby notified that the information regarding Auditor's Opinion, henceforth, would be required to be filled in, while generating UDIN under 'GST & Tax Audit' and 'Audit & Assurance Functions' categories at the UDIN portal.
The information regarding Auditor's Opinion is mandatorily to be provided at the UDIN portal during the generation of UDIN. The information so filled in by the members would thus not be visible to any third-party verifiers.
Members may take a note of aforesaid information.
