Migration of UDIN Portal to ICAI DigiCA Platform

The members are hereby informed that the Institute of Chartered Accountants of India (ICAI) is contemplating migration of the existing UDIN Portal to the ICAI DigiCA Platform on 20th December 2025. The upgraded system will provide improved interface, better usability and enhanced features in line with the various decisions of the Council.

To facilitate the migration, the existing UDIN Portal will remain unavailable for UDIN related activities (generation/ verification) during the transition window for around 24 hours, i.e. with effect from the midnight of 19th December, 2025.

Members are advised to generate all required UDINs prior to the scheduled downtime.

A comprehensive User Manual will be made available on the new platform for the guidance of members.

In addition, a dedicated UDIN Mobile App, both on IOS and Android platforms, will be launched on 30th December 2025, to provide convenient mobile access for members.

For queries, please write to us at udin[at]icai[dot]in.
