ICAI Announces Migration of UDIN Portal to DigiCA Platform
ICAI will migrate its UDIN Portal to the DigiCA Platform on December 20, 2025, with a 24-hour downtime starting midnight December 19.

The Institute of Chartered Accountants of India (ICAI) has announced that it will shift its existing UDIN Portal to the ICAI DigiCA Platform on December 20, 2025.
The new DigiCA Platform will have a better design, improved ease of use, and new features as approved by the ICAI Council. This change is being made to give members a smoother and more efficient experience while using UDIN services.
To complete the migration, the current UDIN Portal will be closed for about 24 hours, starting from midnight of December 19, 2025. During this time, members will not be able to generate or verify UDINs. ICAI has advised members to create all required UDINs before the portal goes offline.
