ICAI UDIN- An Advance Solution for Document Verification

Monday, July 9, 2018

What is UDIN?

The Professional Development Committee (PDC) of ICAI has introduced Unique Document Identification Number (UDIN) for documents attested & certified by Chartered Accountants.

UDIN is a unique number, which will be generated by the system for every document certified/ attested by a Chartered Accountant and registered with the UDIN portal available at https://udin.icai.org/

A practising Chartered Accountant can generate a UDIN for certificate/ document attested by him either in individual capacity or as a partner. The Certificate Number can be cross checked at https://udin.icai.org?mode=searchudin & there is no restriction on the number of UDINs to be generated by a CA.


It has been noticed that financial statements and documents were being certified/ attested by third persons, in lieu of Chartered Accountants. As these statements are being relied upon by the authorities as true statements and certificates, UDIN can be generated by a practicing CA by registering his/her documents/ certificates on UDIN Portal for verification.

At present, this facility is recommendatory. But ICAI is mulling to make the same compulsory in near future, so as to curb the menace of fake or forged documents.

For any assistance/ clarification on UDIN, CA members can contact at (011) 30110444 or email at udin@icai.in
