Unique Document Identification Number (UDIN)

What is Unique Document Identification Number (UDIN)?

The Unique Document Identification Number (UDIN) is a unique identification number generated for every document certified or attested by Chartered Accountants in practice. This system was introduced by the Institute of Chartered Accountants of India (ICAI) to enhance the authenticity and traceability of the documents and reports certified by CAs. It is designed to prevent fraudulent practices by ensuring that the documents presented by third parties are genuinely attested by a practicing Chartered Accountant.

Each UDIN consists of a 15-digit number that is automatically generated by the UDIN portal. This number includes details such as the membership number of the Chartered Accountant, the date of document issuance, and a randomly generated number. Once a UDIN is generated, it can be used by regulators, banks, and other stakeholders to verify the authenticity of the document by checking it against the UDIN portal.

1. Need for Introduction of UDIN

Chartered Accountants (CAs) have an important role in the economic development of the country and the Institute of Chartered Accountants (ICAI) being the governing body has a very crucial role to play as a partner in the process of nation building. Before the introduction of Unique Document Identification Number (UDIN) in 2019, there was a huge demand from the Indian Banker’s Association (IBA) and the bankers regarding the verification of authenticity of the signature of Chartered Accountants (CA). ICAI noticed rising cases of misrepresentation of CAs’ services and forged signatures of CAs being done by non-CAs.

It was to fulfil this demand and curb such malpractices, that ICAI came up with the idea of online real time processing system wherein the credentials of any of its members could be verified. So, it was from the genesis of idea that UDIN was initiated. UDIN is amongst the most successful reforms ICAI has undertaken in the recent past. Accordingly, ICAI has come up with a guideline that every signature of the CA must be followed by a UDIN, in order to establish the ownership of that particular document. The advent of UDIN has helped establish a climate of trust, accountability and openness among the stakeholders towards ICAI and its members.
