Unique Document Identification Number


The Unique Document Identification Number (UDIN) is a unique identification number generated by the Institute of Chartered Accountants of India (ICAI) for every document certified or attested by a practicing chartered accountant. It serves as a way to verify the authenticity and integrity of the documents and to prevent fraudulent practices.

The UDIN system was implemented by the ICAI to enhance transparency, accountability, and credibility in the attestation and certification of documents by chartered accountants

The UDIN is a 15-digit alphanumeric number that is generated online through the ICAI's portal. It is linked to the digital signature of the chartered accountant and contains information such as the membership number, date of attestation, and the document's details
