ICAI – UDI number to be generated for all certificates issued by Chartered Accountants – Presently Optional

Time and again, various authorities across the country have reposed their faith in chartered accountants as professionals realising the work of their attributes like Integrity, Excellence and Independence.  Based on the same, they are relying on various certifications being issued by chartered accountants in practice in the normal course of business. They look upto Chartered Accountants as reliable source of authentic information and to ensure compliance with various rules, regulations, procedures stipulated under different statutes.


However, many instances have been brought to our attention wherein financial statements and certificates issued either by nonmembers or members not holding Certificate of Practice have been relied upon by authorities as true statements and certificates. It needs no reiteration that a certificate issued by a practicing chartered accountant binds him to its accuracy and subject him to Disciplinary Proceedings of the Institute, in case a complaint in that regard is filed with the Institute by the concerned authorities (or any affected party).

UDIN is a maximum 32 character Unique Document Identification Number which will be issued to every document certified/attested by a Chartered Accountant and registered with the Institute of Chartered Accountants of India (ICAI).
