UDIN Generation Update: UDIN Generation Now Requires Extra Detail
The Unique Document Identification Number (UDIN) is an 18-digit number that is generated for every document that is certified or attested by Chartered Accountants (CAs). Only the CAs with a full-time certificate of Practice can generate UDIN. The unique number has been made mandatory for all types of Certifications, GST and Tax Audit Reports and other Audit, Assurance and attestation functions signed by a full-time Practising CA.
It was introduced after several complaints were received by ICAI that the documents were being attested by non-CAs who were impersonating themselves as CAs. Therefore, to prevent such practices, ICAI brought in the system of UDIN. It secures the certificates or reports, or documents attested or certified by practising CAs. Additionally, the third-party entities, such as regulators and banks, can also verify the authenticity of such documents.
The Institute of Chartered Accountants of India has brought a significant change in the UDIN generation under the categories ‘GST & Tax Audit‘ and the ‘Audit & Assurance Functions‘. While generating the UDIN, CAs need to enter details like membership number, client reference code, etc. Now, the Chartered Accountants (CAs) are mandatorily required to give information about the Auditor’s Opinion at the UDIN portal while generating UDIN. The auditor’s opinion is a statement given by the external auditor regarding the level of accuracy of the financial statement of a company. However, the third-party verifiers cannot access this information.
