For example, an audit report issued by the auditor with respect to the financial statement of an entity regarding its financial statements reflecting a true and fair view of the state of affairs of the entity. It is because of this attestation or signature made by the Chartered Accountant that the investors and other stakeholders can rely upon the performance of an entity.
What is a Unique Document Identification Number (UDIN)?
Unique Document Identification Number (UDIN) is an 18-Digits system generated unique number for every document certified/attested by Practicing Chartered Accountants.
Applicability of UDIN
How did UDIN come into play?
The ICAI introduced a unique Idea in the form of UDIN, Unique Document Identification Number, for controlling the malpractice of Non-CAs who impersonate as CAs working for the industry, which was implemented in phases.
The UDIN will secure certificates, reports, and documents attested or certified by practicing CAs, providing a window to regulators, banks, and third parties for verifying their authenticity. This will add credibility and trust to the certification process.
What is the Format of UDIN?
The 18- digits UDIN (YY MMMMMM AANNNAANNN) will be like;
19304576AKTSBN1359
Wherein;
First 2 Digits are YY - Last 2 digits of the Current Year (19 in this case)
Next 6 Digits are MMMMMM – ICAI’s Membership No. (304576 in this case)
Next 10 Digits are AANNNAANNN –Alpha-numeric generated randomly by the system (AKTSBN1359).
