Many times it has been noticed that non-CAs has been misrepresenting themselves as CA member and providing certification services to various Authorities and Stakeholders. Such malpractices started bringing a question on the genuineness of financial documents/certification done by actual CA Members in practice.

Seeing an increase in a number of complaints received by ICAI, the Professional Development Committee of ICAI has come out with an innovative concept of UDIN i.e. Unique Document Identification Number.

What is UDIN :

Unique Document Identification Number (UDIN) is 18-Digits system generated unique number for every document certified/attested by Practicing Chartered Accountants. It will enable various Stakeholders and third parties to check the authenticity of the documents and will secure the certificates attested/certified by practising CAs.

Applicability of UDIN :

From 1st February 2019 it is mandatory for all practising Chartered Accountants to generate and obtain UDIN for all Certificates issued, containing financial information or any other contents; which are certified by them to be True and Fair or True and Correct.

UDIN cannot be generated in name of Firm and has to be obtained only by practising CAs holding full time COP. In case of Partnership firm or LLP, signing partner has to generate UDIN in his name. No other partner can obtain UDIN instead of signing partner.

UDIN is applicable not only to manually signed certificates but it also applies to digitally signed / online certificates.

Practising CAs holding full-time COP has to follow the Guidance Note on Reports or Certificates for Special Purposes (Revised 2016) issued by AASB (Auditing and Assurance Standard Board) of ICAI.

Though practising Chartered Accountants have to generate and obtain UDIN for all certificates, following are list of certificates for which UDIN is not made mandatory :

  • Auditor's Opinion/Reports issued under any Statute to any entity or any person (e.g.: Tax Audit, Transfer Price Audit, VAT Audit, GST Audit, Company Audit, etc.,)
