The Unique Document Identification Number (UDIN) is a system introduced by the Institute of Chartered Accountants of India (ICAI) to help identify and verify documents certified or attested by practising Chartered Accountants.
What UDIN is
UDIN is a number generated on the ICAI’s UDIN portal for documents that a Chartered Accountant certifies, attests, or signs in practice. Once generated, the number is mentioned on the document so that the recipient can confirm that it was issued by a member of the Institute.
Why it matters
- Authenticity: Regulators, banks, and other stakeholders can verify, through the UDIN portal, that a certificate or report was genuinely issued by a Chartered Accountant.
- Traceability: It links the document to the member who issued it.
- Confidence: It reduces the risk of forged or falsely attributed certificates.
How verification works
Any recipient of a document can visit the ICAI UDIN portal and enter the UDIN to confirm the basic details of the document and that it was issued by a member in practice.
Our practice
All certificates and reports issued by the firm carry a UDIN as mandated by ICAI.
