Any document or certificate with a chartered accountant’s attestation possesses prodigious value. It typically denotes no misrepresentation from an entity while issuing such a document.

This brings possibilities to replicate signatures of CAs to issue such documents and certificates. Therefore, ICAI introduced a unique document identification number to secure a document authenticated by a CA.

UDIN portal generates a unique number for every document or certificate attested by a chartered accountant. A chartered accountant must register on the portal for UDIN verification.
