Applicability

ICAI has mandated all CA in practice to obtain UDIN for all the certificates issued by them if the Financial information or any other content is certified as depicting a True and Fair view. The CA firms cannot register themselves on the UDIN portal. Chartered Accountants having full-time Certificate of Practice can register on UDIN Portal and generate UDIN by registering the certificates attested/certified by them.

UDIN is being made mandatory from 1st July, 2019 on all Corporate/ Non- Corporate Audit, Attest and Assurance Functions.

The UDIN generated by CA can be searched in online UDIN portal through search option by giving the Name, Contact and Email id of the person requesting the information.This will ensure the authenticity of the documents being certified by the CA members and can be relied upon by Stakeholders, Banking and various other regulating authorities.

• The next 10 digits are alphanumeric digits randomly generated by the system

When the CA in practice has to generate UDIN?

The UDIN has to be generated within 15 days from the date of signing or attesting the documents by the CA in practice and it cannot be done beyond 15 days from the date of signing.

Limit on generation of UDIN

Precautions while generating UDIN and signing documents
