Unique Document Identification Number (UDIN)

About UDIN

The concept of UDIN (Unique Document Identification Number) is proposed to curb the malpractices of misleading the Authorities and Stakeholders by non-CMAs misrepresenting themselves as CMAs and attesting the Costing Data / documents / certificates. . .


Authorities / Regulators / Banks / Others

Authorities / Regulators / Banks / Others can verify the UDIN through this web portal giving few details like name of person, mobile no, and email etc.




This UDIN System has been developed by The Institute of Cost Accountants of India to facilitate its members for verification and certification of the documents and for securing documents and authenticity thereof by Regulators. However, The Institute assumes no responsibility of verification and certification of document(s) carried out by the Members and the concerned member(s) shall alone be responsible therefore.
