UDIN: ICAI defers the deadline

Today, ICAI announced that the mandatory use of UDIN has been deferred to 1st Feb 2019. The earlier date was 1st Jan 2019.  ICAI has mentioned that it has engaged TCS for automating the members’ database and life cycle details. The huge data migration and data audit will take around 30 days before the UDIN Platform becomes mandatory. Hence, Central Council of ICAI has decided to mandate UDIN w.e.f 1st February, 2019 in a phased manner as against the earlier announced date of 1st January 2019.

What is UDIN?

UDIN or Unique Document Identification Number is a unique number that will be generated on the UDIN portal for every certificate and other such documents that have been attested by a Chartered Accountant. Every Chartered Accountant (practicing CA) has been mandatorily required to register themselves on the ICAI portal. After that, they need to generate a unique id for every document that is to be attested by them.

UDIN can be generated by the Chartered Accountants only via the UDIN portal and the validity of the attested document can be checked by the authorities.


UDIN is an initiative taken by ICAI to curb misrepresentation.  Some people pose as Chartered Accountants and forge signatures on documents to mislead authorities. With the use of UDIN;  banks, RBI, Income Tax Department, etc. can check the validity of the documents issued by the Chartered Accountant.  The authorities can quote the unique identification number and verify the Firm Registration Number (FRN), Client Reference Code, Date of Document, etc. through the UDIN portal. This will confirm the authenticity of the documents attested.

How to generate UDIN?

In order to generate UDIN, the members need to first register themselves on https://udin.icai.org. To register or Sign-up, they need six-digit
Membership No., Date of Birth and Date of Enrollment. The sign-up process is authenticated with OTP that will be received on the mobile number and e-mail address registered with ICAI.

After successful login, the member should click “Generate UDIN”.  The member is required to fill in details like Membership Registration Number, Name, E-mail ID, Firm Registration Number, Firm Name, Client Reference Code / Number, Document Description, Date of Document, Keywords, and values, etc. This process will also be authenticated by an OTP. Members should note that once the data is submitted for generation of UDIN, it cannot be deleted or modified. Therefore, all the entered details should be carefully checked before submission.

Some unique features of UDIN

⇒ UDIN that have been generated would be displayed as watermarked on documents else the UDIN can be mentioned on the documents using a pen. (Check “List UDIN” menu to print the UDIN.)

⇒ UDIN that have been generated can be searched using various criteria. For eg: UDIN, FRN, Client Reference Code, Document Issued Under, Date of Document and Document Status. (Check “Search” menu to search the UDIN).

⇒ UDIN once generated can be withdrawn or cancelled with narration. On search of such revoked UDIN, appropriate narration mentioned by the member along with the date of revoking the UDIN, will be displayed for reference. (Check“List UDIN” menu to revoke the UDIN.)
