The Institute of Chartered Accountants of India

Unique Document Identification Number (UDIN) is 18-Digits system generated unique number for every document certified/attested by Practicing Chartered Accountants.

It has been noticed that financial documents/ certificates attested by third person misrepresenting themselves as CA Members are misleading the Authorities and Stakeholders. ICAI is also receiving number of complaints of signatures of CAs being forged by non CAs.

To curb such malpractices, the Professional Development Committee of ICAI has come out with an innovative concept of UDIN i.e. Unique Document Identification Number which is being implemented in phased manner. It will secure the certificates attested/certified by practicing CAs. This will also enable the Regulators/Banks/Third parties to check the authenticity of the documents.

The 18- digits UDIN (YY MMMMMM AANNNAANNN) will be like;

19304576AKTSBN1359

Wherein;

First 2 Digits are YY - Last 2 digits of the Current Year (19 in this case)

Next 6 Digits are MMMMMM – ICAI’s Membership No. (304576 in this case)

Next 10 Digits are AANNNAANNN –Alpha-numeric generated randomly by the system (AKTSBN1359).

There is no fee for registration and generation of UDIN.

UDIN is totally secure as it can be viewed only by the Member and/ or the Regulators / other Stakeholders who are having the UDIN. Secondly, it does not contain any information of the client.

UDIN is to be generated at the time of signing the Certificate. However, the same can be generated within 15 days of the signing of the same (i.e within 15 days from the date mentioned at Certificates and not beyond that)

No document is required to be uploaded for generating UDIN.

It is mandatory to obtain UDIN for all Certificates* issued where the Financial Information/related contents is certified as True and Fair / True and Correct

Members attention is drawn that AASB (Auditing and Assurance Standard Board) of ICAI  has already issued Guidance Note on Reports or Certificates for Special Purposes (Revised 2016) with illustrative formats, to be followed by the Practicing Chartered Accountants.

A dropdown illustrative list as below is appearing on the Portal from which the Member can select the certificate they are going to issue.

No. UDIN is to be generated for Assignment wise and same UDIN is to be used in all documents signed under that assignment. Say for Example while signing the various certificates while doing Bank Audit, same UDIN can be used for all certificates to be signed for that particular Bank Audit Assignment.

There is no limit on generation of UDIN and there is no restriction on the number of UDIN to be generated.

UDIN shall be mentioned after every Signature and Membership Number of the Member.

There is no need for fresh registration for every financial year.

No, separate UDIN is required for each assignment and is to be used for all documents issued under that assignment.

There is no provision of such uploading. It has to be generated one by one.

UDIN has no connection with Member’s Digital Signature and therefore no changes are required in Digital Signature.

There is no option to generate UDIN in advance. However there is option given to generate UDIN within 15 days of signing of the certificate.

Generated UDIN has no expiry unless revoked.

UDIN generation has been made mandatory as per the Council Decision hence not generating UDIN for mandatory documents will amount to non-adherence of the Council Decision and may attract disciplinary proceedings as per the Second Schedule Part II of The Chartered Accountants Act, 1949.

The UDIN so indicated on certificate can be searched through the search option on UDIN Portal by sharing few details such as Name of the Authority, Mobile Number and Email of the person searching the UDIN. However they are not required to register themselves on the UDIN Portal.

ICAI has made awareness about mandatory applicability of UDIN to all regulators like RBI, SEBI, CBDT, MCA, IBA and they can very well ask for UDIN.

For Statutory Bank Audit, UDIN is not mandatory. However, for all Certificates to be signed while conducting Bank Audit, generation of UDIN is mandatory as UDIN is already mandatory on all Certification w.e.f 1^st Feb.,2019.

UDIN has to be generated per Assignment per Signatory.

In Bank Branch Audit, One Branch is one assignment, hence, one UDIN for all certificates will suffice.

However, care should be taken that a list of all certificates bearing same UDIN should be compiled and handed over to management under a covering letter so that the UDIN generated cannot be misused by affixing on any other certificate which has not been signed by you.

UDIN has to be taken per Assignment per Signatory. Bank Branch Audit per Branch is one assignment and hence one UDIN for all certificates is enough.

However, if different partners are signing different certificates then separate UDIN has to be taken per signatory for the certificates signed by them.

In the 2nd phase of UDIN applicability, ICAI Council has made generation of UDIN mandatory for all GST Audit and All Tax Audit from 1st April, 2019. Hence in Bank Branch Audit, separate UDIN has to be taken for Tax Audit.

Tax Audit is the separate assignment. Hence separate UDINs have to be taken while conducting Bank Branch Audit for each Branch.

Therefore, 2 separate UDINs are to be generated – one for Certificates and other for Tax Audit Report.

However, if certificates are signed by more than one partner then more UDINs on certificates have to be generated.

Yes, UDIN is applicable to both SCAs and SBAs for Certificates and Tax Audit Reports while conducting Bank Audit.

As per UDIN applicability in 2^nd Phase, UDIN is not required to be generated for LFAR and other Bank Audit Reports now.

While generating one UDIN for all the Certificates, some common figures /parameters should be given in 3 mandatory fields and if no common figure is there then name of the Bank and Branch, Advances, Deposits etc must be the one common field which can be correlated with all the certificates.

UDIN will be applicable both for manually as well as digitally signed Reports / uploaded online. In case of digitally signed / online reports, UDIN has to be generated and retained for providing the same on being asked by any third party/ authority.
