Subject: Communication to taxpayers through eOffice - requirement of document
Identification Number (DIN) - reg.
Attention is invited to Board's Circular No. 37/2019 dated 05
th
November, 2019 and
43/2019-Customs dated 23
rd
December, 2019, regarding Generation and Quoting of
Document Identification Number (DIN), initially on specified documents and subsequently
expanded to all communications (including e-mails) sent to taxpayers and concerned persons.
2. It has been brought to the notice of the Board that communications issued through
eOffice of CBIC bear an automatically generated unique ‘Issue number’. However, no online
utility was available to verify the authenticity of such communications through Issue number,
hence DIN was required to be generated and quoted on such communications. Now an online
utility has been developed and made functional (URL https://verifydocument.cbic.gov.in),
where the taxpayers and other concerned persons can verify online the electronically
generated unique “Issue number” borne on communications dispatched using public option in
eOffice application by CBIC officers. Upon verification, this utility confirms the Issue
number, and other details and provides information to authenticate the document, like, -
i. File number,
ii. Date of issuing the document,
iii. Type of communication,
iv. Name of Office issuing the document,
v. Recipient name (masked),
vi. Recipient address (masked),
vii. Recipient email (masked).
3. The name of the office issuing the document is captured from the data available
within eOffice, while the document type, recipient name, recipient address, recipient email
are entered in the metadata by the officers creating the document. Officers responsible for
issuing communications via CBIC's eOffice must mandatorily fill and ensure correctness of
this information in the metadata while creating the draft before its approval.
4. In light of the above, quoting separate DIN on such communications dispatched using
public option in eOffice application, which already bear issue number, will result into two
394/39(14)/2018-Commr.(Inv.-Cus.) I/126784/2025

different electronically generated verifiable unique numbers namely Issue No. & DIN on the
same communication, which renders quoting of separate DIN on such communication
unnecessary. It is therefore decided that for communications dispatched using public
option in CBIC’s eOffice application, the verifiable eOffice ‘Issue number’ shall be deemed
to be the Document Identification Number and such communication shall be treated as a valid
communication.
5. The Document Identification Number generated through DIN utility shall continue to
be mandatorily quoted on all other communications which have not been dispatched using
public option in CBIC’s eOffice application.
6. To the above extent, Circular No. 37/2019 dated 05
th
November 2019 and 43/2019-
Customs dated 23

December 2019 issued by the Board, stands modified
