Subject: Communication to taxpayers through eOffice – requirement of Document Identification Number (DIN) – reg.
Attention is invited to Board’s Circular No. 122/41/2019- GST dated 05th November2019 and 128/47/2019-GST dated 23rd December 2019 regarding Generation and Quoting ofDocument Identification Number (DIN), initially on specified documents and subsequentlyexpanded to all communications (including e-mails) sent to taxpayers and concerned persons.
2.Attention is also invited to subsequent Board’s Circular No. 249/06/2025-GST dt. 09thJune 2025 clarifying that for communications via GST common portal (in compliance withSection 169 of the CGST Act, 2017) having verifiable Reference Number (RFN), quoting ofDocument Identification Number (DIN) is not required and such communication bearingRFN is to be treated as a valid communication
3. On similar lines, it has been brought to the notice of the Board that communicationsissued through eOffice of CBIC bear an automatically generated unique ‘Issue number’.However, no online utility was available to verify the authenticity of such communicationsthrough Issue number, hence DIN was required to be generated and quoted on suchcommunications. Now an online utility has been developed and made functional(URLhttps://verifydocument.cbic.gov.in), where the taxpayers and other concerned personscan verify online the electronically generated unique “Issue number” borne oncommunications dispatched using public option in eOffice application by CBIC officers.Upon verification, this utility confirms the Issue number, and other details and providesinformation 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).
4. The name of the office issuing the document is captured from the data availablewithin eOffice, while the document type, recipient name, recipient address, recipient email are entered in the metadata by the officers creating the document. Officers responsible forissuing communications via CBIC’s eOffice must mandatorily fill and ensure correctness ofthis information in the metadata while creating the draft before its approval.
5. In light of the above, quoting separate DIN on such communications dispatched usingpublic option in eOffice application, which already bear issue number, will result into twodifferent electronically generated verifiable unique numbers namely Issue No. & DIN on thesame communication, which renders quoting of separate DIN on such communicationunnecessary. It is therefore decided that for communications dispatched using publicoption in CBIC’s eOffice application, the verifiable eOffice ‘Issue number’ shall bedeemed to be the Document Identification Number and such communication shall be treatedas a valid communication.
6.The Document Identification Number generated through DIN utility shall continue tobe mandatorily quoted on all other communications which have either not been dispatchedusing public option in CBIC’s eOffice application or which do not bear the verifiableReference Number (RFN) generated on GST common portal.
7.To the above extent, Circular No. 122/41/2019- GST dated 05th November 2019,Circular No. 128/47/2019-GST dated 23rd December 2019 and Circular No. 249/06/2025-GST dated 09th June 2025 issued by the Board, stands modified
