The CBIC has issued an Circular No. 252/09/2025 -GST dated 23.09.2025, streamlining the requirement of quoting Document Identification Number (DIN) on official communications issued to taxpayers.

The present circular addresses the case of eOffice communications. All communications issued through CBIC’s eOffice application carry an automatically generated Issue Number, but previously, since no online verification mechanism existed, a separate DIN was required, leading to duplication. A new verification utility https://verifydocument.cbic.gov.in has now been introduced, which enables taxpayers to verify the Issue Number and confirm document authenticity. The system provides details such as file number, issue date, communication type, issuing office, and masked recipient details.

Accordingly, it has been clarified that:

• The eOffice Issue Number will be treated as DIN for all communications dispatched through the public option in the eOffice system.
• A separate DIN is not required for such communications.
• DIN will continue to be mandatory for all other communications not issued via eOffice public option or not carrying RFN from the GST common portal.
• Officers must ensure accuracy of metadata (recipient details, document type, etc.) while creating communications in eOffice.

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.
