GST Circular No 252-09-2025- DIN not Mandatory
As per GST Circular No 252-09-2025 DIN is not mandatory for eOffice communications with issue number.Earlier, CBIC made it mandatory to generate and quote a Document Identification Number (DIN) on all official communications sent to taxpayers (Circulars 122/2019 & 128/2019).Later, Circular 249/06/2025 clarified that if a communication is issued through the GST common portal with a Reference Number (RFN), then DIN is not needed, since RFN itself is a valid, verifiable number.
CBIC also sends communications through its eOffice system. These communications automatically have a unique “Issue Number”, but earlier there was no online utility to verify it, so DIN had to be separately generated. Now, CBIC has launched an online verification utility: 👉 https://verifydocument.cbic.gov.in Using this, taxpayers can verify the authenticity of the communication by entering the Issue Number.
The utility will show details like:
- File number
- Date of issue
- Type of communication
- Issuing office name
- Recipient details (masked for privacy: name, address, email)
While creating documents in eOffice, officers must correctly fill in metadata (like document type, recipient details, etc.) because these details appear in the verification utility.
If a communication is sent through eOffice using the public option and it bears a verifiable Issue Number, then:
- That Issue Number itself will be treated as DIN.
- No need to generate a separate DIN.
If communication is sent outside eOffice, or via eOffice but without Issue Number verification, or through GST portal but without RFN, then DIN must still be quoted.
To this extent, the earlier Circulars (122/2019, 128/2019, 249/2025) stand modified.
