GST
The CBIC had earlier made it mandatory to mention a Document Identification Number (DIN) on all communications issued to taxpayers, to ensure transparency and accountability. However, it has now been clarified that any communication issued through the GST common portal – such as notices or orders – already carries a unique Reference Number (RFN) which can be verified online. Since these documents are served through the portal as per legal provisions under the CGST Act, and already have a verifiable RFN, there is no need to mention DIN on them. Therefore, DIN is not required for any GST communication generated and served through the portal. To this extent, the earlier circulars requiring mandatory DIN on all communications have been modified.
