CBIC has released Circular No. 249/06/2025-GST, removing the mandatory use of DIN for communications issued via the GST portal. However, DIN remains compulsory for eOffice-based documents, as clarified in Circulars No. 23/2025 - Customs and 252/09/2025 - GST. This blog explains the changes and what taxpayers need to know.

The CBIC has clarified that GST notices from the official portal are now valid with a Reference Number (RFN), even without a separate Document Identification Number (DIN). The RFN serves as a unique identifier, making the DIN redundant for these digital communications. This move aims to reduce confusion, simplify verification, and emphasize digital communication. Taxpayers can use the RFN on the GST website to authenticate notices. Caution is advised for notices received without a DIN via other channels.
