The reform aims to reduce compliance hassles, streamline verification and boost administrative efficiency. By officially recognising the e-office Issue Number alongside DIN and RFN, CBIC is reinforcing its commitment to digital transformation and modernising taxpayer interactions.
From DIN/RFN to issue number: An evolution in communication
Introduced in 2019, the DIN system was designed to ensure that every official communication, such as notices, summons, inspection letters, or adjudication orders, could be uniquely identified and verified. It aimed to curb discretion, prevent misuse of authority and enhance accountability across the GST and Customs ecosystem.
As the GST administration became increasingly digitised, most statutory documents began to be issued directly through the GST common portal. These documents automatically included an RFN, which fulfilled the same purpose as DIN: ensuring uniqueness, traceability, and verifiability.
With further adoption of digital tools like the CBIC e-office application, documents generated through this platform began carrying unique Issue Numbers. The new circulars now formally recognise these Issue Numbers as valid substitutes for DIN, provided they can be verified through the e-office portal.
Verification process
Taxpayers and stakeholders can verify the Issue Number online using the public verification utility in the CBIC e-office application. Upon verification, the portal confirms the Issue Number and displays key details such as:
- File number
- Date of issuance
- Type of communication
- Issuing office
- Masked recipient name, address, and email
For communications that do not carry an RFN or Issue Number, such as physical letters or emails, the DIN requirement remains mandatory. Officers must include a DIN on such documents, which can be verified through CBIC’s dedicated DIN verification utility.
Enhancing transparency and efficiency
The reform is part of CBIC’s broader initiative to simplify taxpayer interactions and enhance transparency. By reducing procedural overlap and leveraging digital platforms, the Board aims to build greater trust in the tax administration.
Internally, the move improves operational efficiency. Officers no longer need to generate a separate DIN for documents already issued via the e-office system, reducing duplication and aligning with the government’s goal of minimising manual intervention.
CBIC continues to prioritise transparency, technology, and taxpayer convenience in its reforms. The latest circular complements earlier initiatives such as faceless adjudication, digital customs clearance, and enhanced grievance redressal mechanisms, marking another step forward in the modernisation of India’s indirect tax regime.
