New CBIC Utility to Verify DIN of eOffice Communications with Issue Number

Circular No. 252/09/2025 – GST | Dated 23rd September 2025

The Central Board of Indirect Taxes and Customs (CBIC) has issued Circular No. 252/09/2025-GST to streamline the process of validating communications issued through CBIC’s eOffice platform. This update reduces duplication and simplifies verification for taxpayers, businesses, and stakeholders.

🔑 Key Background

• Earlier, CBIC mandated quoting of Document Identification Number (DIN) on all communications (Circulars 122/41/2019 & 128/47/2019).
• Later, Circular No. 249/06/2025 clarified that where communications on the GST common portal carried a verifiable Reference Number (RFN), a separate DIN was not required.
• Until now, communications issued through CBIC’s eOffice system also required a DIN because there was no mechanism to verify the automatically generated “Issue Number.”

🆕 What Has Changed?

With the release of this circular, CBIC has announced:

1. Online Verification Utility Launched
   • A new tool at https://verifydocument.cbic.gov.in allows taxpayers to verify Issue Numbers generated in eOffice.
   • Verification provides details like:
     • File number
     • Date of issue
     • Type of communication
     • Issuing office name
     • Recipient details (masked for privacy)
2. Issue Number = DIN (for eOffice communications)
   • For communications dispatched using public option in eOffice, the automatically generated Issue Numberwill now be deemed as the Document Identification Number (DIN).
   • A separate DIN need not be generated in such cases.
3. DIN Still Mandatory in Other Cases
   • DIN must continue to be quoted where:
     • Communication is not dispatched via eOffice’s public option.
     • Communication does not carry an RFN from GST common portal.

📝 Compliance Instructions for CBIC Officers

• While drafting documents in eOffice, officers must correctly fill metadata (document type, recipient name, address, and email).
• The issuing office name will auto-populate from the system.
• Accuracy in metadata is essential, as these details will be used for online verification.

📌 Modifications to Previous Circulars

This circular modifies earlier directions to the extent noted:

• Circular No. 122/41/2019-GST (05 Nov 2019)
• Circular No. 128/47/2019-GST (23 Dec 2019)
• Circular No. 249/06/2025-GST (09 June 2025)

Now, eOffice Issue Numbers are considered valid DINs, removing redundancy.

📊 Practical Example for Businesses

Example 1: Communication via GST Portal

• A taxpayer receives an order via GST common portal with RFN.
• ✅ RFN is sufficient. No DIN is required.

Example 2: Communication via eOffice (Public Option)

• A taxpayer gets a notice from CBIC eOffice with Issue Number.
• ✅ The taxpayer can verify this at CBIC’s new utility. DIN is not separately needed.

Example 3: Email/Letter Not via Portal or eOffice

• A taxpayer receives an email/letter without RFN or eOffice Issue Number.
• ❌ A valid DIN must be quoted on such communication.

📢 Impact on Taxpayers & Businesses

• Simplified verification of CBIC communications.
• Reduced duplication of DIN and Issue Numbers.
• Stronger safeguards against fraudulent or unauthenticated notices.

✅ Conclusion

Circular No. 252/09/2025 is a step towards ease of doing business by eliminating duplicate identification requirements and offering a simple online utility for verification. From now onwards, taxpayers can rely on the eOffice Issue Numberitself as a valid DIN for authenticity of communications.
