E-Way Bill Number Format Change 2027: 14-Digit EWB Proposal

GSTN has proposed longer identification numbers for regular and consolidated E-Way Bills from 1 January 2027. This is a numbering-format update, not a new E-Way Bill filing procedure.

GSTN Advisory No. 687 • 4 November 2026. The new formats are proposed, with Sandbox testing details to follow.

TaxPower GST E-Way Bill number format change 2027: 12 to 14 digits, consolidated E-Way Bill 10 to 11 digits, proposed 1 January 2027

What is changing?

E-Way Bill Number12 digits → 14 digits
Consolidated E-Way Bill Number10 digits → 11 digits

Proposed date: 1 January 2027. The advisory does not say that these longer numbers are already in use in the production system.

1. Why is GSTN changing the number format?

GSTN says the large volume of E-Way Bills generated is expected to exhaust the current numbering capacity. Increasing the length will allow more numbers to be issued. A consolidated E-Way Bill is used when multiple E-Way Bills for consignments are grouped for transportation in one conveyance.

2. Who should take note?

The update is relevant to businesses and transporters using E-Way Bills, as well as GSPs, ERP/software providers and API integrators. Systems that store, search, validate or exchange E-Way Bill numbers may need to accommodate the longer formats.

The advisory is about number length; it does not itself announce a change to the existing value threshold, validity period or tax rates.

3. What should businesses and software users check?

  • Check whether your billing or transport software accepts the proposed longer numbers.
  • Review E-Way Bill fields in imports, exports, reports and searches.
  • Ask your software provider about testing when GSTN releases the Sandbox changes.
  • Keep track of further GSTN technical communication before making final implementation assumptions.

GSTN has said the revised formats will be available in the Sandbox environment for testing and the details will be announced on the E-Way Bill Portal.

4. TaxPower GST software readiness

TaxPower GST has incorporated relevant E-Way Bill system changes in previous software updates. The proposed numbering change will be assessed and incorporated in the applicable TaxPower GST workflows as GSTN makes the technical details and testing facilities available.

Specific release readiness will be confirmed after the relevant implementation and testing. Users need not assume that the new number formats are already operational.

5. Quick FAQs

No. GSTN described the new number lengths as proposed from 1 January 2027. Follow subsequent GSTN confirmation and technical details.

The advisory announces a proposed change in numbering length; it does not describe a new generation procedure. Future technical updates may clarify system changes.
