The Goods and Services Tax (GST) authorities have issued a formal disclosure dated November 04, 2026, claiming that it is highly anticipated that the existing e-way bill numbering capacity may soon be completely exhausted, considering the high volume of e-way bill generation.

Correspondingly, the concerned authorities are planning to propose certain amendments to the existing numbering formats, effective from January 01, 2027. The following are the proposed changes:

Document Type	Existing Format	Proposed Format
E-Way Bill Number	12 digits	14 digits
Consolidated E-Way Bill Number	10 digits	11 digits

Consequently, all the concerned stakeholders, including taxpayers, GSPs, ERP/software providers and API integrators, are recommended to make changes in their applications, APIs, database schemas and validation rules accordingly to fit the revised numbering formats.

According to the disclosure, soon the proposed amendments will be released for testing purposes in the Sandbox environment. Upon their successful clearance of the test, they will be officially implemented. Relevant details related to the testing will be updated on the E-Way Bill Portal.

The GST authorities have urged all the stakeholders to make sure their system is all set/ready well before January 01, 2027, to ensure a smooth transition without any restrictions and to avoid any disruption to E-Way Bill-related operations.
