The National Informatics Centre (NIC) has announced an enhancement of interoperable services between the E-Way Bill 1 and E-Way Bill 2 portals. Following the initial launch of these services in September 2024, which only allowed for updating Part B and getting E-Way Bill details, the August 2025 update introduces several key new features. Users can now perform additional "criss-cross" operations, meaning they can manage E-Way Bills generated on one portal using the other. The new functionalities include the first-time updating of Part B for Part A slips, allowing users to complete a bill's details regardless of the portal it was initiated on. Additionally, the update enables the extension of an E-Way Bill's validity and the updating of transporter details from either portal. These enhancements are designed for emergency or fallback use, ensuring business continuity in case one portal is temporarily unavailable. Users are advised to wait for at least two minutes for data to sync between the portals when performing these cross-portal operations to avoid delays.

Enhancement of Interoperable Services between E-Way Bill 1 and E-Way Bill 2 Portals
(Dated: 05.08.2024)

As you are aware, NIC implemented the Interoperable services for the E-Way Bill 1 and E-Way Bill 2 portals in September 2024.

In the initial release, only the following criss-cross operations were enabled:

• Updating of Part B
• Get EWB

That is, E-Way Bills generated on E-Way Bill 1 (with at least one Part B entry made on E-Way Bill 1) were allowed to update Part B from E-Way Bill 2. Similarly, E-Way Bills generated on E-Way Bill 2 were accessible from the same portal for such operations.

Enhanced Criss-Cross Operations – August 2025

We are pleased to inform you that the following additional criss-cross operations have now been enabled:

1. Updating of Part B for Part A Slips (First-Time Update):

It is now possible to update Part B for Part A slips across portals, even for the first time.

Examples:

• For a Part A slip generated at E-Way Bill 1, Part B can be updated at E-Way Bill 2.
• For a Part A slip generated at E-Way Bill 2, Part B can be updated at E-Way Bill 1.

2. Extension of E-Way Bill:

You can now extend the validity of an E-Way Bill generated at one portal using the other portal.

• E-Way Bill generated at E-Way Bill 1 can be extended at E-Way Bill 2.
• E-Way Bill generated at E-Way Bill 2 can be extended at E-Way Bill 1.

3. Updating of Transporter:

It is now possible to update transporter details across portals.

• • Transporter can be updated for E-Way Bills generated at E-Way Bill 1 from E-Way Bill 2, and vice versa.

In the earlier release the following criss-cross operations were enabled

New release the following Enhanced Criss-Cross Operations.

Note:

1. Interoperable Services between the E-Way Bill 1 and E-Way Bill 2 portals are intended primarily for emergency or fall back use only.

In case the E-Way Bill 1 portal becomes temporarily unavailable, users may switch to the E-Way Bill 2 portal to continue generating and managing E-Way Bills without disrupting their business operations.

2. When using Interoperable Services between the two portals, updates may take some time to reflect in functions such as Print/Get Details.

Therefore, during cross-portal operations, please wait for at least 2 minutes for the data to sync between the portals before performing any subsequent actions.
