How to Update Vehicle Number in E-Way Bill
Last Updated: August 2026
Loads often change trucks after the e-way bill is generated. Updating the vehicle number (Part B) keeps the movement document aligned with the vehicle that actually rolls—critical for transporters and market-hire fleets.
Summary
Updating vehicle details on an e-way bill keeps Part B current when the truck changes. Do it before the new vehicle moves the goods.
Why vehicle updates happen
- Shipper generated EWB before transporter assigned the final truck
- Breakdown and transshipment mid-route
- Market vehicle replaced after booking
Practical steps (portal mindset)
- Open the e-way bill on the official portal (or approved integrated system)
- Use the vehicle update / Part B update action for that EWB
- Enter the new vehicle number carefully (format matters)
- Confirm and save the updated bill
- Share the updated EWB with the driver and branch
Exact button labels follow the current portal UI—use ewaybillgst.gov.in as source of truth.
Internal control tip
Never let a truck leave with a different number than the EWB. Put “vehicle = EWB Part B” on your gate checklist.
