How e-way bill validity works
An e-way bill is mandatory when the consignment value exceeds ₹50,000. Its validity depends only on the distance the goods travel and the type of cargo. For regular cargo you get one day for every 200 km (or part thereof); for Over-Dimensional Cargo (ODC) or multimodal shipments involving a ship, you get one day for every 20 km (or part thereof).
Validity slabs — days by distance
Validity is calculated by dividing the distance by the per-day limit and rounding up to the next whole day (any part of a slab counts as a full day). One day means the period ending at midnight of the day following the relevant slab.
| Up to 200 km | 1 day |
| 201 – 400 km | 2 days |
| 401 – 600 km | 3 days |
| 601 – 800 km | 4 days |
| Each additional 200 km (or part) | +1 day |
| Up to 20 km | 1 day |
| 21 – 40 km | 2 days |
| 41 – 60 km | 3 days |
| 61 – 80 km | 4 days |
| Each additional 20 km (or part) | +1 day |
Worked examples
The rule is simple: days = distance ÷ per-day limit, rounded up. Here are the numbers this calculator produces:
Key terms explained
Part-A and Part-B
Part-A captures the invoice details (GSTIN, value, HSN, place of delivery). Part-B carries the transport / vehicle number. An e-way bill is valid only when both parts are complete; validity is counted from the time Part-B is first entered.
Over-Dimensional Cargo (ODC)
Cargo that exceeds the dimensional limits prescribed under the Motor Vehicles Rules. ODC moves slowly, so validity is far more generous — one day per 20 km instead of 200 km. The same slower rate applies to multimodal transport that includes a ship leg.
Midnight rule
"One day" does not mean 24 hours. The first day runs till midnight of the day following generation; validity ends at midnight of the day the last slab closes. A bill generated at 2 PM is valid the same way as one generated at 10 AM.
Extending validity
If goods cannot reach in time, the transporter can extend the e-way bill within 8 hours before or 8 hours after expiry. One e-way bill covers one consignment; each additional consignment needs its own bill.
How is e-way bill validity calculated?
One day for every 200 km or part thereof for regular cargo, and one day for every 20 km or part thereof for over-dimensional cargo and multimodal shipments involving a ship leg. A "day" ends at midnight of the day following the generation time.
When does validity start?
From the time Part B — the vehicle details — is first entered, not from when Part A was filled. Entering Part A alone does not start the clock.
Can e-way bill validity be extended?
Yes, within eight hours before or after expiry, by giving the reason and the remaining distance. It cannot be extended once that window has closed.
What if goods are stuck in transit and the bill expires?
Move under a valid extended bill wherever possible. If the bill has lapsed, the consignment is liable to detention under section 129, and the usual remedy is to explain the exceptional circumstance to the proper officer.
Does the vehicle number have to be updated on transhipment?
Yes. Whenever goods change vehicles, Part B must be updated with the new vehicle number before the movement continues. The validity period does not restart on updating.
