How is e-Way Bill validity calculated?

e-Way Bill validity is primarily determined by the distance the goods need to travel and the applicable type of cargo. Regular consignments and Over Dimensional Cargo follow different distance-based validity rules.

Type of consignmentDistanceValidity
Regular cargoUp to 200 km1 day
Every additional 200 km or part thereof+1 day
Over Dimensional Cargo (ODC)Up to 20 km1 day
Every additional 20 km or part thereof+1 day
Transport by ship or vesselEvery 200 km or part thereof1 day
Additional allowance for sea transport+2 days

Regular cargo

Validity = Distance ÷ 200, rounded up

650 km ÷ 200 = 3.25 → 4 days

Over Dimensional Cargo

Validity = Distance ÷ 20, rounded up

65 km ÷ 20 = 3.25 → 4 days

Ship or vessel

Validity = (Distance ÷ 200, rounded up) + 2

650 km ÷ 200 = 3.25 → 4 days, + 2 days = 6 days

e-Way Bill validity period by distance

Quickly check the standard validity period for regular goods based on the approximate distance of transportation.

Approximate distanceValidity for regular cargo
Up to 200 km1 day
201 – 400 km2 days
401 – 600 km3 days
601 – 800 km4 days
801 – 1,000 km5 days
1,001 – 1,200 km6 days
1,201 – 1,400 km7 days
2,000 km10 days
Transporting ODC? Over Dimensional Cargo follows a different validity rule of 1 day for every 20 km or part thereof, so the same distance produces a much longer validity.

Regular cargo and ODC follow different validity rules

200 km = 1 day

Regular cargo

Validity increases by one day for every additional 200 km or part thereof.

Example: 450 km → 3 days
20 km = 1 day

Over Dimensional Cargo (ODC)

Validity increases by one day for every additional 20 km or part thereof.

Example: 100 km → 5 days
200 km + 2 days

Ship or vessel

Distance is counted on the 200 km rule, and two extra days are added for sea transport.

Example: 500 km → 5 days

Over Dimensional Cargo refers to cargo carried as a single indivisible unit that exceeds the dimensional limits prescribed under the applicable motor vehicle rules. Where the consignment moves by ship or vessel, the distance is counted on the 200 km rule and two additional days are allowed on top of it, in recognition of the longer handling time involved in sea movement.

What your validity result tells you

The calculator returns four values. Here is what each one means for your consignment.

Validity period

The number of days for which the e-Way Bill remains valid based on the entered distance and cargo type.

Expiry date

The date on which the calculated validity period ends.

Expiry time

Shows when the calculated validity ends, counted as 24 hours per day from the date and time of generation.

Extension window

Shows the permitted period around expiry during which validity may be extended, subject to applicable conditions.

e-Way Bill validity calculation examples

Any part of a distance block counts as a whole day, so the result is always rounded up.

Regular cargo — 350 km

350 ÷ 200 = 1.75, rounded up to the next whole day

2 days
Regular cargo — 750 km

750 ÷ 200 = 3.75, rounded up to the next whole day

4 days
ODC — 250 km

250 ÷ 20 = 12.5, rounded up to the next whole day

13 days

What is an e-Way Bill?

An e-Way Bill is an electronic document generated on the e-Way Bill portal for the movement of goods under GST. It is generally required where the consignment value exceeds ₹50,000, subject to the applicable rules, notifications and State or Union Territory provisions.

The document has two parts. Part A carries the details of the supply — the parties, the document, the goods and the value. Part B carries the transportation details, such as the vehicle number or the transport document number. Both parts have to be completed before the goods begin their journey.

Once generated, an e-Way Bill does not stay valid indefinitely. Its validity is determined by the approximate distance the consignment has to travel and by the type of cargo being carried. Working out that validity, along with the expiry and the extension window, is exactly what this calculator helps you do.

Why is it important to track e-Way Bill validity?

Avoid expired e-Way Bills

Know the expected validity period before the consignment begins its journey.

Plan long-distance movement

Understand how transportation distance affects the number of validity days.

Know when action may be needed

See the expected expiry and extension window in advance.

Frequently asked questions

Validity depends on the approximate distance of transportation and the type of cargo. Regular cargo gets one day for every 200 km or part thereof. Over Dimensional Cargo gets one day for every 20 km or part thereof.

One day, for regular cargo, since 100 km falls within the first 200 km block. For Over Dimensional Cargo the same distance would give five days.

Three days for regular cargo. 500 ÷ 200 is 2.5, and any part of a block counts as a whole day, so the figure is rounded up to three.

Five days for regular cargo, since 1,000 ÷ 200 works out to exactly five with nothing left over. The same distance would give 50 days for ODC, and seven days if the consignment moves by ship.

From the exact date and time the e-Way Bill is generated, that is, when the Part-B transportation details are first entered — the vehicle number for road movement, or the transport document number for rail, air or ship. It does not run from the invoice date.

Each validity day is counted as 24 hours from the time of generation, so a bill generated at 3:00 pm with three days of validity runs out at 3:00 pm three days later. Validity is also commonly treated as expiring at midnight of the final day, and the calculator shows that reading below the result.

Yes, where the goods cannot be moved within the validity period because of exceptional circumstances such as a transit delay, breakdown, accident or natural calamity. The transporter updates Part B and gives a reason.

Yes, within eight hours after the expiry time. With the eight hours available before expiry, that gives a 16-hour window in all. Once it closes, a fresh e-Way Bill has to be generated instead.

The goods should not continue to move. Transporting goods under an expired e-Way Bill can lead to detention of the vehicle and the goods, and to a penalty of up to 200% of the tax due. Extend the validity within the permitted window, or generate a fresh bill.

No. Updating Part B with a new vehicle number keeps the existing bill accurate for the change in conveyance, but it does not by itself add to the validity period.

Yes. Road, rail and air follow the 200 km rule. Transport by ship or vessel follows the same 200 km rule but gets two extra days on top, so a 500 km sea movement works out to five days rather than three.

ODC stands for Over Dimensional Cargo — cargo carried as a single indivisible unit that exceeds the dimensional limits prescribed under the applicable motor vehicle rules. It follows the 20 km validity rule.

Generally the transporter carrying the consignment, or the person who generated the bill. The extension has to be made within the permitted window and with a valid reason recorded.
