An e-way bill is an electronic document that is mandatory to move commercial goods exceeding ₹50,000 in value, within and outside state borders. An e-way bill is only valid for a certain time depending on the type of cargo being transported and the distance. One of the primary functions of the e-way bill is to facilitate the computation of the applicable GST that is due to the transporter after the goods in question have been delivered. Similarly, it also helps the issuing authorities to keep a track of all the taxable goods that are being moved within and across state borders.

Determinants of Eway Bill Validity

The eway bill’s validity depends upon the distance travelled. Typically, the journey starts from the supplier’s location. Then, the driver has to make it to the next stop at the state border where an e-way bill-generating toll booth is set up. The destination, on the other hand, is the recipient’s location. However, it must be noted that the distance to be travelled is an approximation that is ascertained through the MAP feature on the e-way bill system accessible by the toll booth officials. They use the feature to compute the distance between the dispatch and delivery locations.


Previously, a maximum distance of 3,000-km could be entered in the distance section when an eway bill generation was done online. Such restrictions could theoretically make the transportation of goods from one end of the country to another a next-to-impossible task. However, if the goods can be transported within the stated e-way bill validity period even though the total distance travelled exceeds the 3,000-km limit, there should not be an issue whatsoever.


As a rule of thumb, a single day is added to the total e-way bill validity period after the vehicle has travelled 200-km, while an additional day is added every time the vehicle covers 200-km. If you feel confused by the explanation of how the e-way bill validity is extended, let us help you with an example.

  • If the approximate distance to be travelled is 270 km, the validity period of the e-way bill issued to the driver is 1+1 days. In case Over-Dimensional Cargo (ODC) is being transported, the e-way bill validity is altered by adding a day for every 20 km that the cargo travels.

  • The distance between the two destinations is needed to compute the e-way bill’s validity. After the approximate distance is determined and entered, the details of this field will remain the same as updating it is not possible currently.

However, the computation of the distance travelled by an e-way bill has become simpler. These days, all that a toll booth official must do is enter the pin codes of the location where the journey began and that of the destination. As per the pin codes, the e-way bill devices will be able to measure and show the near-approximate distance that a motor vehicle can travel between the supplier and recipient. The latest amendment to the portal is a facility that allows drivers to enter the actual distance travelled while moving the items.


However, the facility does not allow the driver to change the total distance travelled by a sizable margin. As a carrier who is responsible for the safe and smooth transportation of goods, it will be limited to a 10% increase over the distance that has already been calculated.


For example, if the e-way bill system suggests that the distance between points A and B is 900 km, the user can enter a maximum distance of up to 990 km (900 km + 10% of 900 km).

Extension of Validity Period of E-Way Bill

The validity of an eway bill can be extended if the consignment cannot be transported within the due date. However, the validity of the waybill can only be extended by the supplier or the assigned transporter carrying the goods at the time of expiry.

1. Reasons for Validity Extension

The validity of the eway bill can be extended in the case of change in the transport vehicle, breakdown of the vehicle, or any other such issue.

2. Time Limit for Waybill Extension

The e-way bill can be extended 8 hours prior or 8 hours after the time of expiry of the validity period.

Steps to Extend Validity of E-way Bill

Follow these steps to extend the validity of the e-way bill:

  • Step 1: Login to the official eway bill portal, i.e. E-WayBill System ( Enter the requested details like username, password, and captcha before clicking on ‘Login’.
  • Step 2: Click on the ‘Extend Validity’ option listed under ‘E-waybill’ on the left-hand side of the dashboard.
  • Step 3: Now, enter the eway bill number for which the validity has to be extended.
  • Step 4: Select ‘Yes’ to extend the validity.
  • Step 5: At this stage, you must enter the reasons for the extension. Also, re-enter the details of the vehicle. Make relevant selections from the drop-down list and enter the mandatory remarks.

The system will generate additional validity depending upon the distance travelled.

Points to Remember For Eway Bill Validity

There are certain conditions that you must keep in mind with regards to the eway bill validity. Here is a list:

  • Eway bill validity for the first day will end by midnight of the following day.

  • Eway bill validity will commence once the vehicle number is updated for the first time in the document by the supplier/recipient. This can also be done by the transporter later on, depending upon the distance travelled.
