Extend Validity means adding more time to an existing e-way bill when the goods cannot be delivered within the original time limit.
There are situations when goods might not reach their destination on time, such as:
Vehicle breakdown
Natural calamity
Road closures or traffic jams
Delay in loading/unloading
Change in route
Others
In such cases, the transporter or the person who created the e-way bill can extend the validity of the e-way bill. The extend validity request must be made either 8 hours before or 8 hours after the e-way bill expires.
