E-Way Bill Extension & Update FAQ
What buyers ask.
How long can validity be extended?
Validity is extended per the distance covered, at the rate of one day per 200 km (16 hours per 200 km). Extension is allowed within 8 hours before or after the original validity expiry.
Vehicle break-down. Can we update the EWB?
Yes. Vehicle change with reason (break-down, transhipment) is captured. The new vehicle replaces the original on the EWB. Audit log preserves the change.
