e-way Bill expired

what is process of Expired e-way bill  will be re-valied

under circumstance of ‘exceptional nature and trans-shipment’, the transporter may extend the validity period after updating reason for the extension and the details in PART-B of FORM GST EWB-01.

This option is available for extension of e-way bill before 4 hours and after 4 hours of expiry of the validity. Here, transporter will enter the e-way bill number and enter the reason for the requesting the extension, from place (current place), approximate distance to travel and Part-B details. It may be noted that he cannot change the details of Part-A. He will get the extended validity based on the remaining distance to travel.
