After reviewing, it appears that you entered only “Part A” details when creating the E-waybill. However, your transporter has filled out the “Part B” details later, meaning only the transporter can extend the E-waybill. We kindly request you to check with your transporter about extending the E-waybill.
The transporter will enter the e-way bill number and enter the reason for requesting the extension, from place (current place), approximate distance to travel and Part-B details. Please note that the transporter cannot change the details of Part-A. They will get the extended validity based on the remaining distance to travel.
