The pre-requisite for generation of eway bill is that the person who generates eway bill should be a registered person on GST portal and he should register in the eway bill portal. If the transporter is not registered person under GST it is mandatory for him to get enrolled on e-waybill portal (https://ewaybillgst.gov.in) before generation of the e-way bill. The documents such as tax invoice or bill of sale or delivery challan and Transporter’s Id, who is transporting the goods with transporter document number or the vehicle number in which the goods are transported, must be available with the person who is generating the e-way bill.
