It may be used for creating a new shipment, updating or replacing a shipment, or canceling a shipment. Shippers may include manufacturers, distribution centers, wholesalers, or any other organization that handles and ships goods.
A 204 transaction typically provides detailed pick-up and delivery information for a load, usually for a single pick-up location. This may include all or some of the following:
Carrier identification information
Equipment requirements, such as length of truck required
Ship-to location information
Contact information for shipment recipient
Information on consignees, if relevant
Description of goods, including weight and other units of measure
The 204 transaction set is only for full-truckload shipments; thus, it is not to be used for providing motor carriers with less-than-truckload bill of lading information.
