Pickup
Pickup is the handoff when the carrier takes the car and the bill of lading is signed. Have the vehicle, the keys, and a person ready. A text that says today is not an appointment unless the dispatch sheet names that day.
Pickup is the carrier taking possession. The driver inspects the car, you inspect the driver's paperwork, and someone signs. After that signature the transit clock can start. Before it, the car is still yours.
What to prepare
The car should match the order: operable or not, empty of forbidden items, and with enough fuel for loading. Remove toll tags you still need. Photograph the panels. Have the keys, including spares if you are sending them. A person who can sign must be there, or you need a written plan for a missed meeting. The pickup window may cover several days. Do not treat a morning text as a clock time unless the carrier committed to that hour.
What today does not mean
Today means the truck might come today. It can also mean the dispatcher hopes so. Ask for a time range and a phone number, and keep the first available date honest. RideShipper does not send the driver. The carrier named on the dispatch sheet does.
