meaning of in transit refers to the status of a shipment as it moves between locations in the supply chain, such as from the sender’s facility to the recipient’s destination. When a package is “in transit,” it means it is on its way but has not yet arrived. This term is commonly used by shipping companies like UPS, DHL, and USPS to describe packages that are actively being transported, whether by air, sea, or land. The in-transit phase may last several days, depending on the destination and shipping method. Updates on a package’s progress are typically provided through tracking numbers, giving customers an idea of the delivery timeline.
