in transit usps meaning refers to the status of a package that has been shipped by USPS but has not yet arrived at the recipient’s address. When a package is marked as “In Transit,” it means that the item is still moving through the USPS network toward its destination. This status can be seen during various stages of the delivery process, such as when a package is being processed at sorting facilities, transferred between locations, or moving through customs for international deliveries. The “In Transit” status typically lasts until the package reaches its final destination or is out for delivery.
