What is pre shipment usps?

Pre-shipment USPS refers to the stage in the shipping process before the package has been physically accepted and scanned by the United States Postal Service (USPS). During this phase, the sender has created a shipping label, but the package has not yet been handed over to USPS for delivery.

At this stage, the sender might receive a tracking number, but the status will show as "Pre-Shipment" until the package is officially in the possession of USPS. It is common for the pre-shipment status to last anywhere from a few hours to a few days, depending on the volume of packages being processed by USPS.

If your package is stuck in pre-shipment for an extended period of time, it could indicate that the sender has not yet dropped off the package or that there is a delay in the shipment process. In most cases, the package will eventually be scanned by USPS and continue on its journey to its destination.

Overall, pre-shipment USPS is simply the stage in the shipping process before USPS takes possession of the package and begins tracking its progress towards delivery.
