When a package’s delivery status from USPS reads “Origin Post is Preparing Shipment,” it is now in the last stages of preparation before being sent. This is a typical international shipping status.
Many packages are placed in a single shipping container by international shipping companies before being sent overseas. The status “Origin Post is Preparing Shipment” most often occurs for this reason. This is the final status the parcel will have before entering the local mail system in the country of destination. How long a package remains in this status is heavily dependent on the volume of parcels travelling from the country of origin to the country of destination.
