When a package arrives at a UPS hub, it is scanned for information such as the package’s weight and size. After the package is scanned, the UPS hub will assign a package number to the package. The package number is then added to a tracking system. The tracking system will show the package’s location at all times.
The tracking system will also show the status of the package, such as when it was delivered and when it will be delivered next. The tracking system will also show the package’s estimated delivery time.
