The status "In Transit" on the FedEx tracker means that the package is on its way to its final destination. It does not necessarily mean that the package is moving at the time that the status is checked; it may mean that it is in a FedEx facility.
FedEx offers multiple ways to track packages. Each package is given a tracking number that can be registered with FedEx InSight, a web-based tool that offers professional tracking services. FedEx customers also have the option of receiving shipment notifications via email. These services are available for all incoming, outgoing and third party shipments.
