Once the Fedex package has been picked up from our company changing the delivery is difficult given Fedex's system. It the package is going to a U.S. address and was shipped via Fedex Express, it is possible to make the request. Fedex charges $11 to make the change (which our company will not cover), and in our experience, even with the fee, Fedex cannot guarantee that they will be able to successfully update the address before the initial delivery request is made. This is due to the requests being routed initially through their call center, and then sent to the various offices and finally to the Fedex driver. Typically it takes at least 24 hours for the station and driver to receive the notice.
Because of the difficulty involved in chaning the address once the package is shipped, it is a very good idea to provide us with the best delivery address when the order is placed. A request can also be made to have the package held for pickup at the Fedex station if you will not be available once the package has been delivered. This can often be done directly on the Fedex website with the tracking number or by calling 1-800-GO-FEDEX
In the case of Fedex Ground, Fedex International and USPS shipments, changing the delivery address is not possible.
