A tracking system and method uses a multi-threaded controller to automatically and periodically generate tracking objects that are presented to carrier tracking websites. The tracking objects are retrieved from input queues that receive tracking requests from a scheduler. The carrier tracking website updates the status of package delivery which in turn updates the data in the shipping system server with respect to tracking information. This updated information can be used to automatically generate E-mail notification of package delivery as well as for updated purposes. An instant track component allows a user to obtain prioritized tracking information from the associated carrier tracking website.
