From my experience I assumed the "Tracking Number" was generated and sent based on a scheduled pickup. It took a few days before the shipper showed it in their system.
Hi,
FedEx website can take up to 2 business days before the tracking number gets activated. The tracking number is attributed and emailed only once the order has been physically picked up by FedEx.
I would also note, at least here on the east coast, the initial delivery date in the system was incorrect. It showed up several days earlier. Again, my assumption was that they add a little wiggle room for customs but that's just a guess.
The delivery date is generated by FedEx and usually it is delivered a few days ahead of their expected delivery date.
