Collected
First custody. Who held it, the piece count, the origin dock. If this scan is missing, the freight has not entered the network — a quote is not a collection.
At hub
Sort, ULD build or container stuff. Bay and scan type stay on the number.
Linehaul
Air, ocean or road as their own events. Customs, when it applies, is a sibling state, not a footnote.
Out for delivery
A named run and a window. You can request a redirect before the first attempt if the piece is eligible.
Attempted
A miss. It creates an exception with an owner, not a second tracking number. Use delivery management or the desk.
Delivered
Proof when the service requires it: signature, GPS, photograph. POD documents unlock after this scan for eligible accounts.
