you will find the 80xxxxxxxx number in the Order Status/Track My Parcel page on the Apple website only when your parcel has shipped from the factory, if it ships from ant distribution centre (ie in stock) it wont get an 80 number.
When the parcel has reached a distribution hub, usually it then gets passed to a different carrier, which one depends on the destination country. For the UK this is usually UPS, for large parts of Europe it woud appear to be TNT. For this final leg of the delivery, your tracking number in the Order Status/Track My Parcel page will change to reflect the new carrier. Expect delivery within the next 2 workign days unless you live a long way from civilisation.
one thing I did note is that some of the processes behind the tracking do take time to update. I dont think this is apecode's fault, but obviosuly some of these are batch processes that only update nightly.
