The phones are still on preparing for shipment at the Apple system, but you can surely get simple status updates with UPS and track them by reference number.
See my screenshot attached.
Go to the ups website, select „track by reference number“, and type your order number „Wxxxxxxxxx“ without the last two digits in that field.
Then expand the begin date to your order date so that the timespan should include your delivery and the simple tracking should find it if it’s already shipped from China.
When all the devices arrive at their target airport, and run through the initial scan, every customer gets the real tracking number from Apple.
In the last years some iPhone preorders shipped from UPS station in Czech, Netherlands or two years ago from Cologne with DHL to southern Germany in my case.
But no matter what target station it will be, all of them need the initial flight coming from China.
