If you want your VIN or to know where your car is, maybe I can help. I was one of the first to get a Shanghai car, (Model Y) last summer. Your SA has access to your info on their laptop through the "Tesla OS Transport Management System " Your ViN is there. They can tell you if your car is on the ship. Also the exact date and time it left the factory to the very second and the delivery ETA. They can even tell you the battery SOC. Mine was 50.6% while at the factory yard. The mileage too and that's important. If it's at about 3.5 kms, then your car is at the factory yard. If it's at about 11 kms, then your car was driven from the plant to the port and may be there or on the ship.
To get all this info, don't waste everyone's time with emails or phone calls. Vist your SA in person and have your order number ready. Visit when they are NOT BUSY. Maybe 20 minutes after they open or such. Find a SA that is not busy with customers. Younger ones seem especially enthusiastic and helpful. Also, don't fret if your car is not on the first ship. It could be on either the first or second ship for no apparent reason. The second ship will come real soon after the first. I know many of you are bursting with excitement as you should be. Hopefully this will help. Good luck.
