I think the web age and App are not being updated regularly. Neither the web page or the App indicate I have been assigned. Yet, when I called the 877 telephone number (selecting option 4), the Tesla rep told me he had the VIN for my car, and gave the entire number. The last 4 digits are 6087. Delivery is supposed to be between March 6 and March 20, according to the email that was previously sent to me. This is a white performance model.
Congrats--one more step! ;-)
