I used this method (Mac, similar principle for Windows) - in Google Chrome on PC/Laptop right click on your account page, select 'view page source' & then search with cmd-f (or whatever key presses your computer requires to search) & input VIN in the search bar (it gives every occurrence of these 3 letters but if a VIN is assigned it will show up on at least one of these as you scroll through).
