Seems like a bunch of comedians answering you here. The numbers are inside the cabin trim panel just aft of the right rear door. It's not that hard to get to, but you have to be patient figuring out the panel clips on the B-pillar.
Pull off all the weather stripping around the door opening, and that allows you to peek inside the panel. If you are good with an inspection mirror and a good flashlight, you can see it without removing the panel. Good luck.
