The plate is matched with a VIN using DMV records, which we then decode, to get the Make, Model, etc as you described.
Interesting that you resort to downvoting basic facts...
Also, is it "I" or "we"? You've said it's just you and a project you made, suddenly when someone points out a mistake it's "we"? Make your mind up...
We "match" the plate to a VIN, and then we DECODE the VIN to get all of the data we show on the page. Yes, we decode the VIN, not just "match" it
