This is an extremely rare plate, with almost no information about it. This van was originally registered as a ''special vehicle'', which uses the same type of plate number system that trailers and motorcycles use.
But this van was re-registered as a normal van at some point, which gives it green plates. But surprisingly enough it was not given new numbers, but retained the original trailer-style 4 digit letters.
It seems like there are only a handful of green plates with only four numbers in Norway, as officially they should probably not exist.
