In my time as an ´animateur´ on a French campsite I used to wind up the Fench by calling the wrong département to the number that dropped. Oh happy days.
I worked with an English guy who had memorised them all, which I found rather sad.
Same system here for registration, any move away from your regional DVLA ( in my case, Frankfurt) would entail re-registering your vehicle(s), joy of joys. At your own expense of course.

I was a bingo caller. Or ´Lotto`as the Francais call it.

Hopefully the new French registration system will be at least as silly as our 05, 55 etc. one is!
