Is there some sort of geographic clustering going on with UK car number plates? Inquiring minds want to know.

The only source of clustering on the number part I can think of would have been due to a dealership getting a large set of registrations at once (as, apart from the low numbered plates that were sold off separately, numbers were allocated within each area sequentially).

Since 2001 the number indicates the six month period the car was registered in, I don't know the allocation system for the three letter id part now used to distinguish between cars from the same six month period and area, and I don't know how many offensive letter combinations are excluded, but spotting roughly 14000 plates is probably a challenge too big even for [livejournal.com profile] bugshaw

Humph. I was going to write a detailed explanation of the subtleties of information storage in British car number plates and how they ocnvey information about date and place of vehicle registration, but I see Wikipedia has got there already.

Sark bans cars on its roads, so no number plates exist.

I love Wikipedia sometimes.

Cool. California doesn't seem to have any such rationality behind our plates; it's just sequential and any clustering is at the whim of the CA Department of Motor Vehicles (respect their authority, capricious though it may be!).
