Where do the letters come from?
The letters in registration plates are seemingly random to most, however there is sensical reasoning behind each section of a plate.
The first two letters of a registration plate are referred to by DVLA as ‘memory tags’. These memory tags identify the region in which the car was registered and even more specifically, which postal area within the region.
As addressed earlier, the numbers (or age-identifier) represent the year the car was registered.
The final three letters on any UK registration plate are generated randomly. The only letters that are never used in registration plates are I and Q, whilst Z only makes rare appearances.
