Suffix number plates were introduced in 1963 as a means of providing ever more combinations for the increasing number of vehicles on the roads.
The format uses the letter (or suffix) to identify the year of issue- see below for the relevant dates.
This was the first time in the UK that a number plate could be used to identify the year of a car's registration- something not possible with the series of dateless number plates.
