UK car number plates – a potted history

Number Plates

We’re so used to number plates on our cars we tend to take them for granted other than when we’re looking for a cool personalised number plates. They’ve been a legal requirement for all vehicles since the passing of the Motor Car Act 1903 which came into effect on New Years Day 1904. With an increase in vehicles on the road around that time, accidents and incidents became more common and a system to identify vehicles was needed, and so the license plate was born and has been in existence ever since.

Early number plates had a black background with either white, silver or grey characters. This plate design was phased out in 1973 and you can now only display this type of plate on a vehicle that was manufactured prior to 1973.

The first system of car number plates ran from 1903 until 1932 and consisted of a two letter code representing the local authority and a number from 1 to 9999. As the motor car became increasingly popular the permeations ran out, and a new system was needed. The numbers were reduced from four to 3 and an extra letter code was added. This system ran until 1963 when more combinations were needed yet again and so a suffix letter was added. When the letters ran out in 1982, the system was reversed and a letter was then added before the numbers.

Finally in 2001 another new system was introduced which incorporated a three character suffix and a two digit date identifier.

    It’s like you said, we take number plates for granted and as a totally normal thing these days but thank-fully the number plate system was invented! It would cause havoc without it. Just buying a car or vehicle now days is hard enough without reg plates it would probably be impossible.

    But, thankfully reg plates do exist so when I’m buying a used car i do a reg check using a service like http://www.rapidcarcheck.co.uk – without vehicle registrations this just wouldn’t be possible.
