Personalised Number Plate Information

The first series of number plates were issued in 1903 and ran until 1932, using the series A 1 to YY 9999. The letter or pair of letters indicated the local authority in whose area the vehicle was registered, for example A - London, B - Lancashire, C - West Riding of Yorkshire. In England and Wales the letter codes were initially allocated in order of population size (by the 1901 census) whilst Scotland and Ireland had their own sequences incorporating the letters S" and "I" respectively, which were allocated alphabetically: IA = Antrim, IB = Armagh, etc. When a licensing authority reached 9999, it was allocated another two letter mark, but there was no pattern to these subsequent allocations as they were allocated on a first come first served basis. There are three interesting anomalies where a zero has been issued - The Lord Provost of Edinburgh has S 0 and his Glasgow counterpart has G 0 while the official car of the Lord Provost of Aberdeen has RG 0. In addition the Lord Mayor

In 1963, numbers were running out once again, and an attempt was made to create a national scheme to alleviate the problem. The three letter, up to three number system was kept, but a letter suffix was added, which changed every year. In this scheme, numbers were drawn from the range AAA 1A to YYY 999A for the first year, then AAA 1B to YYY 999B for the second year, and so on. Some areas did not adopt the year letter for the first two years, sticking to their own schemes, but in 1965 adding the year letter was made compulsory. As well as yielding many more available numbers, it was a handy way for vehicle buyers to know the age of the vehicle immediately. At first the year letter changed on 1 January every year, but car retailers started to notice that buyers would tend to wait until the New Year for the new letter to be issued, so that they could get a newer" car. This led to major peaks and troughs in sales over the year, and to help flatten this out somewhat the industry lobbied

By 1982, the year suffixes had reached Y and so from 1983 onwards the sequence was reversed again, so that the year letter - starting again at A" - preceded the numbers then the letters of the registration. The available range was then A21 AAA to Y999 YYY, the numbers 1-20 being held back for the government's proposed, and later implemented, DVLA select registration sales scheme. Towards the mid-1990s there was some discussion about introducing a unified scheme for Europe, which would also incorporate the country code of origin of the vehicle, but after much debate such a scheme was not adopted due to lack of countries willing to participate. The changes in 1983 also brought the letter Q into use - although on a very small and limited scale. It was used on vehicles of indeterminate age, such as those assembled from kits, substantial rebuilds, or imported vehicles where the documentation is insufficient to determine the age. There was a marked increase in the use of Q registrations
