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

The three-letter scheme preserved the area letter codes as the second pair of letters in the set of three, and the single letter area codes were deleted (since prefixing a single letter code would create a duplicate of a two-letter code). In some areas, the available numbers with this scheme started to run out in the 1950s, and in those areas, a reversed sequence was introduced, i.e. 1 AAA to 999 YYY. The ever-increasing popularity of the car can be gauged by noting that these sequences ran out within ten years, and by the beginning of the 1960s, a further change was made in very popular areas, introducing 4-number sequences with the one and two letter area codes, but in the reverse direction to the early scheme (i.e. 1 A to 9999 YY). Often number plates were on hinges, as petrol tank caps were located under the number plates on some cars.

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
