Personalised Number Plate Information

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

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.
