what year does the various reg numbers represent in britain?

Answer 1

New style. the first 3 letters are the district of registration, the 2 numbers the year and part (first part 2002 =02, second = 52) and the 3 letters are sequentially assigned as cars are registered from AAA to XXX, allowing 17000 possible combinations ( excluding a few like BUM &c.)
Old style. the 3 letter group gave the district (two letters + modifier so VKL was Kent (KL) and V indicating they had used the KL000 sequence many times. the numbers were sequentially assigned, and the year( and part) was assigned a letter. They went thru the letters twice ABC123P was 1975,
P123ABC was 1997. Some letters weren't used to avoid confusion (0-O, I-1,) and some like Q were kept for special cases.

Answer 2

The number starts with a 0 for May and a 5 for September of each year. 01, 51, 02, 52, 03, 53 etc.

Answer 3

They used to run from 1st Aug to 31st July.

The previous style started with the suffix 'A' through to 'Y'.
Then prefix 'A' to prefix 'Y'. However, 'T' was introduced in March 1999 to use up the letters in time for the new style plates, introduced September 2001.

51 = 1st Sep 01 to 28th Feb 02
02 = 1st Mar 02 to 31st Aug 02
52 = 1st Sep 02 to 28th Feb 03
03 = 1st Mar 03 to 31st Aug 03 and so on

Letters never used "I,O,U,Z". 'Q' was only used for handbuilt or other vehicles registered in different circumstances.

So to work it back, Y = Mar 01 to Aug 01
X = Sep 00 to Feb 01 W = Mar 00 to Aug 00
V = Sep 99 to Feb 00 T = Mar 99 to Aug 99
S = Aug 98 to Feb 99 R = Aug 97 to July 98
P = Aug 96 to July 97 N = Aug 95 to July 96

Hope this is of some use!!!!
