those are prefixes on UK licence plates which relate to the year the car was registered (usually) with the full number you can also find which region the car was from see

if you have not got the owners manual you can download it direct from Land Rover the workshop manual is available elsewhere online Derek
Prefix on the registration of the vehicle which identified the age of the vehicle unless some one has a cherrished number transfered to it.
On onlder Brit cars prior to a A Prefix (1983) then the letters which identified the age were a suffix
Example: G123 ABC - G = 1989 August to July 1990 car, 123 is a sequential number that the licencing office allocate.. i.e. the next would be 124, the A is meaningless and the BC would identify the local vehicle licensing office so you could tell where a car origionated from.
Older cars pre '83 had the suffix for the age rather like my 101 and Series IIa which are like ABC 123G
Some letters such as O Z I U were missed out incase they became confuse, yet now our current system inclueds Z's
Current system (just to confuse you further) is AB 01 DEF where as AB is the area ID 01 is the year and DEF is random, next would be DEG, DEH,DEJ and so on.
Half way through the year we also get new numbers so a 2006 car could be AB06CDE or later in the year if registered would be AB56CDE, then next year cars will be made up of AB07CDE and AB57CDE............. IYSWIM
