So a car registered now (September 2012 – February 2013) will have the number 62 (=12 + 50).
A car registered in September 2008 – February 2009 has the number 58 (=08 + 50), and so on.
The first two letters are an area code, which refer to the DVLA office where the car was originally registered.
The two numbers are an age identifier, which tells you in which 6-month period the car was first registered. The numbers change every 6 months, in March and September.
The March codes are easy to remember as they follow the year of registration (so a car registered in March – August 2012 has the number 12, a car registered from March – August 2005 has the number 05, etc.).
For cars registered in September – February, the code is the year (as of September) plus 50.
” Asked by many people, many times, over many years…The current number plate system in Great Britain has been around since September 2001.
Northern Ireland has its own system which is quite different, but today we’re concentrating on the GB system (England, Scotland, Wales).
We’re also not going to discuss any of the previous number plate systems before 2001.
British number plates are arranged in the format of two letters, followed by two numbers, followed by three letters (eg – XX 00 XXX).
Therefore, it is possible to have an ‘old’ number plate on a ‘new’ car.
However, you cannot have a newer number plate code than the one allocated for that car’s date of registration.
(eg – you can have an ‘04’ plate on a ‘12’ car, but not a ‘12’ plate on an ‘04’ car.
