O number plates: Oxford area codes
A current number plate starting with O was first registered in the Oxford region. All 23 O memory tags belong to the Oxford office area, so the second letter does not narrow it down further.

Area code questions
Where is an OA number plate from?
OA plates come from the Oxford office area, in the Oxford region. The memory tag shows where the car was first registered, not where it is kept now.
Does the area code tell you where the car has been kept?
No. The memory tag is set when the car is first registered and stays with the registration, so a car can be kept anywhere in the country for its whole life. A private plate can also carry a memory tag from anywhere.
What do the other parts of the number plate mean?
The two numbers after the memory tag are the age identifier, which shows when the car was first registered, and the last three letters are chosen at random so that every registration is unique.
