The first information you would get from a plate is the locality of the vehicle. To elaborate, with the number series of the vehicle, we would be able to identify the region and the local DVLA office where it was registered in. The information can be found by a car plate check.
A number plate, generally, is made of 3 parts. The first part is 2 letters, the second part is 2 numbers, and the third part is 3 letters. The first 2 letters refer to where it was registered, i.e., the first letter refers to the region, and the second letter refers to the local DVLA office. The second part is the age identifier, and those numbers change once every six months. The third part is the randomly chosen letters, and they provide the vehicle with its unique identity.
