What kind of information does the car number convey to us?

conveys information such as region and identity.

car owners make them according to their own preferences, and they all look different, not to mention the same size. Even at the beginning of the last century, when States began to issue official licenses, the sizes were different.

every state has its own standards, and even within the same state, it will be different with the increase of numbers. For example, a three-digit number plate is shorter than a four-digit number plate, and so on.

this chaotic situation didn't end until 1956, when all the automobile manufacturers in North America jointly applied to the government to unify the license plate size, so that a unified license plate rack could be used when designing automobiles. In this way, the license plate specification of 6x12 inches in North America was fixed and has been used ever since.
