In the US license plates formats numbers may be consistent each the state. There is no such thing as ‘US license plates’ as they vary from state to state. In most cases, the vehicle numbers assigned in ascending order, and beginning with a starting point such as AAA-001, begin with big letter and continue with digits. The total number of symbols in small states is usually 4-5 and 6-7 in large ones, because there are more cars. Apart from the number, the license plate may contain the state name of vehicle registration.
There is much variety to the license plate series in the USA. Some series have a space after the second or first symbol, others may have a hyphen. There also are series where only letters are straight, one after the other, without separators. The first symbol in the plate is always a letter; the second may be a number or letter. You can learn more about a particular series by looking up the first two symbols. Please select the first 2 characters of license plate US.
