Courtesy plates have been issued to individuals with political connections since 1920. The current serial formats on these plates consist of three letters followed or preceded by a number between 1 and 20. On standard courtesy plates the first letter is a county code, the second letter is the first initial of the vehicle owner's name, and the third letter is the initial of the last name of the vehicle owner. Courtesy plates may also be personalized, with all three letters making up the owner's initials. Courtesy plates can be used on several types of vehicles, including cars, motorcycles and historic vehicles. They must be approved by a
NJ State Senator from the applicant's election district prior to being submitted to the MVC. The staff for the applicant's senator must also get approval from the state senator from the county that corresponds to the first letter on the plate being requested. The letter Q cannot be used on these plates, and D, O, T, and X cannot be used as the first letter.
