The letters "PM" on a license plate refer to "permanent" registration. This is a relatively new type of non-numerical registration sticker that has been introduced in Florida, primarily for rental car companies. The PM decal is yellow and is printed in place of the month and year expiration. The paper registration will also have "Permanent Decal Issued" printed on it. The PM tag on the license plate means that the vehicle is permanently registered, and the owner does not have to renew the registration throughout the year. It is convenient for fleet owners to register their cars, as they dont have to redo the process once the registration expires. However, it is unlikely that individuals will be able to get the same treatment unless they own a similar business. The PM tag on the license plate has many benefits, such as making it easier to identify the vehicles purpose and giving the company an easy time in handling its fleet logistics.
