Optional plates

Iowa offers its motorists a number of optional issue designs that are available upon the payment of an additional fee. Plates of all types other than the university types are available for both automobiles and motorcycles, the latter using a smaller overall plate size. University Plates are the only plates not colored the same as the standard issue plate, the color scheme is a yellow base, with the university's main sports team color on both the numbers, and a header denoting the school (i.e. red for Iowa State University, black for University of Iowa, purple for UNI, et cetera).
