Vehicle registration plates of Mexico are issued with unique visual designs by each state, but with one national numbering system, such that serials are not duplicated in multiple states. Most states change designs approximately every third year, with each state on its own plate replacement cycle. Every year owners Mexican plated vehicles pay the tenencia or revalidación de placas (car plates renewal tax). A set of Mexican plates includes one pair of plates, a windshield sticker, and in a few states a plate sticker.
In 2001 the size of the plate number was reduced in order to accommodate the addition of the state number, legend indicating the position of the plate on the vehicle (delantera (front) or trasera (rear)), and additional graphics.
European-style license plates have become popular, as with this example of an unofficial remake of a Baja California plate. Unofficial plates are legaloid: they remain technically illegal, but in practice they are tolerated. However, it should be noted that for most (all?) states you can choose between Euro style plates and the more common (US) style plates
The current 000-AAA plate series for Mexico City was introduced in 1972, allowing registration for 10,950,300 private automobiles. This series was not affected by plate designs, and continued to be used until its ending in early 2015 (999-ZZZ). However, in 2001 all vehicles using combinations around 000-LWU and older received all-new combinations beginning in 000-MAA. Following the established series, vehicles after 999-ZZZ are registered as A01-AAA, in order to not use a combination used in the past.
