________________________________________________________________________

The current day graphic license plates of Mexico incorporate the use of bar codes along with a new numbering system that uses hyphenated number and letter combinations.

These plates also bear the words TRASERA or DELANTERA, the first one being the plate for the rear of the vehicle and the latter being the plate for the front of the vehicle. This is a preventative measure designed so as motorists do not use both plates of a pair on two distinct vehicles.

Notice that next to the state name on the license plate is a jurisdiction code which run from 01 through 32. These numbers correspond to the particular state's name when all the states are listed in Spanish and in alphabetical order. Every license plate also features a vehicle designation and classification below the state name. The designation TRANSPORTE PRIVADO or PARTICULAR is used for private automobiles.

The bar code on the plate corresponds to the registration number for all 31 states with the exception of the Federal District (Distrito Federal) whose bar code actually corresponds to the vehicle identification number (VIN) to which it is registered.

On each Mexican license plate appears a small security seal within a small star. This security seal bears the letters SCT which stands for SECRETARIA DE COMUNICACIONES Y TRANSPORTES or the Department of Communications and Transportation.
