The Nevada Department of Motor Vehicles (DMV) has a Special Plates Unit in their Alternate Services office. Requests for Nevada license plates that are authentic in appearance to a particular year (for instance a plate for a 1925 car) can be requested by using the form which you will find through the link provided below. The DMV website for classic car registration notes that "[v]ehicles 1942 and older may use replica plates in the same colors and design as the plates issued in the year of manufacture. Please submit original plates if available to ensure the closest match." The DMV staff is knowledgeable and courteous, and you are encouraged to call the Special Plates Unit office at 775-684-4750 for more information. Your inquiries are welcomed.
