Vehicle registration plates of Kenya

The current series of vehicle registration plates in Kenya are on a white plate with black lettering and look quite similar to UK suffix style registrations. The format is LLL NNNL, where ‘L’ denotes a letter and ‘N’ denotes a digit. The older series of number plates were black with white or silver lettering. Later in the older series the front plates were reflective white with black lettering and the rear plates were reflective yellow with black lettering. According to Kenya National Bureau of Statistics there are over 1,626,380 vehicles in Kenyan road as at 2011.

A serial number of 1-9999 followed, on white on black plates, save for public transport vehicles, ie buses, taxis and hire cars, which used black on white.
