Belarusian vehicle registration plates are currently composed of four digits, two letters and another digit (e.g. 1234 AB-5). The first of the letters and the final digit indicate the region of Belarus in which the car was registered. Vehicles owned by foreign companies use black-on-yellow plates, and the numbers and letters appear in a different order (e.g. M 1223). The diplomatic series uses white letters on a red background, also in a different order from standard plates (e.g. CD 1234-5).
