The license plates of Mauritania feature a white background with a blue label.

The plates start with four digits, followed by two letters and end with a two-digit number.

This combination provides information about the specific area where the vehicle is registered (e.g., "00" for Nouakchott).

This includes a blue bar displaying a circular outline of the country and the distinctive "RIM" abbreviation (French: République Islamique de Mauritanie - Islamic Republic of Mauritania) in both Arabic and Latin letters.

In older license plates, the blue bar is not present, and only the letters are displayed.
