Vehicle registration plates of Mongolia consist of four digits (including leading zeroes) and three Cyrillic letters. The design is reminiscent of the Soviet standard for licence plates in the former USSR (GOST 3207-77), some of which had four digits and three letters.
The design was updated in 2001 to include the national symbol (the "Soyombo") in red to the left of the numbers, and – between the digits and letters – the Mongolian IDL 'MNG' in an oval (despite 'MGL' being the official international identifier).
Since about 2018, many newly-produced licence plates have used the Roboto typeface in lieu of DIN 1451.
The first two letters of the three-letter suffix indicate the province (or aimag in Mongolian) where the vehicle was registered:
