Currently for Romania, ISO 3166-2 codes are defined for 41 departments and 1 municipality. The municipality Bucharest is the capital of the country and has special status equal to the departments.
Each code consists of two parts, separated by a hyphen. The first part is RO, the ISO 3166-1 alpha-2 code of Romania. The second part is either of the following:
one letter: municipality
two letters: departments
The letters are currently used in vehicle registration plates.
