The most common format for vehicle registration plates in Romania consists of black letters on white background in the format CC 12 ABC, where CC is a two letter county code, 12 is a two digit group, and ABC is a three letter group. For Bucharest, the format is B 12 ABC or B 123 ABC, where B is code for Bucharest city, 12 and 123 is a two or three digit group, and ABC is a three letter group. The left side of the plate bears a blue vertical strip displaying the 12 stars of the European Union and the country code of Romania (RO). Between 1992-2007 the band featured the Romanian flag instead of the 12 stars. All lettering comes from the Latin alphabet.
