Bolivia has a 50Hz grid, but some parts of the country operate at 110V while other parts operate at 220V. There is some mixing of the 2 voltages in some areas. I was in a room in La Paz where one side of the room was 110V and the other side was 220V, with the same type of receptacles and no markings!
