About this plate: CICLOMOTORS (mopeds). A distinctive little plate, blue border, the legend ANDORRA in blue on a yellow panel, and the flag shield at the bottom left rather than the national arms at the top left. It is the one Andorran series that does not follow the common layout.
Format notes: FIVE DIGITS, mopeds kept the numeric grammar the car series left behind, and run their own independent number space from 00000 to 99999. So a five-digit Andorran plate today is a moped, while a five-digit plate from before the lettered stage was a car. The same string, two meanings, separated only by the plate it is printed on and by era.
