Do all countries use vehicle country codes on number plates?

No. While many countries display vehicle country codes directly on the registration plate, others rely on separate identifiers, national emblems, flags or registration formats instead.

In Europe, vehicle country codes are commonly displayed alongside the registration number, often within the blue EU identifier strip. In other parts of the world, the country code may appear on a separate international registration sticker, be incorporated into the plate design or not be displayed at all. This is why identifying a foreign number plate often requires looking at both the vehicle country code and the registration format itself.
