Nem igazán egyedi, mint egyedi, hanem a Vatikáni Városállam rendszámai ilyenek. Wikipédiából:
"The vehicle registration plates of Vatican City all begin with the letters "SCV", abbreviation of the Latin Status Civitatis Vaticanae ("Vatican City State"), followed by the vehicle fleet number. The registration plate for the Ford Focus currently used by Pope Francis is "SCV 00919".[2] In the past, the popemobile has typically used registration plate "SCV 1", although plates numbered "SCV 2" to "SCV 9" have also been used."
