Vatican City license plate: CV (1988 to today)

Format, years and the law

Format: CV 99999, for example CV 71705 (9 any digit)
The format above follows the issuing rules: a registration that fits it is one this series could have issued.
Years issued: 1988 to today. Still issued.
Vehicle class: Standard: the default series issued to private road vehicles. Issued for car and van.
Colours: Characters #000000 Background #FFFFFF
About this plate: THE PRIVATE REGISTER, and the row the brief singled out. CV is granted by the Governatorato to "le auto di proprietà dei cittadini e delle personalità a cui è concessa l'immatricolazione nei ruoli vaticani", vehicles owned by citizens and by persons to whom registration in the Vatican rolls is granted. It is therefore a genuine STANDARD/private series with an eligibility gate, not an official one, and not a sub-range of SCV.
How numbers are issued: Progressive from a reported CV 03000 for private cars.
Format notes: Five progressive digits, as for SCV. The observed example "CV 03566" and the reported opening number "CV 03000" are both five-digit, and it.wikipedia and targheitaliane.it agree the private car series opened at CV 03000.
