Switzerland license plate, Provisional Z (documented since 1987), sample BS 829065Z

Format, years and the law

Format
LL 999999Z, for example BS 829065Z (L is any letter, 9 any digit)

The trailing Z makes it a Zollschild: the vehicle has not cleared Swiss customs yet. The ordinance prescribes the letter but never says where it goes, the trailing position every spotter knows is practice, not law.

Z
Zoll (customs, vehicle not yet cleared)

The format above follows the issuing rules: a registration that fits it is one this series could have issued.

Years issued
Documented since 1987; the format is likely older than the first year documented. Still issued.
Vehicle class
Temporary: short-validity plates (transit, awaiting registration). Issued for car, van, truck, bus, and motorcycle.
Colours
Characters #000000 Background #FFFFFF
