Finnish vehicle registration plate

Endpoint GET /v1/fi/vehicle-registration

What it covers

Returns a realistic Finnish vehicle registration plate. `type` selects the kind: `standard` (default, `LLL-NNN`, e.g. KOV-713), `custom` (vanity), `diplomatic` (`CD-NNNN`), `export` (`L-NNNN`), `dealer` (`KOE NNN-L`), `museum` (`M<L>-NNN`), `trailer` (D/P/W series), `military` (bare `NNNNN`), `motorcycle` (`LL-NNN`), or `aland` (`ÅL NNNNN`). On the standard plate, `era` chooses the modern `current` scheme or the shorter `legacy` 1960s–70s tails (`both` picks one at random). Finland carries no region and no checksum, so there is no `invalid` variant. Use `format` for hyphen, spaced, or compact rendering.

Parameters

ParameterTypeDescription
countinteger1–1000Number of records to return, 1–1000 (your plan may lower this). Omitted returns a single record; set it for a batch.
edgebooleanRestrict output to edge-case plates from the rare corners of the format.
era"current" | "legacy" | "both"Format generation for the standard plate: current (`LLL-NNN`), legacy (`LLL-N`/`LLL-NN`), or both (random). Ignored for other types.
extremebooleanReturn a correct value wrapped in a hostile encoding (untrimmed whitespace, invisible/zero-width characters, BOM, or bidi/combining marks). Homoglyphs are excluded so the value stays machine-parseable; it still validates after normalisation.
format"hyphen" | "with-space" | "compact"Plate rendering: hyphen (default), with a space, or compact.
invalidbooleanReturn a deliberately invalid value that fails validation, for testing rejection paths.
seedintegerInteger seed for reproducible output: the same seed always yields the same record.
type"standard" | "custom" | "diplomatic" | "export" | "dealer" | "museum" | "trailer" | "military" | "motorcycle" | "aland"Plate kind: standard, custom, diplomatic, export, dealer, museum, trailer, military, motorcycle, or aland.
