Finland test data, valid by format

Finnish person

Returns a synthetic Finnish person: given name(s), surname, initials, birth date, and the matching HETU. Constrain with `sex` and age/birth-date filters (contradictory combinations are rejected with a 400). Set `invalid=true` for a deliberately wrong check value, `edge=true` for rare-corner values, and `caseStrict=false` to mangle the name casing.

Finnish henkilötunnus

Returns a valid Finnish henkilötunnus (HETU, personal identity code) with a correct check character. Constrain with `sex` and age/birth-date filters (the full birth date and sex are encoded). Contradictory combinations are rejected with a 400. Set `invalid=true` for a deliberately wrong check character.

Finnish Y-tunnus

Returns a valid Finnish Y-tunnus (business identity code) with a correct mod-11 check digit. Use `format` for the FI VAT number. Set `invalid=true` for a Y-tunnus with a deliberately wrong check digit.

Finnish company

Returns a consistent synthetic Finnish company in one call: a full trading name with its legal form, plus the matching yTunnus. Shape the name with `strategy` and `legalForm` (as on `/v1/fi/company-name`). Set `invalid=true` to corrupt the checksummed identifiers (the name stays intact), for testing checksum validators.

Finnish IBAN

Returns a valid Finnish IBAN with a correct checksum. Pin the issuing bank with `bankCode` (6-digit bank code) or `bankName` (mutually exclusive), or let it be chosen at random. Set `invalid=true` to get an IBAN with deliberately wrong check digits, for testing checksum validators.

Finnish email address

Returns a realistic synthetic Finnish email address: a name-based local part (romanised to ASCII) on a free webmail, a Finnish regional provider, or a corporate domain built from a Finnish company brand. `domain` pins an exact domain; `domainCategory` (`free`/`regional`/`corporate`/`any`) scopes a weighted-random draw. `pattern` selects the local-part shape or `any`. `plusTag` controls plus-addressing; `exotic=true` allows the rarer RFC-valid characters.

Finnish vehicle registration plate

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.

Finnish product or service offering

Returns a realistic synthetic Finnish offering — a product or service with a localized name, a plausible EUR price, its unit, and its industry label. Finnish is multilingual: without a pinned `language`, names draw from the weighted fi/sv mix. Pin `industry` (NACE code), `type` (product/service), or filter by `industryName`/`offeringName` full text. Set `edge=true` for the price/format corners, `extreme=true` for a hostile-encoded name, or `invalid=true` for a broken record.
