Austrian Steuernummer

Endpoint GET /v1/at/steuernummer

What it covers

Returns a format-valid Austrian Steuernummer (tax number), e.g. `12-345/6789`. The Steuernummer has no uniform checksum, so it is format-only — there is no `invalid` flag.

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 valid edge-case numbers from the rare corners.
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.
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.

Response fields
