Austrian house numbers are the source's labels and are returned as
strings, such as `"1"`, `"6-8"` or `"A"`. Every address from the
Austrian dataset carries its source `addressId` and, where the source
designates the building (`Wohnhaus`, `Hauptgebäude`, `Bau 1`), its
`buildingName`.

* When the fields describe several source addresses (several buildings
  at one house number, for instance), the response is a 400 that lists
  their `addressId` values; select one by its location or building
  name and retry with `addressId`.
* An `addressId` alone resolves that exact address. Fields sent along
  with it must match the selected address.


Austrian postalCode

The `addressId` of an address-level suggestion. It selects that one source
address, including an address without a house number, and is required when
the other fields describe several addresses. Any other field sent along with
it is checked against the selected address.

such as `"30"`, `"4.1"` or `"2bis.1"`. Every address from the Swiss
dataset carries its source `addressId` and, where the source names the
building, its `buildingName`. An address you added yourself through
[feedback](#tag/Feedback-CH) has no source record, so it carries
neither.

* When the fields describe several source addresses (two entrances of
  one house number, for instance), the response is a 400 that lists

strings, such as `"1"`, `"03"` or `"S-N"` (sin número). A padded number is a
different address from its unpadded spelling. Every address from the
Spanish dataset carries its source `addressId`; its `buildingName` is
always null, as the source names no buildings.

* When the fields describe several source addresses (two portals of
  one house number, for instance), the response is a 400 that lists
  their `addressId` values; select one by its location and retry with
  `addressId`.

### How it works

- Suggestions are generated from **postnames**.
  A postname is the official postal designation used by Bpost, which may differ from the administrative municipality or deelgemeente.
  For example, **Laken** is a postname within the municipality of **Brussels**.

- If the `languageCode` parameter is omitted, results are returned in the **country default language**.
- If the `languageCode` parameter is specified but no matches exist in that language, the API will fall back to the **country default language**.

- `postalCode` or `settlement` is required.


ISO 639-1 language code used to determine the language context for input filters.

- **When specified**: input filters are applied only within the given language.
- **When unspecified**: the **default value** is `'nl'` (Dutch).
