Address lookup by postcode and house number

Get an address based on its unique combination of postcode, house number and house number addition.

Coordinate and surfaceArea values are null values if no location is known, i.e. if the address is a PO Box.

You must always check the houseNumberAddition result field, as a successful response is also returned if only the input addition isn't found.

URL template

The REST API requires GET requests. Parameters are added to the REST resource URL, and each parameter must be URL-encoded:

https://api.postcode.eu/nl/v1/addresses/postcode/{postcode}/{houseNumber}/{houseNumberAddition}

Example REST request

Retrieving /nl/v1/addresses/postcode/2012ES/30/ with the proper authentication would use the following HTTP Request:

GET /nl/v1/addresses/postcode/2012ES/30/ HTTP/1.1
Host: api.postcode.eu
Authorization: Basic 2eTpkU******…

Example response

The lookup is successful so we receive a 200 OK status in the headers:

HTTP/1.1 200 OK
Content-Type: application/json; charset=utf-8

And a JSON response in the body:
