Postcode API

Germany - Autocomplete a postal area

Get a list of postal areas matching the specified city name or postcode. A city identifier is returned for every match. This identifier can be used as a parameter to the completeStreet method.

The result field `cityAddition` is set to better tell apart cities that have the same name. This can be a municipality name or another type of human readable additional identifier. For example there are multiple cities named "Neuenkirchen", with different `cityAddition` values, such as: "Nordrhein-Westfalen", "Heidekreis" or "Landhagen".

The result field `postcode` is set when a postcode was matched in the input. It should be used as an additional parameter to the `completeStreet` method in order to narrow down the intended postal area.

The result field `matchedName` is set when a name other than the official city name has been matched. This can be a district or town name inside the matched city. For example the town "Alt Stassow" is a village that is a district of the city "Grammow".

We suggest presenting matches to end users in a format similar to: '{postcode} {cityName} ({matchedName or cityAddition})', where `postcode`, `matchedName` and `cityAddition` are optional depending on the match.

Please note that some postcodes exist in more than one city. An example is postcode 01561, occurring in both cities "Krau├čnitz" and "Lampertswalde".

URL template

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