Autocomplete addresses using one single API

With the International Address API of Postcode.nl you are assured of error-free addresses in your webshop and company. All your customers can enter their address faster using the autocomplete function. This way you can recognise and correct incorrect addresses before you actually start using them in your system.

You can use the address completion in your website or office system, but there are more possibilities. The API uses smart technology that can detect and correct spelling errors.

Ultimately you really save a lot on costs, not only address entry is much faster, you also save on the costs of maintaining address files in your current system.

Address data of multiple countries

In addition to Dutch addresses, Belgian, Luxembourg, German, Austrian and Swiss addresses can also be added. We are constantly working to further expand the number of countries.
