Validate Dutch address data with the Postcodecheck API
PostNL offers the ability to validate the checkout process of consumers and improve the quality of CRM data.
With the Postcodecheck API you can ensure that your customers always fill in the correct address data. All they have to do is enter a postalcode and housenumber(+ housenumber addition) and its corresponding address appears automatically. If the address data (postalcode + housenumber) is incorrect, an error message will be shown.
