What is the Adrescheck Nationaal?
Achieve an efficient and correct input and check address data before it enters your software tooling, such as CRM and ERP system. Validate address data while it is entered.
How does the Adrescheck Nationaal work?
Simply use the API to check addressdata that is entered in your webshop or CRM.
The Adrescheck Nationaal is available in 2 different forms that differ on the input fields structure. The different methods provide an optimal way to implement the address verification in your tooling (webform, CRM etc).
General format (send any of a list of pre-defined fields). You can opt to require users to fill in a complete address (with all pre-defined fields that make up an address) or choose to choose a subset of fields. Unique Dutch addresses can be found based on the PostalCode+HouseNumber+Addition (dependant on the existence of an Addition in the HouseNumber range) or Street+HouseNumber+Addition+City. It can be attractive to use one of these subsets instead of requiring users to fill out a complete address format. To reduce the amount of fields the single line method can be, depending on your preference, even more attractive.
