Guidelines

The Geo Adrescheck Nationaal is available in 1 form to implement the address verification in your tooling (webform, CRM etc).

The following method is defined within the Geo Adrescheck Nationaal.

1. 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 on of these subsets insteads 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.
