Area code lookup
Geographical (fixed) telephone numbers are linked to a geographical area in the Netherlands. We offer, in cooperation with the Dutch regulator ACM, an information service to determine the area code associated with an address. This information service can be used by telecom providers to assign a geographical (fixed) telephone numbers to a customer and / or to determine whether a number can be retained when a subscriber moves.
This information service is also available through an API.
