Business phone numbers in the Netherlands

The Netherlands is comparatively foreign-business friendly. An 0800 or geographic number can be requested with a foreign trade-register extract, though large-enterprise 088 blocks require Dutch KVK registration. Porting runs a fast 1 to 5 working days.

Porting

ACM regulates porting through a central number-portability database. The current holder submits the first part of the transfer application, and ACM emails the gaining holder a link that must be completed within 10 working days or the transfer auto-rejects, as of July 2026.

Mobile numbers typically port within 1 working day once confirmed, since the losing provider must issue a port code within 1 working day. Fixed and business-line porting typically takes 1 to 5 working days, though physical line delivery can extend it.

Foreign-registered businesses can port or request numbers using an extract from their home-country trade registry instead of a KVK number, with the same signing options as domestic applicants.

Requirements

·Foreign businesses can request Dutch numbers, including 0800 information numbers, directly using a foreign trade-register extract, as of July 2026.
·Registering in the Dutch Business Register (KVK) generally requires a Dutch address, with a narrow exception for border-region entrepreneurs proving structural Dutch activity from a foreign address.
·088 number blocks specifically require KVK registration; other ranges such as 0800 do not, per ACM's published rules.

Compliance notes

·Emergency number is 112. ACM's policy rule, in effect since 1 July 2021, requires every mobile calling technology including VoIP and Wi-Fi calling to reach 112 with location data, as of July 2026.
·Call recording is one-party consent for participants under Dutch criminal law (Art. 139a Wetboek van Strafrecht targets non-participant eavesdropping, not participant recording). GDPR still requires a documented legal basis, purpose limitation and disclosure to the other party.
·Recording risk in the Netherlands is civil and regulatory under GDPR rather than criminal, unlike Germany's Sec 201 StGB exposure.
