For the Dutch market requesting a 088 (enterprise number block) or 0800 (tollfree) number is different from the standard DID purchasing process via the Voice Management App. These numbers are so called company owned numbers and need to be purchased directly from the Dutch Telecom regulator (ACM). A certificate of ownership is received upon acceptance which is needed by CM to activate the number.
Step by step process:
!! 088-numbers can only be purchased in 100-block increments !!
0800 (tollfree) numbers: Visit https://www.acm.nl/nl/onderwerpen/telecommunicatie/telefoonnummers/informatienummers-aanvragen/voorbereiding-aanvraag-informatienummers (Dutch only) to start the online proces for the purchase of the number.
Send the received certificate of ownership together with the number information to email@example.com. Leadtime for the activation is 7 days (including weekends).
