An ENUM domain costs €1 per month.

However, in addition to the domain cost, there are additional costs for the “validation” of your domain/phone number. (Validation is an important process – see ‘Validation’ section below). These fees are €25 for the initial validations and €5 for any further validations. A repeated validation (“revalidation”) is necessary half-yearly – so there is a complete price of €42 for the first year and €22 for the following years. All prices include VAT.
