Member States shall take all necessary measures to ensure that as from the 31 August 2007 the competent National Regulatory Authority can assign the numbers referred to in the Annex.

The listing of a specific number and the associated harmonised service of social value does not carry an obligation for Member States to ensure that the service in question is provided within their territory.

Once a number has been listed in the Annex, Member States shall make known at national level that the specific number is available for the provision of the associated harmonised service of social value, and that applications for the rights of use for this specific number may be submitted.

Member States shall ensure that a register of all harmonised numbers, with their associated harmonised services of social value, available in their territory is maintained. The register shall be easily accessible to the public.
