The CTU administers numbers for electronic communication networks and services using a numbering plan in order to ensure the administration and purposeful use of numbers, number ranges and codes, addresses and names (excepting Internet addresses) (hereinafter referred to as “numbers”). The numbers from numbering plans may only be used based on authorisation to use numbers. The award of authorisation to use numbers is governed by:
The numbers according to numbering plans may only be used based on authorisation to use numbers. Based on an application lodged with the Office, the Office decides on the awarding of authorisation to use numbers to any business undertaking ensuring a public communication network or providing a publicly available electronic communication service according to general authorisation or using such network or service in accordance with the terms and conditions ensuring the purposeful use of numbers. In the case of authorisation to use numbers connected to private communication networks, the Office is also authorised to award such authorisation to a legal person that is not a business undertaking according to the first sentence. In the cases of harmonised European numbers, the Office decides on awarding authorisation to business undertakings which ensure a public communication network or provide a publicly available electronic communication service or to a legal person not undertaking business whose activity corresponds to the purpose for which these numbers are reserved.
