ETO Numbering Reports

During the 1990’s, the former European Telecommunications Office (ETO) undertook several studies for the European Committee for Telecommunications Regulatory Affairs (ECTRA) of the means of improving the efficiency and effectiveness of numbering, naming and addressing from a regulatory point of view. This work, some of which was initiated at the request of the European Commission, was in response to the recognition that numbering is a key issue in a competitive environment to ensure easy access to networks and services. In parallel with these studies, the ETO also undertook several studies with regard to the establishment of a European Telephony Numbering Space (ETNS).

The reports of the studies listed below are available for download.
