Number Management
Number Management is responsible for structuring the national numbering space, setting the conditions for allocating and using numbers, and processing applications for numbers and number blocks.
Telephone numbers
Telephone numbers are numbers which, when dialled in the public telephone service, allow a connection to a specific destination to be set up. Some numbers are character sequences which are used only for technical addressing purposes and which cannot be dialled by subscribers.
The German numbering space is the part identified by the country code 49 of the international numbering space as defined in Recommendation E.164: „The international public telecommunication numbering plan“ and is regulated in the Numbering plan for the numbering space for public telecommunications.
