011
- 011 This number range is designated as "free" in the official lists of the Federal Network Agency, with the exception of (0) 115 (uniform authority number, international access) and (0) 116xyz. It is used (also) to phone numbers of the alley 116 in E.164 - Numbering Space mapping, so that they can be selected (at + 49-116-xyy) from abroad.
- 0116xyz with x = 0, 1 and y, z = 0… 9 Harmonized services of social value (international access)
- 0116116 Emergency lock call (does not count among the harmonized services of social value )
The uniform authority number 115 (for other places) cannot be reached under 0115, but under 0- area code -115 (or from abroad via + 49-area code [without leading zero ] -115 ).
In the past, value-added services were located here .
012
- 012 New services
- Companies that wanted to offer a new type of service that excluded the use of other number spaces of the national numbering space for the public telephone network / ISDN could apply for the allocation of numbers for new types of services. Numbers for innovative services were assigned to seven companies. All assignments have now expired. In the last five years, no more assignments have been made, as those interested in 012 numbers were able to use numbers for premium services or national numbers due to their business models. The following numbers were most recently assigned by the Federal Network Agency :
- 012-3000 Innovative Services: 3U Telecom , Marburg, no longer active (since May 2009), allocated until February 13, 2011
- 012-12 UMS number: GMX , no longer active (moved to 032 )
- 012-12 Innovative services: Web.de , Karlsruhe, between € 0.12 and € 1.86 per minute, no longer active (moved to 032 )
- The area code was created in 2001 in order to be able to provide customers with a local network-independent number, for which the area code 032 is now used.
013
- 013 voting and competition numbers:
- 0130 formerly Freecall (moved to 0800 )
- 0137, 0138 mass transportation services to certain destinations ( MABEZ ) - televoting, contests (Note: prices are for selecting a landline; in mobile phone tariffs different price structure, usually higher prices) (shift to 0500 planned)
- 01371 MABEZ: € 0.14 per call
- 01372 MABEZ: € 0.14 per minute
- 01373 MABEZ: € 0.14 per minute
- 01374 MABEZ: € 0.14 per minute

015

- Note: The numbers are originally assigned to a specific provider, but can be taken by customers to other providers as part of the number portability . A number is therefore not necessarily operated in the specified network.
