from Wikipedia, the free encyclopedia

The authority number 115 in Germany gives you direct access to information about public administration services . The pilot operation of the telephone number 115, also known as the citizen hotline , started on March 24, 2009 in model regions. Regular operations began on April 14, 2011.

Telephone citizen services from municipalities as well as from state and federal authorities are networked under the short number 115 , so that information on administrative matters - for example opening times of various authorities, responsibilities for certain matters or information on topics such as marriage, childcare, naturalization, etc. - are all available under this number can be requested. 75 percent of the 115 calls are accepted by an employee within 30 seconds and 65 percent of the concerns should be answered directly on the first call, that is the service promise of the 115 network. Inquiries that cannot be processed immediately should be forwarded to the responsible contact person at municipal, state or federal level. The model for the authority number is the New York Citizen Service with the telephone number 311.


Planning for the D115 project began in spring 2007. In December 2007 the number 115 was assigned by the Federal Network Agency and in September 2008 the D115 detailed concept developed by experts from municipalities, states and the federal government was published. It defined the general conditions for the test operation and the subsequent pilot operation of the number.

On March 24, 2009, pilot operations began in several model regions, including Berlin , Hamburg , Oldenburg and large parts of North Rhine-Westphalia . Little by little, other regions were added. The pilot operation ended on April 14, 2011 and was thus transferred to regular operation.

In December 2009, the federal government and the central municipal associations agreed that the number 115 should in future be available throughout Germany. Since May 2019, the authority number can be reached nationwide in all federal states.

The XÖV standard, especially XZUFI, was developed for the systems, their communication and portals .
