What are the advantages of 115?
Calling 115 saves time, is uncomplicated and reliable:
Citizens no longer have to spend much time finding responsible authorities and their phone numbers. Most questions can be answered directly so that the caller need not address the same request a second time to public administration. Unnecessary visits to public authorities can thus be avoided.
Furthermore callers no longer have to look further if they do not get an answer directly on the phone: They will be called back. Moreover, the service is not expensive. 115 can be reached from German landlines and from mobile phones at local rates and hence free of charge if the caller has a flat rate.
