The two most important emergency numbers in Germany are 110 and 112. Dial 110 to reach the police, regardless of whether you are calling from a landline or a mobile phone. You should call this number if you are being threatened, are in an emergency situation or want to report a crime. Dial 112 to be connected to the fire brigade and emergency medical services. There you can report fires and request medical help in the event of accidents.
116117 is the number of the medical on-call service. There you can get medical advice outside regular practice hours for urgent but non-life-threatening complaints. And at 116116, you can have bank, credit or SIM cards blocked free of charge if they are lost or stolen.
