112: single EU emergency number
112 is the European emergency number you can dial free of charge from fixed and mobile phones everywhere in the EU. It will get you straight through to the emergency services - police, ambulance, fire brigade.
National emergency numbers are still in use too, alongside 112. But 112 is the only number you can use to access the emergency services in all EU countries.
112 is also used in some countries outside the EU - such as Switzerland and South Africa.
