1-1-2

112 is the common emergency telephone number that can be dialed free of charge from most mobile telephones and, in some countries, fixed telephones in order to reach emergency services (ambulance, fire and rescue, police).

112 is a part of the GSM standard and all GSM-compatible telephone handsets are able to dial 112 even when locked or, in some countries, with no SIM card present. It is also the common emergency number in all member states of the European Union as well as several other countries of Europe and the world. 112 is often available alongside other numbers traditionally used in the given country to access emergency services. In some countries, calls to 112 are not connected directly but forwarded by the GSM network to local emergency numbers (e.g., 911 in North America or 000 in Australia)

112 is not always supported by VoIP operators or on non-GSM networks.

112 was first standardised by a Recommendation by the CEPT in 1972 and later by a decision of the EU Council in 1991 and subsequently reaffirmed in 2002 by article 26 of the Universal Service Directive and its subsequent amendments.

This choice of number has the following advantages:

The countries which use the 112 number for emergencies include:

In many countries, emergency numbers previously used also continue to be available; e.g. 061 and 112 in Spain, 999 and 112 both function in the UK. In the United States, only some carriers, including AT&T will map the number 112 to its emergency number 9-1-1.
