9-1-1 in the context of "Emergency services"

Emergency services and rescue services are organizations that ensure public safety, security, and health by addressing and resolving different emergencies. Some of these agencies exist solely for addressing certain types of emergencies, while others deal with ad hoc emergencies as part of their normal responsibilities. Many of these agencies engage in community awareness and prevention programs to help the public avoid, detect, and report emergencies effectively. Emergency services are often considered first responders, and typically have dedicated emergency vehicles.

Emergency services have one or more dedicated emergency telephone numbers reserved for critical emergency calls. In many countries, one number is used for all of the emergency services (e.g. 911 in many parts of the Americas, 999 in the United Kingdom, 112 in continental Europe, 000 in Australia). In some countries, each emergency service has its own emergency number (e.g. 110 for police, 118 for coast guard, 119 for fire and medical in Japan; 110 for police, 119 for fire, 120 for medical in China). Calls made to emergency services to report emergencies are called calls for service.

112 is a 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 nearly 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 historically 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, 999 in the United Kingdom and Hong Kong, and 000 in Australia).

An Amber alert (alternatively styled AMBER alert) or a child abduction emergency alert (SAME code: CAE) is a message distributed by a child abduction alert system to ask the public for help in finding abducted children. The system originated in the United States.

The Amber alert was created in reference to 9-year-old Amber Rene Hagerman, who was abducted in Arlington, Texas, on January 13, 1996, and found murdered four days later. Alternative regional alert names were once used; in Georgia, "Levi's Call" (in memory of Levi Frady); in Hawaii, "Maile Amber Alert" (in memory of Maile Gilbert); in Arkansas, "Morgan Nick Amber Alert" (in memory of Morgan Nick); in Utah, "Rachael Alert" (in memory of Rachael Runyan); and in Idaho, "Monkey's Law" (in memory of Michael “Monkey” Joseph Vaughan). Although the system was named for Hagerman, "AMBER" officially stands for "America's Missing: Broadcast Emergency Response", an example of a backronym.
