  • List of emergency telephone numbers


    An emergency phone on the Welsh coast at Trefor The following is a non-exhaustive list of emergency telephone numbers by country. Emergency telephone numbers are short, mostly three-digit numbers that can be easily remembered and quickly dialed. The concept was first introduced in London in 1937 using the number 999. This followed a fire in Wimpole Street which killed five women. A neighbour had tried to phone the fire brigade but was kept waiting by the operator. He wrote a letter to The Times and the government then took action. The 9-1-1 equivalent was first introduced in Winnipeg in 1959 and then adopted by the US in 1968, with the first call being made in Haleyville, Alabama. Some countries have different emergency numbers depending on the service.

  • Public safety answering point


    Public-safety answering point in Kraków, Poland A public-safety answering point (PSAP), sometimes called "public-safety access point", is a call center in Canada and the United States responsible for answering calls to an emergency telephone number for police, firefighting, and ambulance services. Trained telephone operators are also usually responsible for dispatching these emergency services. Most PSAPs are now capable of caller location for landline calls, and many can handle mobile phone locations as well (sometimes referred to as phase II location), where the mobile phone company has a handset location system. Some can also use voice broadcasting where outgoing voice mail can be sent to many phone numbers at once, in order to alert people to a local emergency such as a chemical spill. In Canada and the United States, the county or a large city usually handles this responsibility. As a division of a U.S. state, counties are generally bound to provide this and other emergency services even within the municipalities, unless the municipality chooses to opt out and have its own system, sometimes along with a neighboring jurisdiction.

  • 9-1-1


    A dispatcher takes an emergency call at the Jackson, Tennessee 9-1-1 Dispatch Center. Implementation of the two ITU approved emergency telephone numbers in the world:9-1-1, also written 911, is an emergency telephone number for the North American Numbering Plan (NANP), one of eight N11 codes. Like other emergency numbers around the world, this number is intended for use in emergency circumstances only, and using it for any other purpose (such as making false or prank calls) is a crime in certain jurisdictions. In over 98% of locations in the United States and Canada, dialing "9-1-1" from any telephone will link the caller to an emergency dispatch office—called a public-safety answering point (PSAP) by the telecom industry—which can send emergency responders to the caller's location in an emergency. In approximately 96 percent of the U.S., the enhanced 9-1-1 system automatically pairs caller numbers with a physical address. In the Philippines, the 9-1-1 emergency hotline has been available to the public since August 1, 2016, although it was first available in Davao City. It is the first of its kind in Asia-Pacific region.
