911 (emergency telephone number)

911, sometimes written 9-1-1, is an emergency telephone number for Argentina, Canada, Dominican Republic, Jordan, Mexico, Pakistan, Palau, Panama, the Philippines, Sint Maarten, the United States,^[2] and Uruguay, as well as the North American Numbering Plan (NANP), one of eight N11 codes. Like other emergency numbers around the world, this number is only intended for use in emergency circumstances. Using it for any other purpose (such as making false or prank calls) is a crime in most jurisdictions. Penalties for abuse or misuse of 911 can range from probation or community service to fines and jail time. Offenders can also be ordered to undergo counseling and have their use of telephones restricted or suspended for a period time as a condition of probation.

In over 98 percent of locations in Argentina, Sint Maarten, Panama, Belize, Anguilla, Costa Rica, Ecuador, Jordan, Ethiopia, Liberia, Saudi Arabia, Philippines, Uruguay, United States, Palau, Mexico, Tonga and Canada, dialing 911 from any telephone will link the caller to an emergency dispatch office—called a public safety answering point (PSAP) by the telecommunications industry—which can send emergency responders to the caller's location in an emergency. In approximately 96 percent of the United States, the enhanced 911 system automatically pairs caller numbers with a physical address.^[3]

In the Philippines, the 911 emergency hotline has been available to the public since August 1, 2016, starting in Davao City. It is the first of its kind in the Asia-Pacific region.^[4] It replaces the previous emergency number 117 used outside Davao City.

As of 2017, a 911 system is in use in Mexico, and Argentina where any implementation in different states and municipalities is being conducted. Venezuela also has a 911 emergency service called VEN911. As of 2023, it has been in operation for almost 10 years.^[5]
