In the United States, 911 is the phone number you call when you need help right away, as of November 2026; it is meant for an injury or an immediate danger. Say it as "nine-one-one", not "nine-eleven", so you look for the right buttons on the phone. A trained helper answers the call. That person asks what happened, where you are and who needs help; three digits are easy to remember. Behind them stand a long history and a large network of people and equipment, and both took years to build. Before 911, a person reporting a fire, an accident or a crime dialed a number for that kind of responder. The numbers were different in every community; dialing long numbers on rotary phones slowed things down. In January 1968, AT&T announced that it had chosen 911 as the emergency number, and the Federal Communications Commission supported the announcement. The number was short and easy to remember. It had also not been used as an area code or other code, so it fit phone systems.
The first 911 call in the United States was made on February 16, 1968, at about 2 p.m., in Haleyville, Alabama. Alabama House Speaker Rankin Fite dialed 9-1-1 from the mayor's office. U.S. Representative Tom Bevill answered on a bright red telephone at the police station. An independent phone company president, Bob Gallagher, had wanted a small town of about five thousand people to use 911 before AT&T did; he picked Haleyville because it had the right equipment and capable phone workers. 911 spread slowly. About seven hundred 911 systems worked ten years after Haleyville. It took thirty years for three-fourths of Americans to have 911 access. The Wireless Communications and Public Safety Act took effect on October 26, 1999, and made 911 the country's official emergency number. The system is run by local and state governments, not the national government. Their authority and duties vary from state to state.
The call centers are called Public Safety Answering Points, or PSAPs; in some, the same people receive, process and dispatch requests for help. In others, one team answers and another sends first responders. Some 911 professionals are certified as emergency medical, fire or police dispatchers, which means they had extra training to help callers in those kinds of emergencies. A new telecommunicator's training covers communication, the technology used to handle calls, and how fire, EMS and law enforcement respond to incidents; it also covers legal issues and ways to manage stress and stay healthy on the job.
During a call, the call-taker asks for the location of the emergency, including the street address; they also ask for the phone number you are calling from and what is happening. Details such as a description of a fire or of symptoms help too. Many 911 centers can tell callers exactly what to do until help arrives, such as step-by-step instructions to help someone who is choking or needs first aid or CPR. It is okay to trust the 911 operator and answer the questions. Basic 911 means that a call-taker at the local 911 call center answers when someone dials. The emergency and its location are told by voice. With Enhanced 911, as of November 2026, the call is routed to the right call center for the caller's location. The call-taker's screen shows the caller's phone number and address. NENA estimates that about 240 million calls are made to 911 in the U.S. each year, and in many areas 80% or more are from wireless devices. A phone that is not signed up with a carrier can still call 911. The call center does not get the caller's location, though, and cannot call back if the call is disconnected.
Text-to-911 is the ability to send a text message to emergency call takers; voice calls give call centers more information, so the FCC says always call if you can. As of November 2026, texting is only available in certain places, and each call center decides how and whether to accept texts. Where it is not available, the sender should get a bounce-back message. Not every problem is a 911 emergency; a prank call, or any call that is not an emergency, can slow help for someone who needs it. Too many of them can overload the 911 system. Local 911 centers have a separate phone number for things that are not an emergency. A grown-up can search online for it; do not call 911 to ask for it. If you call 911 by mistake, do not hang up. A hang-up could make the call-takers think there is an emergency and send help.
