The person who answers a 911 call is a trained helper. The call-taker asks for the location of the emergency, including the street address, the phone number you are calling from, what is happening, and details such as a description of a fire or of symptoms. It is okay to trust the 911 operator and answer their questions.

911 call centers are called Public Safety Answering Points, or PSAPs. In some, the same people receive, process and dispatch requests for help, while 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.

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. The U.S. 911 system is run by local and state governments, not the national government. Their authority and duties vary from state to state.

Not every problem is a 911 emergency. As of November 2026, 911 is for a true emergency, when someone needs help right away. Local 911 centers have a separate phone number for things that are not an emergency. A grown-up can search online for the center's non-emergency number. Do not call 911 to ask for it. A prank call, or any call that is not an emergency, can slow help for someone who needs it, and too many of them can overload the 911 system.

Before 911, a caller reported fires, accidents and crimes by dialing numbers for specific responders. The numbers were different in every community, and dialing long numbers on rotary phones slowed things down. In January 1968, AT&T announced it had chosen 911 as the emergency number, and the Federal Communications Commission supported the announcement.

911 was chosen because it was short and easy to remember, and because it had 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, in Haleyville, Alabama, at about 2 p.m. Alabama House Speaker Rankin Fite dialed 9-1-1 from the mayor's office in Haleyville. U.S. Representative Tom Bevill answered on a bright red telephone at the police station.

The National Emergency Number Association, known as NENA, estimates 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, as of November 2026. A phone that is not signed up with a carrier can still call 911. But the call center does not get the caller's location and cannot call back if the call is disconnected.

Text-to-911 is the ability to send a text message to 911 emergency call takers. Voice calls give call centers more information, so the FCC says always call if you can, as of November 2026. Text-to-911 is only available in certain places, and each 911 call center decides how and whether to accept texts. Where it is not available, the sender should get a bounce-back message.

Two small habits help the call go well. Say the number as nine-one-one, not nine-eleven, so you look for the right buttons on the phone, as of November 2026. And 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.

The Red Cross first aid steps say: check the scene and the person, call 9-1-1 and get equipment if needed, then give care based on what you found and your training. Call 9-1-1 if a person does not respond, is not fully awake, is not breathing or only gasping, or has life-threatening bleeding. If a cut keeps bleeding after 15 to 20 minutes of pressure, get medical care or call 911.

In a fire, a room can go from bright to black. Fire starts bright, but quickly makes black smoke and complete darkness. Fire gases can make you dizzy and sleepy. If you cannot get out of a room, close the door, cover the cracks and vents with cloth or tape, and signal for help at the window with a light-colored cloth or flashlight. Dispatchers send firefighters to the address the caller gives, which is why a home address is worth knowing by heart.
