What Is 911?
Quick Answer
911 is the emergency phone number in the United States that connects you to help — like police, firefighters, or an ambulance — when someone is in danger or badly hurt. You can call it from any phone for free, and a trained person called a dispatcher will answer and send the right help to you. It should only be used in real emergencies, not for questions or non-urgent problems.
Explaining By Age Group
Ages 3-5 Simple Explanation
You know how when you need help, you go find a grown-up? Well, 911 is a special phone number that grown-ups — and even kids — can call when they need help really fast. If someone is very sick, if there is a fire, or if someone is in danger, calling 911 brings helpers like firefighters, police officers, or doctors in an ambulance.
When you call 911, a real person answers the phone. That person is called a dispatcher, and their job is to listen to you, find out what is wrong, and send the right helpers to where you are. They are really kind and really good at their job.
You should only call 911 when it is a real emergency — like if a grown-up falls down and cannot get up, or if you see a fire. You should not call it to ask questions or just to see what happens, because the helpers need to be ready for people who really need them.
One of the best things you can learn is your address — the name of your street and your house number. That way, if you ever need to call 911, you can tell the dispatcher where you are so the helpers know exactly where to come. Your mom, dad, or another grown-up can help you learn it.
Ages 6-8 More Detail
911 is the phone number you call in the United States when there is a serious emergency. It connects you to a dispatcher — a person whose job is to answer the phone, figure out what kind of help you need, and send police officers, firefighters, or an ambulance to your location. You can dial 911 from any phone, including a cell phone, and the call is always free.
There are three main kinds of emergencies where you would call 911. First, medical emergencies — like if someone is very sick, cannot breathe, or is badly hurt. Second, fires — if you see a fire in a building, in a car, or spreading through a field. Third, crimes or danger — if someone is breaking into a house or if a person is being hurt by someone else.
When you call 911, stay calm and answer the dispatcher's questions. They will ask things like "What is your emergency?" and "Where are you?" Try to give your address or describe where you are as clearly as you can. Stay on the phone until the dispatcher tells you it is okay to hang up, because they might need more information from you.
It is really important to only call 911 for true emergencies. Calling 911 as a joke or because you are curious ties up the phone line, and that means someone who truly needs help might not be able to get through. If you are not sure whether something is an emergency, it is always okay to ask a trusted grown-up first.
Every kid should know a few things that can help in an emergency: your home address, a parent's phone number, and how to unlock a phone to dial 911. You do not need a password to make an emergency call on most cell phones — there is usually an "Emergency Call" button right on the lock screen. Practice finding it so you know where it is.
Ages 9-12 Full Explanation
911 is the universal emergency phone number in the United States, and it has been in use since the late 1960s. When you dial 911, your call goes to a Public Safety Answering Point — basically a call center staffed by trained dispatchers who are available 24 hours a day, 7 days a week. The dispatcher figures out what kind of emergency you are dealing with and sends the right responders: police, fire, or medical.
The system is designed to work from any phone. Landlines automatically send your address to the dispatcher, which is one reason emergency calls from home phones are so effective. Cell phones send your general location using GPS and cell tower data, but the location is not always exact, which is why dispatchers still ask where you are. You can even call 911 from a phone that does not have an active phone plan — any cell phone with a charged battery can reach 911.
When you call, the dispatcher will ask a series of quick questions: What is your emergency? Where are you? Is anyone hurt? Are you safe right now? Your job is to stay as calm as you can and give clear answers. The dispatcher is trained to guide you through the conversation, and in many cases, help is already being sent while you are still on the phone. Do not hang up until the dispatcher says you can.
Knowing when to call 911 is just as important as knowing how. It is for life-threatening situations: someone having a heart attack, a house on fire, a car crash with injuries, someone in immediate danger. It is not for things like a lost pet, a noise complaint, or a question about homework. For non-emergencies, most areas have a separate non-emergency number you can call instead. Misusing 911 takes dispatchers away from real emergencies and can slow down response times for people who truly need help.
One thing a lot of kids do not realize is that they can be the ones to make a difference in an emergency. If a parent or grandparent collapses and no other adult is around, you might be the only person who can call for help. That is why it is worth being prepared: memorize your home address, know a parent's phone number, and understand what counts as a real emergency. Having that knowledge could save someone's life — and that is not an exaggeration.

Tips for Parents
911 can be a challenging topic to discuss with your child. Here are some practical tips to help guide the conversation:
DO: Practice, don't just discuss. Run through emergency scenarios: fire drills at home, earthquake drop-cover-hold, what to do if separated in public. Rehearsal builds muscle memory.
DO: Make sure they know key information. By age 5, children should know their full name, parents' names, address, and how to call 911. Practice this regularly.
DON'T: Don't create excessive fear. Frame safety knowledge as empowering, not frightening. 'You know what to do if...' is more helpful than 'Here's all the scary things that could happen.'
DO: Teach the concept of trusted adults. Help your child identify 3-5 trusted adults they can go to for help: parents, grandparents, teachers, neighbors. Practice scenarios where they might need to seek help.
DON'T: Don't assume one conversation is enough. Revisit safety topics periodically, especially after relevant news events or changes in routine (new school, new neighborhood).
Common Follow-Up Questions Kids Ask
After discussing 911, your child might also ask:
Can I call 911 from a cell phone that has no service plan?
Yes. In the United States, any cell phone with a charged battery can dial 911, even if it does not have an active phone plan or a SIM card. The call will still connect to a dispatcher. However, the dispatcher may not get your location as accurately, so be ready to describe where you are.
What happens if I accidentally call 911?
If you accidentally call 911, do not hang up. Stay on the line and tell the dispatcher it was an accident. If you hang up, they may try to call you back or even send police to your location to make sure everything is okay. It is not a big deal — just let them know it was a mistake.
Can I text 911 instead of calling?
In many areas, yes. Text-to-911 is available in a growing number of places across the United States. It is especially helpful for people who are deaf or hard of hearing, or for situations where making a voice call could put you in danger. However, calling is still faster and preferred whenever possible.
What information should I be ready to share when I call 911?
Try to know your location (home address or cross streets), what the emergency is, how many people are involved, and whether anyone is hurt. If you can, also describe what the people involved look like or what direction they went. The dispatcher will guide you through questions, so do your best and stay on the line.
Is 911 the same number in every country?
No. 911 works in the United States, Canada, and Mexico. Other countries have different emergency numbers — for example, the United Kingdom and much of Europe use 112, and Australia uses 000. If you are traveling, it is a good idea to learn the local emergency number before you go.
