Signs you should call 911 now
Short answer first, then the details: call 911 for a fire, a crime in progress, a serious injury, chest pain, trouble breathing, or any situation where someone’s safety is at immediate risk. When in doubt, dispatchers would rather you call and let them decide.
What the dispatcher will ask
The table below lists the numbers with their official source. Dispatchers follow a set order of questions so they can send the right help to the right place as fast as possible.
| Question | Why they ask | Your answer |
|---|---|---|
| Where are you? | Send help | Address or landmark |
| What happened? | Pick the service | One sentence |
| Is anyone hurt? | Send medics | Yes or no |
Called 911 by accident
Check the official source before relying on it. If you dial 911 by mistake, stay on the line and tell the dispatcher it was an accidental call; hanging up can lead to a callback or a welfare check at your location. Numbers and services can change. If unsure, dial the general emergency number shown on your phone’s emergency call screen.
