To reach the police, call 911 when there is an immediate threat to life or property, a crime happening right now, a serious injury, or a fire. For anything less urgent, call your local police department’s non-emergency line or, in many cities, dial 311. That single choice, emergency versus non-emergency, decides how fast help arrives and whether you’re tying up a line someone else may need to save a life.
When 911 Is the Right Number
Dial 911 whenever someone’s safety is at immediate risk or a crime is actively unfolding. Violent confrontations, building fires, crashes with injuries, medical emergencies like a heart attack or stroke, and break-ins at an occupied home all belong on the emergency line. The common thread is urgency: something bad is happening right now, and a delayed response could lead to serious harm.
If you’re unsure whether your situation qualifies, call anyway. Dispatchers are trained to assess what’s happening and decide whether police, fire, or medical crews need to respond. A genuine but borderline call is never a problem. What causes real harm is hesitating during an actual emergency because you’re worried about overreacting.
When to Use the Non-Emergency Line
Non-emergency numbers exist for situations that need police attention but don’t involve immediate danger. A car break-in you discovered this morning, a noise complaint, a question about a local ordinance, minor property damage: the crime is already over, nobody is in danger, and a few hours’ delay won’t change the outcome.
You can find your local non-emergency number on your police department’s website, or by dialing 311 in cities that offer that service. Many departments also accept non-emergency reports online, which is useful for things like a stolen package or vandalism where there’s no suspect information and no one was hurt. Not every type of crime qualifies for online reporting, so check your department’s site for eligible categories.
Mental Health Crises: When to Use 988 Instead
Since July 2022, dialing or texting 988 connects you to the Suicide and Crisis Lifeline, a nationwide service staffed by counselors trained in mental health emergencies. It’s available 24/7 for anyone experiencing suicidal thoughts, emotional distress, substance use crises, or any mental health situation where they need someone to talk to.1SAMHSA. 988 Frequently Asked Questions
The response is different from 911. A 988 counselor provides crisis de-escalation and emotional support over the phone, and for most callers, that resolves the situation without dispatching anyone. If the counselor determines there’s an immediate physical safety threat, they can contact 911 on your behalf.2SAMHSA. What is 988 Call 911 directly when someone has already harmed themselves, is unconscious, or when the situation involves violence. Call 988 when the crisis is emotional or psychological and there’s no immediate physical danger.
What to Have Ready When You Call
The single most important piece of information is your location. Give the street address if you know it, or describe cross streets, landmarks, and what the building looks like. Cell phones transmit some location data automatically, but not always precisely enough for responders to find you quickly, so confirm your location out loud.
The dispatcher will also ask about what’s happening and who’s involved. Be ready to describe:
- What happened, whether it’s still happening, and whether anyone is injured.
- People involved: appearance, clothing, and which direction they went if they left.
- Vehicles: color, make, model, and license plate if you caught it.
- Whether you saw or suspect any weapons.
You’ll be asked for your name and callback number. If you’d rather not give your name, say so. Most departments accept anonymous reports, though providing your identity helps if officers need to follow up. The dispatcher may give you instructions while you wait: perform basic first aid, lock a door, move to a safer spot. Follow them even if they feel counterintuitive.
Stay on the line until the dispatcher tells you to hang up. In most systems, officers are already being dispatched while the dispatcher is still talking to you. When they arrive, keep your hands visible, stay calm, and follow their directions. If you called from inside a building, meeting officers at the door or having someone direct them speeds things up.
After the response, ask for the case number or incident report number. That number is essential for filing an insurance claim, following up with detectives, or referencing the incident in any legal proceeding. If you file online, most departments email a tracking number first and assign an official report number once the report is reviewed.
If You Accidentally Dial 911
Don’t hang up. Stay on the line and tell the dispatcher it was a mistake. Hanging up forces a callback or, worse, officers dispatched to check on you because they can’t confirm you’re safe. A quick “I’m sorry, this was an accidental call, everyone is fine” takes ten seconds.
If You Don’t Speak English
911 call centers use interpreter services. When you reach a dispatcher, say the name of your language and the dispatcher will connect a phone interpreter. The process adds some time but works reliably. Real-time translation for text-to-911 is still being developed, so a voice call will get you an interpreter faster than a text.3Homeland Security.

TTY, TDD, and 711
The Americans with Disabilities Act requires all 911 call centers to provide direct access for people using teletypewriter (TTY) devices, meaning the call center answers the TTY call itself rather than routing it through a relay service.4Federal Communications Commission. Access for 9-1-1 and Telephone Emergency Services For non-emergency calls, dialing 711 connects you to a telecommunications relay service where a communications assistant can place calls on your behalf.5National Institutes of Health. Telecommunications Relay Services
Calling from a Cell Phone, Hotel, or Office
You can call 911 from a cell phone even without an active service plan or SIM card. FCC rules require wireless carriers to connect any 911 call to the nearest emergency center regardless of account status. An old phone kept charged in a car or bag specifically for emergencies will still work.
Cell phone location tracking has improved. Under current FCC rules, nationwide wireless carriers must provide a caller’s horizontal location within 50 meters for at least 80 percent of 911 calls, and carriers deploying vertical-axis technology must pinpoint the caller’s floor level within three meters for 80 percent of calls.6Federal Communications Commission. Indoor Location Accuracy Timeline and Live Call Data Reporting Accuracy still varies in rural areas, inside large buildings, and on older devices. State your location out loud rather than assuming the system has it right.
Under Kari’s Law, every multi-line phone system installed after February 2020 in places like hotels, office buildings, and college campuses must let you dial 911 directly without pressing 9 or any other prefix first. The system must also notify a designated on-site person, such as a front desk manager, that a 911 call was made.7Federal Communications Commission. Kari’s Law and RAY BAUM’s Act 911 Direct Dialing If you’re in a hotel room or office and aren’t sure whether the phone requires a prefix, try dialing 911 directly first.
Text-to-911
A growing number of 911 call centers accept text messages, though coverage is not yet universal. The service exists primarily for people who are deaf, hard of hearing, have a speech disability, or are in a situation where making a voice call could put them in danger. If you text 911 in an area that doesn’t support it, you should receive a bounce-back message telling you to call instead.8Federal Communications Commission. Text to 911: What You Need to Know You can check whether your local call center supports text-to-911 through the FCC’s public registry.9Federal Communications Commission. PSAP Text-to-911 Readiness and Certification Registry
When texting 911, keep messages short and factual. Include your location, what’s happening, and how many people need help. Skip abbreviations and emojis. A voice call is preferred when you can safely make one, because it lets the dispatcher ask follow-up questions in real time.
Reporting Without Calling Directly
Many departments accept anonymous tips through dedicated phone lines or online portals. Programs like Crime Stoppers let you report information about criminal activity without giving your name. If anonymity matters, use a system built for it. Sending a tip through social media, even as a direct message, is not reliable: departments generally monitor those channels for public relations rather than as crime intake, and there’s no guarantee anyone will see your message promptly.10USAGov. Report a Crime
Online reporting systems work well for incidents that don’t require an officer to come to you: thefts with no suspect information, minor property damage, lost items. You’ll receive a tracking number and eventually an official report number. Keep it. Even for minor incidents, having a report on file creates a record that can matter later.
When a Federal Agency Is the Right Contact
Local police handle the vast majority of crime reports, but some situations call for contacting a federal agency directly, either instead of or in addition to your local department.
- Internet crime: Report to the FBI’s Internet Crime Complaint Center (IC3) and contact your local FBI field office.
- Hate crimes and organized crime: Submit a tip to the FBI online or call 1-800-225-5324.
- Identity theft: File a report with the Federal Trade Commission at IdentityTheft.gov, then also file with your local police. The combined “Identity Theft Report” gives you stronger protections, including the ability to force companies to stop reporting fraudulent accounts on your credit.
- Mail theft and mail fraud: Report to the U.S. Postal Inspection Service online or by calling 1-877-876-2455. For suspicious mail that may contain dangerous materials, call the same number and say “Emergency.”
10USAGov. Report a Crime11United States Postal Inspection Service. Report a Crime
If a crime is actively in progress or someone needs medical attention, call 911 first regardless of which federal agency has jurisdiction. Federal reporting can wait until the immediate danger has passed.
Legal Consequences of Misusing 911
Calling 911 as a prank, filing a false police report, or making a fake emergency report to trigger an armed response (commonly called “swatting”) can bring serious criminal charges. Most states treat knowingly misusing the 911 system as a misdemeanor, with fines that can reach several thousand dollars and potential jail time. Courts can also order you to reimburse the government for the full cost of the emergency response.
Federal stakes are higher. Conveying false information about a bombing, active shooter, or similar large-scale threat is punishable by up to five years in prison. If someone is seriously injured because of the false report, the maximum sentence jumps to 20 years. If someone dies, the person responsible faces up to life in prison.12GovInfo. 18 USC 1038 – False Information and Hoaxes Federal courts have also imposed mandatory reimbursement of all emergency response costs on anyone convicted under this statute. Swatting prosecutions have become more common, with federal sentences of three to four years in cases that didn’t result in physical injury.
None of this applies to good-faith callers. If you genuinely believe an emergency is happening and you call 911, you’re not at legal risk even if you turn out to be mistaken. The laws target intentional misuse, not honest mistakes.
