When to Use the Non-Emergency Line Instead of 911
The rule is simple. If someone is in danger right now, or a crime is happening right now, call 911. Everything else belongs on the non-emergency line. Tying up 911 with a report about a bike stolen last Tuesday can delay the response to someone having a heart attack a few blocks away.
Typical reasons to use the non-emergency number:
- Past crimes with no suspect present, like a vehicle break-in you discovered this morning, overnight vandalism, or a stolen package
- Noise complaints, such as a loud party or a persistent barking dog (O’Fallon, MO regulates noise under Section 215.237 of its municipal code)4City of O’Fallon, MO. O’Fallon MO Code Chapter 215 – Offenses
- Parking violations, like a car blocking your driveway or parked illegally on your street
- Animal control issues, including stray animals, barking complaints, or pet licensing questions
- Suspicious activity that isn’t immediately threatening, such as a vehicle parked in your neighborhood for days or ongoing suspected drug activity
- Information requests, like asking about fingerprinting services or following up on a prior report
If you genuinely can’t tell whether your situation is an emergency, call 911. Dispatchers are trained to triage and will redirect you to the non-emergency line if that’s where the call belongs. That’s safer than the reverse mistake.
What to Have Ready Before You Call
Dispatchers work through non-emergency reports faster when callers have their details organized. Before you dial, gather what you can:
- Exact location: street address, cross streets, business name, or apartment number
- When it happened: date and approximate time, or when you discovered the issue
- Description of anyone involved: clothing, height, build, hair color, direction of travel
- Vehicle details: make, model, color, and license plate number
- A brief, factual description of what happened
- Your own name, phone number, and address so officers can follow up
Writing these down before calling prevents the common problem of forgetting a key detail mid-conversation. If you have photos, security camera footage, or other evidence, tell the dispatcher so an officer knows what to collect. These same details also form the backbone of the written report you may later need for an insurance claim, so getting them right the first time saves work later.
Hold on to any report or incident number the dispatcher gives you. If you lose it, the records clerk has to search by date and name, which slows everything down and sometimes turns up the wrong incident.
