The Communications Section operates 24/7, 365 days of the year, answering, processing and transferring all police, 9-1-1 and animal control calls within the city limits of O’Fallon, and communicating with officers on duty to assist with calls. They also enter and process warrants, other agency warrant requests and carry out other clerical duties.

A minimum of two dispatchers work at all times, one in charge of radio communications with police officers and the other answering 9-1-1 and administrative calls.

When should I call 9-1-1?

Residents are strongly urged to use 9-1-1 for human life-threatening situations only. The Police Department has a limited number of 9-1-1 lines and will respond to all calls, even disconnected calls, returned calls that only get a busy signal, accidental calls or a caller deciding police service is not necessary. If an accidental call has been made, please stay on the line until you speak with a dispatcher.

Please refrain from making any other kind of call to 9-1-1 so that citizens with real emergencies can get the help they need quickly.

There is no 9-1-1 system for cell phones, so those calling from a cell phone should be ready to give a location and a call-back number. Also be prepared to have your call transferred due to cell phone towers lacking GPS capabilities.

Calls cannot be transferred to any other emergency service outside of the St. Charles County area except for the Missouri State Highway Patrol. Callers using phone service through an internet provider should be sure the correct address is used.

Vehicle Lock-outs

The Police Department does not respond to unlock unoccupied vehicles due to safety and liability issues; however, residents are urged to call 9-1-1 if a child is locked in a vehicle.
