In an emergency or non-emergency, it's important to know who to call for assistance. While it may seem clear to call 9-1-1 for emergencies, some issues, such as when a situation does not pose an immediate threat but may require police assistance, can be directed to the City of Chicago's non-emergency 3-1-1 City Services center. To report possible terrorism-related suspicious activity in Chicago or Cook County, the public is urged to call 1-855-RPRT-2-S4 (855-777-8274).
