311 is a special telephone number used in many communities across the United States and Canada to provide access to non-emergency municipal services and information. It serves as a central hub for residents to report problems, ask questions, or make complaints related to city services without tying up emergency lines like 911, which are reserved for urgent emergencies such as fires, crimes in progress, or medical crises

. Typical uses of 311 include reporting issues like graffiti, road damage, noise complaints, dangerous animal sightings, pest problems, malfunctioning traffic lights, trash or debris blocking walkways, broken meters, leaking hydrants, and sewer issues. It also helps citizens find contact information for city agencies and request services such as bulk pickups

. The 311 system was first implemented in Baltimore in 1996 and has since expanded widely, including a major operation in New York City starting in 2003. It is designed to divert routine inquiries from 911, ensuring emergency responders can focus on true emergencies

. Many cities also provide online portals, mobile apps, and social media options to access 311 services, increasing convenience and accessibility

. Besides convenience for citizens, 311 helps local governments save costs by reducing the burden on emergency services and improving resource allocation through data collected from calls and requests. It operates 24/7 and is typically free to use

. In summary, 311 is used for non-emergency city services and information, providing an easy, efficient way for residents to connect with their local government for everyday issues and inquiries
