Baltimore, MD
Baltimore was the first city in the nation to begin using 3-1-1 as a police only non-emergency number. It was initially designed to offload non-emergency calls from the 9-1-1 system to reduce delays in answering times. Within 2 months, 42% of the calls from 9-1-1 were effectively transferred onto the 3-1-1 system. Baltimore is currently changing the 3-1-1 police-only system into a total citywide one number system.
