The Origins and Evolution of Police Codes in the U.S.

Police codes were first developed between 1937 and 1940 by the Association of Public-Safety Communications Officials-International (APCO). These codes, known as the Ten Signals, were designed to make communication more efficient for emergency forces, including police, EMS, and fire departments.

The APCO system was officially expanded in 1974 to support growing communication needs in public safety. Even before that, in 1935, APCO had suggested Morse code brevity codes derived from U.S. Navy procedure symbols. Though originally intended for Morse communication, these ideas laid the groundwork for the voice-based police radio codes used today.
