Understand the History Behind the 30s Police Code and Modern Police Communication

Police codes, including the 30s Police Code, trace back to the late 1930s when the Association of Public-Safety Communications Officials-International (APCO) developed the “Ten Signals” to streamline emergency communication. The original system was inspired by military Morse code standards and later adapted to voice radio use to improve response coordination among officers.

The APCO Ten-Codes, still widely used today, were officially proposed in the June 1935 issue of The APCO Bulletin. Initially, they were rooted in the Navy’s procedure symbols for Morse communications but were transformed to fit the evolving demands of voice-based law enforcement communications. The 30s Police Code is a result of this evolution, fine-tuned for fast, secure, and efficient police response.

From Code 30s to Code 10-42: Everyday Radio Calls That Matter

While the 30s Police Code is specific to homicide by shooting, police officers rely on a wide range of codes daily to report incidents, check in with dispatch, and signal the end of their shifts. For instance, one of the most recognized codes is 10-7, meaning “Out of Service,” followed by 10-42, which marks the end of an officer’s tour of duty. Each code serves a purpose, helping to maintain order, speed, and safety across communication channels.
