History of Police Codes: From Morse to Modern

The history of police codes is as fascinating as it is functional. Police radio codes were initially developed between 1937 and 1940 and later standardized and expanded in 1974 by the Association of Public-Safety Communications Officials-International (APCO). APCO’s goal was to streamline communication and minimize errors under pressure, a mission that lives on today through codes like 15.01.

Interestingly, APCO began exploring communication codes as early as 1935. In the June issue of The APCO Bulletin, they published Morse Code brevity signals adapted from U.S. Navy procedures. While those were designed for Morse-based transmissions, they laid the groundwork for today’s voice-based police radio codes, including Police Code 15.01.

Closing Code Calls

One of the most common codes in use is the 10-7 signal, indicating an officer is “out of service.” Officers retiring for the day may also use the 10-42 code, signifying the end of their shift. While codes like 15.01 communicate criminal activity, others play a role in officer status updates and dispatcher coordination.
