History of Police Codes—From Morse to Modern Radio

The origins of police radio codes trace back to the late 1930s. The Association of Public-Safety Communications Officials-International (APCO) first proposed standardized brevity codes in 1935. Initially inspired by Morse code signals used by the U.S. Navy, these codes were designed to save time and reduce miscommunication during high-pressure situations.

By 1974, APCO expanded and formalized the system, creating the set of 10-codes still widely in use today. While some agencies have moved toward plain-language communication, these codes remain a vital part of law enforcement history and current practice.
