History of Police Codes – Where It All Began

The concept of police codes dates back to the late 1930s. Between 1937 and 1940, the Association of Public-Safety Communications Officials-International (APCO) introduced the Ten-Code system, which dramatically improved radio communication across police departments. By 1974, these codes were standardized and expanded to accommodate growing demands.

Interestingly, APCO’s earliest idea for brevity codes appeared in the June 1935 issue of The APCO Bulletin, borrowing structure from U.S. Navy communication methods—though originally designed for Morse code, not voice transmission. Over time, these evolved into the numeric police codes widely recognized today.

Common Code Usage Example in Police Dispatching

One of the most frequently used police codes comes at the end of a shift. When an officer completes their tour of duty, they may call in a 10-7 code (signaling “Out of Service”) followed by 10-42 (meaning “End of Watch” or “End of Tour of Duty”). These brief numeric signals speak volumes in the world of police communication.
