This efficient communication helps preserve resources while ensuring no time is lost when medical help might be urgently needed.

A Brief History of Police Codes
The origin of police codes dates back to the late 1930s when the Association of Public-Safety Communications Officials-International (APCO) first introduced the APCO Ten Signals in 1937. These signals were designed to increase efficiency in communication between officers and dispatchers, especially during high-pressure situations. The codes were further refined and expanded by APCO in 1974 to accommodate evolving communication needs within the law enforcement community.

How Police Codes Have Evolved
APCO initially proposed Morse code brevity codes in the June 1935 issue of The APCO Bulletin, which were adapted from the U.S. Navy’s Morse code procedures. These codes evolved over time, transitioning from Morse code to voice communication for real-time radio transmissions. This shift allowed for greater flexibility and efficiency in law enforcement operations.

Commonly Used Police Codes
Among the most commonly used police codes are those related to the end of a shift. For instance, when an officer completes their shift, they use the 10-7 code (Out of Service) followed by the 10-42 code (Ending Tour of Duty). These shorthand codes help to quickly communicate an officer’s status without needing lengthy explanations.
