The police code 10-39, used by many law enforcement agencies across the United States, is a standardized shorthand that allows officers to communicate critical information quickly and clearly.

This radio code is most often used in emergency situations where a swift police response is necessary, such as in-progress crimes, accidents with injuries, or active threats to public safety. The use of lights and sirens helps to alert other drivers and pedestrians that a police vehicle is en route to an emergency, clearing the way and ensuring a faster arrival at the scene.

The History Behind Police Codes

Police codes have a long and fascinating history. They were first introduced between 1937 and 1940 to improve radio communications among emergency personnel. In 1974, the Association of Public-Safety Communications Officials-International (APCO) officially expanded and standardized many of these codes to better meet the growing needs of law enforcement.

Interestingly, the concept of brevity codes can be traced back even further. APCO originally proposed Morse code brevity codes in their June 1935 issue of The APCO Bulletin. These codes were adapted from U.S. Navy communication procedures and, while originally designed for Morse code transmission, eventually evolved into the voice-based codes we know today.
