The History of Police Radio Codes

Police radio codes have a rich history dating back to the late 1930s. The original set of brevity codes was developed between 1937 and 1940, designed to streamline communication between emergency service personnel. In 1974, the Association of Public-Safety Communications Officials-International (APCO) expanded on these codes, creating what we now recognize as the APCO Ten Codes—a standard still widely used in many regions today.

Interestingly, the concept of using brief codes in communication originated even earlier. In June 1935, APCO first introduced Morse code brevity codes in their official publication, The APCO Bulletin. These were inspired by U.S. Navy communication systems and were initially intended for Morse code use, not voice transmission. Over time, they evolved into the spoken radio codes used by modern law enforcement.

Commonly Used Police Codes – Including 10-7 and 10-42

While there are dozens of police codes used every day, some are more frequently heard than others. One of the most emotional and symbolic moments in an officer’s career is when they use the 10-7 code (indicating “Out of Service”) followed by the 10-42 code (meaning “End of Tour of Duty”). These codes are often used during retirement ceremonies or in memory of fallen officers, showing the deeper significance that these codes can carry beyond routine communication.
