The History and Evolution of Police Radio Codes

The concept of police codes dates back to the late 1930s, when the Association of Public-Safety Communications Officials-International (APCO) first introduced them. Originally designed for Morse code transmissions in 1935, these brevity codes were later adapted for voice communication, and the 10-code system as we know it today was born.

In 1974, APCO expanded the list of codes, and since then, they’ve become a crucial part of emergency communication protocols used by police, fire departments, EMS, and other first responders.

Among the most commonly used codes:

10-7: Officer out of service
10-42: Officer ending their tour of duty

These symbolic codes are not only functional—they’ve also become part of the culture and traditions within police departments nationwide.
