These codes were designed to streamline communication among police officers and emergency responders, especially over radios where time and clarity are critical.

They vary slightly between departments, but many share the same core codes for major offenses and procedures.

History of Police Radio Codes

Police radio codes were originally developed between 1937 and 1940 as a way to streamline radio communications for law enforcement. These codes were later standardized and expanded in 1974 by the Association of Public-Safety Communications Officials-International (APCO), which introduced what is commonly known today as the Ten-Code System.

Interestingly, APCO’s roots in communication go even further back. In June 1935, APCO proposed Morse code brevity signals in The APCO Bulletin, drawing inspiration from U.S. Navy communication protocols. While initially intended for Morse code, these concepts paved the way for the voice-based radio codes used in police departments today.

Commonly Used Police Codes – Beyond 966

While the 966 police code is important, many other codes are essential for everyday law enforcement operations. For instance, one of the most emotionally significant codes in law enforcement is:

10-7 – Out of Service
10-42 – End of Tour of Duty (used when an officer signs off for the last time, often during retirement or in memoriam)

These codes aren’t just functional – they represent moments of honor, duty, and transition.
