The History Behind Police Codes – From Morse to Modern Communication

The system of police codes was originally developed between 1937 and 1940, with major contributions from the Association of Public-Safety Communications Officials-International (APCO). These communication codes were later expanded and standardized in 1974, greatly improving emergency response effectiveness across jurisdictions.

Interestingly, APCO’s first step toward this system began in 1935 with the proposal of Morse code brevity codes, which were based on U.S. Navy procedure symbols. These early systems weren’t initially intended for voice but laid the foundation for what would evolve into modern police 10-codes.

One of the most emotional uses of police codes occurs during an officer’s final sign-off: the 10-7 code (out of service) followed by the 10-42 code (end of tour of duty), a solemn and respectful way to honor their service.
