Why the 27 Police Code Matters in Police Communication

The use of numeric police codes, including Police Code 27, originated in the late 1930s. Specifically, these codes were introduced between 1937 and 1940 as part of the APCO (Association of Public-Safety Communications Officials) Ten Signals system. In 1974, the system was standardized and expanded to improve clarity and communication efficiency across jurisdictions.

Having a universal code like 27 for “Attempted Crime” ensures that officers, dispatchers, and support teams are all on the same page. It allows police departments to maintain concise and professional communication, especially in high-pressure situations where every second matters.

Understanding Attempted Crime—What Does Police Code 27 Represent?

In legal terms, an attempted crime involves the intention to commit a criminal act and taking substantial steps toward completing it—though the crime itself is never fully executed. When an officer reports a 27 over the radio, it signals that a suspect has tried but failed to complete a crime, and this requires swift investigation or backup.

The Origins of Police Codes—From Morse to Modern Day

The evolution of police codes is deeply rooted in history. In fact, APCO’s first attempt to standardize communication dates back to a 1935 issue of The APCO Bulletin, where Morse code brevity symbols (inspired by U.S. Navy practices) were proposed. Although these early efforts used Morse, they laid the groundwork for the voice-based ten-code system we know today.

Police codes have continued to evolve, but their core purpose remains unchanged: to enable precise and fast communication that saves time, reduces confusion, and helps officers serve the public more effectively.
