The 10-5 in Police Code is one of many radio communication signals used by law enforcement officers across the country and around the world. It is a standardized code meaning “Relay Message to [Person],” and plays an essential role in helping officers and dispatchers communicate clearly and efficiently, especially in situations where timing and clarity are critical. Whether it’s relaying important updates to a fellow officer or passing on information to another agency, the 10-5 code helps reduce confusion and ensures the message reaches the correct recipient without delay.
You might encounter 10-5 in Police Code while listening to a police scanner, following live radio traffic from emergency services, or watching real-world crime documentaries and police shows on television.

This ensures the message is transmitted clearly over sometimes noisy or low-quality radio systems and helps prevent misinterpretation, especially in high-stress environments.
The use of 10-5 and similar codes can be traced back to the late 1930s. Between 1937 and 1940, these codes were first developed as a practical solution to the technological limitations of early two-way radios. They allowed officers to speak in short, standardized bursts that were easy to understand, saved time, and reduced congestion on the radio channels. Then in 1974, the system was significantly expanded and formalized by the Association of Public-Safety Communications Officials-International (APCO), creating a national standard that allowed public safety agencies to coordinate more effectively across jurisdictional boundaries.
Today, 10-5 in Police Code remains a vital tool in law enforcement communication, forming part of a broader network of ten-codes and radio signals that ensure smooth, secure, and consistent message traffic between officers, dispatchers, and emergency services.
