History Behind the 11-56 Police Code and the APCO System

The use of police codes began in the late 1930s as part of an effort to standardize communication protocols across police departments in North America. The concept was originally developed between 1937 and 1940 by the Association of Public-Safety Communications Officials-International (APCO). These codes, which included the famous “10-codes,” were created to speed up communication, reduce radio congestion, and improve clarity when transmitting voice messages over radio waves.

Before the adoption of voice communication, APCO initially experimented with Morse code brevity signals in the June 1935 issue of The APCO Bulletin. These were adapted from U.S. Navy procedure symbols and intended for use in telegraph-style messaging. It wasn’t until the 1940s that police departments began using voice-based codes like the 10-series and 11-series, which include codes such as 11-56.

Today, the 11-56 Police Code remains an important tool in an officer’s arsenal. It signals an urgent situation where an officer may be in danger and followed by suspects deemed dangerous. The timely broadcast of such a code can be the difference between life and death, which is why clear radio communication remains a top priority in law enforcement.
