History of the I/S Police Code and Police Signals in General

The origins of police codes in the United States can be traced back to the 1930s. Between 1937 and 1940, the Association of Public-Safety Communications Officials-International (APCO) developed the APCO Ten-Codes, designed to bring brevity and clarity to law enforcement communications. The I/S Police Code, while not a ten-code itself, follows the same principle of abbreviation-based clarity.

APCO’s early efforts were inspired by Morse code signals used by the U.S. Navy. In fact, their June 1935 bulletin first proposed Morse brevity codes, and over time, these adapted to voice transmission. By 1974, the APCO code system had become widely recognized across local, state, and federal law enforcement agencies.

Real-Life Use of the I/S Police Code

“Multiple units at the I/S of Oak and Pine, requesting traffic control”

As shown in these examples, I/S Police Code is commonly used in relation to incidents happening at street junctions, intersections, or busy crossroads.
