The History and Purpose of Police Ten-Codes like 10-93

To fully grasp the importance of the 10-93 police code, it’s helpful to know where it came from. Police ten-codes, including 10-93, were first developed in the late 1930s by the Association of Public-Safety Communications Officials-International (APCO). These codes were designed to simplify police radio transmissions and reduce the chances of miscommunication during emergency responses.

Since their introduction, ten-codes like 10-93 have become a critical part of police radio language used across the United States. Over time, some departments have created their own variations, but many still use the original APCO code system, making it valuable for anyone following police activity via scanners or interested in public safety communication.

Why Police Codes Like 10-93 Matter

Police codes, also known as Ten Codes, were originally introduced between 1937 and 1940 by the Association of Public-Safety Communications Officials-International (APCO).

The use of codes such as 10-93 provides critical benefits:

It shortens radio transmissions.
It avoids miscommunication.

Police Code History: From Morse to Modern Radio

The roots of police codes run deep. Back in June 1935, APCO proposed the use of Morse code brevity signals, inspired by U.S. Navy procedure symbols. While originally designed for Morse code—not voice—this framework laid the groundwork for what would become today’s Ten Code system. These concise codes eventually evolved into standardized signals that law enforcement agencies continue to use across the U.S.

For example:

10-7 means “Out of Service”
10-42 signals an officer’s “End of Tour of Duty” (commonly used in officer memorials)

These codes are more than shorthand—they represent tradition, service, and efficient law enforcement.
