955 Police Code—Detail Under Control

The 955 Police Code stands for “Detail Under Control.” This code is typically used when a situation previously requiring police presence has been resolved or brought under control, signaling that no additional backup or resources are necessary at the moment. When this code is broadcast over the radio, it informs dispatch and nearby units that the scene has been stabilized. If you’re using a police scanner, you might hear 955 being used during the aftermath of a tense situation, such as a traffic stop, crowd control, or a routine detail that no longer requires additional attention.

Why Police Codes Like 955 Matter

Police codes originated in the late 1930s as a way to shorten and standardize communication across police radio channels. The first version of the Ten-Code system—also known as the APCO 10 Signals—was introduced between 1937 and 1940 by the Association of Public-Safety Communications Officials-International (APCO). In 1974, the APCO codes were revised and expanded to cover a broader range of communication scenarios, including specialized codes like 955.

Interestingly, even before these ten-codes came into use, APCO had experimented with Morse Code brevity signals. In 1935, they proposed a system inspired by U.S. Navy procedure symbols, although these early codes were intended for Morse transmissions, not voice. This laid the groundwork for today’s voice-based systems, which evolved into the numerical codes still in use.

A single code like 955 can convey a complete update in just a few digits—saving precious time during emergencies.
