The History and Purpose of Police 10 Codes

Police codes, including 10-14, were originally developed in 1937 by the Association of Public-Safety Communications Officials (APCO) and are commonly referred to as APCO Ten Signals. These codes were created to ensure fast and efficient communication over radios, especially when audio quality was poor or time was limited.

By using short numeric codes like 10-14, officers can quickly convey important information without the need for long explanations. This system minimizes misunderstanding and improves safety for officers and civilians alike.

Historical Background of Police Radio Codes

The concept of police codes originated in the early 20th century, with APCO introducing Morse code brevity codes in its 1935 bulletin, initially adapted from the U.S. Navy’s communication protocols. Though originally designed for Morse code, these codes later evolved into the voice-radio codes we know today, enabling fast and effective spoken communication.
