The History of Police Codes in the U.S.

Police codes—such as 11-65—originated between 1937 and 1940, when the Association of Public-Safety Communications Officials-International (APCO) began developing a set of ten signals, later known as Ten-Codes. These codes became the backbone of police communication. In 1974, APCO revised and expanded the codes to meet modern communication needs and improve nationwide consistency.

Before that, APCO experimented with Morse code signals. In fact, the June 1935 issue of The APCO Bulletin featured their initial brevity codes, derived from U.S. Navy procedures. Although those early codes were designed for Morse transmissions, the idea paved the way for voice-based systems that remain in use today.
