History Behind Police Codes and the 19.03 Signal

Police codes, including 19.03, have a rich history. These shorthand codes were originally introduced as part of the APCO Ten Signals in 1937 to standardize radio communications for police departments nationwide. By 1974, these codes were expanded and formalized further by the Association of Public-Safety Communications Officials-International (APCO), ensuring consistency in communication practices.

But the story doesn’t start there. Back in 1935, APCO published Morse code-based brevity symbols in their monthly bulletin, influenced by the communication procedures of the U.S. Navy. While those early codes were used for Morse transmissions rather than voice, they laid the groundwork for what would eventually become today’s widely recognized police codes—including 19.03.

Everyday Use of Police Codes: 19.03 and Beyond

The 19.03 Police Code isn’t the only one used regularly. Law enforcement relies on dozens of police codes daily, from status updates and location markers to crime-specific signals like 19.03. For example, when an officer finishes their shift, they typically signal “10-7” (Out of Service) followed by “10-42” (End of Tour of Duty), demonstrating the continued relevance of concise radio codes in daily police operations.
