Origin of Police 10-Codes

The use of police codes dates back to 1937 when the Association of Public-Safety Communications Officials (APCO) introduced the APCO Ten Signals, also known as ten-codes. These codes were designed to shorten radio communication and ensure clarity, especially in high-stress situations. Over time, ten-codes became standardized among many law enforcement agencies across the United States.

What is the 10-109 Police Code?

The 10-109 police code is just one of many 10-codes or Ten Signals used daily in law enforcement radio communication. These short numeric codes are designed to convey critical information quickly and clearly, especially in high-stress situations where every second counts.

Why Police Codes Matter

Police communication codes play a crucial role in helping first responders communicate effectively during emergencies. They help reduce confusion, streamline dispatching, and ensure faster response times. Our team at All Police Codes has spent years studying and curating this information to make it accessible to the public.

These codes are used by various emergency services including police officers, firefighters, paramedics, and dispatchers across different states and jurisdictions. While some codes are standardized, others can vary slightly by region – which is why having a reliable guide is essential.

The History Behind the Police 10-Codes

Police 10-codes were first introduced between 1937 and 1940 as a way to standardize radio communication among public safety officials. In 1974, the Association of Public-Safety Communications Officials-International (APCO) expanded the original list to meet the evolving needs of emergency services.

Interestingly, APCO initially proposed brevity codes based on Morse code procedures from the U.S. Navy, as published in a 1935 issue of The APCO Bulletin. These Morse-based signals later evolved into voice-based codes that are still in use today, helping streamline law enforcement communication across the country.

Most Commonly Used Police Codes

One of the most recognized and emotional uses of police codes occurs when an officer retires or passes away. In such cases, the officer or dispatcher may use the 10-7 code (meaning “Out of Service”) followed by 10-42 (signifying “End of Tour of Duty”). These codes serve as a solemn sign-off, honoring the officer’s service and sacrifice.
