History of Police Codes: From APCO to the 10-101 Police Code

Police radio codes, also known as “Ten Codes,” were originally developed in 1937 by the Association of Public-Safety Communications Officials (APCO). These codes were designed to allow for short, standardized messages over two-way radios, replacing lengthy verbal explanations with easy-to-understand numeric shorthand.

The “Ten Signals” system, which includes the 10-101 police code, was a revolutionary step forward in public safety communication. It helped law enforcement personnel communicate across different departments and agencies without confusion. Although some regions have adopted plain language alternatives in recent years, many jurisdictions still actively use these 10-codes in day-to-day operations.

How the 10-101 Police Code Is Used in Law Enforcement

After checking a property for suspicious activity
Following a routine security patrol
Completing a welfare check on a citizen
Wrapping up surveillance in a potentially high-risk area

Using the 10-101 police code streamlines the process of reporting and ensures other officers and dispatchers are updated instantly. It allows for quick updates without disclosing too much information publicly, which can be vital for officer safety and operational security.

History of Police Codes: From Morse Code to Modern-Day Communication

Police codes have a fascinating history that dates back to the late 1930s. Between 1937 and 1940, early radio communication codes were developed to streamline communication for emergency personnel. These codes were standardized and further expanded in 1974 by the Association of Public-Safety Communications Officials-International (APCO).

In fact, APCO first proposed the idea of brevity codes for Morse communications in the June 1935 issue of The APCO Bulletin. These early codes were inspired by the communication protocols used by the United States Navy and later adapted for voice radio communication by law enforcement.
