What is the origin of the 10-20 code, and how did it become widely used?
The 10-20 code originated in the 1930s, developed by Charles Hopper, a radio engineer for the Illinois State Police. Hopper created a system of numerical codes to help officers quickly communicate over radio frequencies without using clear language, which could be intercepted by the public or criminals. The codes were initially used by the Illinois State Police but soon spread to other law enforcement agencies across the United States.
The widespread adoption of the 10-20 code can be attributed to its simplicity and effectiveness. The codes were easy to remember and provided a concise way for officers to convey complex information, such as locations, situations, and requests for assistance. As law enforcement agencies began to share and adopt the codes, they became a standardized language, facilitating communication and coordination between different departments and jurisdictions.
What does “10-20” specifically mean, and how is it used in law enforcement communication?
In the context of the 10-20 code, “10-20” is a specific code that means “location.” When an officer requests a “10-20,” they are asking for the location of a person, vehicle, or incident. This code is often used in situations where an officer needs to respond to a call or locate a suspect. For example, an officer might radio dispatch and say, “I need a 10-20 on the suspect’s vehicle,” which would prompt dispatch to provide the vehicle’s location.
The use of “10-20” in law enforcement communication is a prime example of how the code system enables efficient and concise communication. By using a simple numerical code, officers can quickly convey complex information and receive the necessary details to respond to a situation effectively. This code, in particular, has become an integral part of law enforcement culture and is widely recognized, even outside of law enforcement circles.
