The Code 100 police code meaning for the police forces is In Position To Intercept Suspect.

If you’ve ever asked yourself, “What is Code 100 Police Code?” — you’re not alone. The Code 100 Police Code is a key signal used by law enforcement agencies, and it holds a very specific and tactical meaning: In Position to Intercept Suspect.

When officers are issued a Code 100, it means that police units are strategically positioned to intercept a suspect who may be fleeing a scene or is otherwise under surveillance.

Understanding police radio codes like Code 100 is essential for those studying law enforcement procedures, listening to scanner traffic, or simply trying to decode police lingo. These codes allow for faster, clearer, and more secure communication between officers during critical moments — especially in pursuit or apprehension scenarios.

Where Did Code 100 Come From? A Brief History of Police Codes

The Code 100 Police Code is part of a broader system of radio communication signals originally introduced in the late 1930s. Known as the APCO Ten-Codes, these shorthand codes were first standardized between 1937 and 1940 by the Association of Public-Safety Communications Officials-International (APCO). The purpose? To streamline radio traffic and improve efficiency during emergency responses.

Over time, various jurisdictions adapted and added codes tailored to local needs — Code 100 being one of them. While not universally used across every state or department, Code 100 has become a widely understood signal in many areas, especially during coordinated intercept operations.

What Does ‘In Position to Intercept Suspect’ Mean?

The phrase “In Position to Intercept Suspect” is operational language for officers who have been assigned to stop or block a suspect from escaping. This can include creating a perimeter, taking a hidden position, or setting up a roadblock. Essentially, if an officer reports “Code 100” over the radio, it means they’re stationed and ready to detain the target once contact is made.

A Brief History of Police Codes in the U.S.

Police codes have been part of law enforcement since the late 1930s. The first standardized system was developed between 1937 and 1940 by the Association of Public-Safety Communications Officials-International (APCO). The goal was to create efficient communication protocols for public safety officers across the nation. The system was expanded in 1974 to accommodate new policing needs and technologies.

Interestingly, APCO’s earliest proposal appeared in The APCO Bulletin in June 1935, where they introduced Morse code brevity signals inspired by U.S. Navy communication procedures. Though initially used for Morse transmissions, the concept evolved into the voice-based radio codes we recognize today.
