The 459a police code meaning for the police forces is Burglar Alarm.
If you’ve ever listened to police scanners or watched crime dramas, you’ve probably heard officers using numeric codes to communicate quickly and efficiently. One of these codes is the 459a police code. But what does it actually mean? Let’s break it down.
What Is 459a Police Code?
The 459a police code is used by law enforcement to refer specifically to a Burglar Alarm call. When officers hear or use the code “459a,” it signals that a burglar alarm has been triggered, and they are being dispatched to investigate a possible break-in or burglary in progress.
This code is an extension of the standard “459” police code, which refers to burglary in general. The added “a” in 459a distinguishes the nature of the incident, specifying that it involves a burglar alarm activation rather than a confirmed or ongoing burglary.
Why Do Police Use the 459a Police Code?
Police codes like 459a are part of a system known as ten-codes or penal codes, which help streamline communication between officers, dispatchers, and emergency personnel. Rather than saying “We have a triggered burglar alarm at a commercial building,” officers simply use 459a to communicate the same message.
Here are some key benefits of using codes like 459a in police communication:
- Speed: Time is critical in emergency situations, and short codes allow officers to respond faster.
- Clarity: Police codes reduce the chances of miscommunication, especially over radios where signals can cut out.
- Brevity: Using a concise code like 459a avoids long explanations, which is useful during high-pressure moments.
- Standardization: Codes provide a common language for officers across jurisdictions, ensuring better coordination.

Explore All U.S. Police Codes—Past and Present
Our website features a complete catalog of all police codes used in the USA, including those developed historically and those still in daily use. Police codes were originally developed between 1937 and 1940, with a significant update and expansion occurring in 1974, led by the Association of Public-Safety Communications Officials-International (APCO). In fact, APCO’s contributions helped standardize communication systems across thousands of law enforcement agencies in the United States.
The origins of these codes can be traced back even further to 1935, when APCO first proposed Morse code brevity signals. These were modeled after U.S. Navy communication protocols—though designed for Morse, not voice communication—and laid the foundation for the efficient radio codes we know today.
