What Is a 417 Police Code? 417 Police Code

The 417 police code meaning for the police forces is Person With A Gun or Brandishing A Firearm.

The 417 police code is a critical part of police radio communication, particularly in California and other U.S. states that use numeric police codes. The 417 police code specifically refers to “Person with a Gun” or “Brandishing a Firearm.” This code is used when an officer encounters or is alerted to an individual displaying or carrying a firearm in a threatening or suspicious manner.

Understanding the 417 Police Code Meaning

In law enforcement terminology, the 417 police code is issued during potentially dangerous encounters involving firearms. When a dispatcher broadcasts a 417 code, it immediately notifies officers of a serious and potentially life-threatening situation. This allows police units to respond with appropriate caution and urgency.

The phrase “Person with a Gun” under code 417 can involve:

A suspect openly carrying or displaying a firearm
Someone threatening others with a gun
Brandishing a weapon during an altercation

Law enforcement takes all 417 police code calls extremely seriously, as these incidents pose a high risk to officers and civilians alike.

Origins of the 417 Police Code

The use of police codes, including the 417 code, originated in the 1930s with the APCO Ten Signals, developed by the Association of Public-Safety Communications Officials (APCO) in 1937. These signals were designed to streamline radio communication and reduce miscommunication between officers and dispatchers.

Over time, each jurisdiction adapted these ten-codes and developed their own numeric codes, like the California Penal Code 417, which directly relates to the act of brandishing a firearm in a threatening way.

Legal Definition Under California Penal Code 417

In addition to being a radio communication code, California Penal Code 417 outlines the criminal offense of brandishing a weapon or firearm. According to the law:

“Every person who, except in self-defense, in the presence of another person, draws or exhibits any deadly weapon in a rude, angry, or threatening manner… is guilty of brandishing a weapon.”

A violation of Penal Code 417 can result in serious legal consequences, including jail time, especially if committed in sensitive areas like schools or in front of law enforcement officers.

History of Police Codes – A Legacy of Efficiency

The concept of using brevity codes in emergency services began as far back as 1935, when the Association of Public-Safety Communications Officials-International (APCO) first proposed the use of Morse code abbreviations. These early codes were influenced by the U.S. Navy’s procedural signals. By 1937–1940, voice-based 10-codes started being developed and later expanded in 1974 to meet the growing needs of emergency communications.

Over time, these 10-codes, 11-codes, and signal codes became standardized in many regions, though some local departments still use custom versions. Even today, many agencies continue to rely on these codes, though some have begun transitioning to plain language for inter-agency clarity.
