187 Police Code

187 Police Code means Homicide (Murder) and additional police codes and cop codes information. 187 Police Code is part of the emergency codes that are used for fast communication and reducing miscommunication, between the emergency crew.

The 187 Police Code is one of the most widely recognized law enforcement codes in the United States. The meaning of the 187 Police Code is Homicide, which refers directly to murder. When police officers, dispatchers, and emergency responders communicate using the 187 code, they are referring to a situation where a killing has occurred or where a murder investigation is taking place. Because of its association with homicide, the 187 code has also become known outside of police work, appearing in media, television, and even music as a shorthand term for murder.

The 187 Police Code is not just a random number. It is part of the California Penal Code, which formally designates section 187 as the law defining murder. Over time, police departments and emergency crews across the country began using “187” as an emergency communication code. This shorthand allows police officers to quickly and clearly communicate with dispatchers and other units about a homicide case without confusion. By using numeric codes such as 187 Police Code, law enforcement can reduce the risk of miscommunication during fast-moving and high-pressure situations.

Just like other police codes and emergency codes, the 187 Police Code plays an important role in maintaining clear communication between emergency crews, including police officers, firefighters, paramedics, and health teams. Emergency codes are designed to simplify complex messages into short, universally understood terms. In this case, when the code “187” is broadcast, everyone involved immediately understands the severity of the incident and can respond accordingly.

Understanding the 187 Police Code meaning helps the public become more familiar with how law enforcement communicates. While most people hear “187” in crime shows, rap lyrics, or true crime documentaries, it is important to know that this is a serious code used in real-life law enforcement operations. It signals one of the most critical emergencies—homicide—and ensures that all responders act with urgency and precision.

In addition to the 187 Police Code, there are many other cop codes and ten-codes that law enforcement uses every day. Each of these codes, whether it’s 211 for armed robbery, 10-4 for acknowledgment, or 5150 for a mentally disturbed person, plays a vital role in reducing radio traffic confusion and making sure that critical information is passed on quickly and accurately.

187 Police Code & Police Codes History

When were police codes introduced first time?

The 187 Police Code, which stands for homicide or murder, is one of the most recognized emergency codes in law enforcement. To understand how the 187 Police Code became a part of everyday police communication, it is important to look at the broader history of police codes and how they were first developed. Police codes were created to make communication faster, clearer, and more efficient, especially when law enforcement officers needed to respond to emergencies in real time.

The very first set of police codes was introduced in 1937, when law enforcement agencies began experimenting with short, numeric signals that could be transmitted quickly over radio systems. These early codes were tested and refined over a period of three years. The goal was to reduce long radio transmissions, cut through background noise, and eliminate misunderstandings between police officers and dispatchers. By replacing long descriptive sentences with numbers, like “187” for homicide, officers could communicate instantly and without confusion.

It took decades, however, for these codes to become widely recognized and standardized. In 1974—thirty-seven years after their first introduction—the system of police codes and emergency codes was formally expanded and adopted by the Association of Public-Safety Communications Officials International (APCO). This marked a turning point in the history of emergency communication, as APCO’s standardization allowed officers, dispatchers, firefighters, paramedics, and health teams across different states and departments to use the same codes consistently. With this uniform approach, emergency response became more reliable, especially in high-stress, multi-agency situations.

The adoption of police codes, including the 187 Police Code, created a universal language for law enforcement. Instead of long sentences that could get lost in radio static or distorted under pressure, short numeric signals allowed for fast and effective coordination. This system significantly reduced confusion, improved safety for officers in the field, and ensured quicker responses for the public. Today, the legacy of the 1937 introduction of police codes and the 1974 APCO expansion continues to shape how emergency services operate, with the 187 code remaining one of the most well-known examples of how these codes are used in practice.

Emergency codes are a specialized system of communication used by law enforcement, firefighters, paramedics, and hospital staff to transmit critical information quickly and without confusion.
