What Is a 10-24 Police Code? 10-24 Police Code

The 10-24 police code meaning for the police forces is Emergency Backup or Emergency At Station.

If you’ve ever listened to a police scanner or watched a crime drama, you may have heard the term 10-24 police code and wondered what it means. So, what is 10-24 police code? Simply put, the 10-24 police code is a standardized radio communication signal used by law enforcement officers to indicate “Emergency Backup Needed” or “Emergency at Station.” This code is a crucial part of the police ten-code system, which helps officers relay important messages quickly and clearly, especially in high-stress or dangerous situations.

What Does the 10-24 Police Code Mean?

The 10-24 code is used when an officer is in distress and requires immediate assistance from fellow officers. It could mean an officer is facing a threat on the scene and needs backup urgently, or that there’s an emergency at a police station itself. In either case, time is critical, and using the 10-24 police code ensures a rapid, coordinated response.

When this code is transmitted over the radio, all nearby units understand that another officer is in danger and respond accordingly. The brevity and clarity of the code eliminate confusion and save valuable time during emergencies.

Origin of Police 10-Codes: A Brief History

The use of ten-codes in law enforcement dates back to 1937, when the Association of Public-Safety Communications Officials (APCO) introduced the APCO Ten Signals. These codes were developed to create a more efficient way for officers to communicate over radios, especially when dealing with poor signal quality or limited bandwidth.

Instead of long explanations, officers could use short numeric codes like 10-24 to convey complex messages in just a few words. This system helped streamline communication and remains in use today, although some departments have shifted toward plain-language communication to avoid confusion between agencies.

Why the 10-24 Police Code Still Matters Today

Despite advancements in communication technology, the 10-24 police code and other ten-codes remain vital tools for police departments across the United States. In emergency situations where seconds count, these codes provide a fast, unambiguous way to call for help or coordinate action.

Officers are trained to understand and use ten-codes like 10-24 instinctively, ensuring that everyone stays informed and prepared to act. Whether it’s a life-threatening encounter or a sudden emergency at the station, the 10-24 code alerts all available units to spring into action immediately.

Why Police Codes Matter

Police codes—also known as ten-codes or radio signals—were originally developed between 1937 and 1940 to streamline radio communication among law enforcement agencies. The need for speed, clarity, and brevity led to the adoption of this standardized system. In 1974, the Association of Public-Safety Communications Officials-International (APCO) expanded the system to better meet the growing demands of modern law enforcement communication.

The idea of using code numbers originated even earlier. In the June 1935 issue of The APCO Bulletin, APCO proposed Morse code brevity signals inspired by U.S. Navy procedure symbols. While initially designed for Morse code transmissions, these procedures laid the foundation for today’s voice-based ten-code system.

Commonly Used Police Codes

One of the most commonly recognized codes is 10-7, which means “Out of Service.” Officers use it when they’re ending their shift or leaving their patrol area. Another meaningful and ceremonial code is 10-42, often used to mark the end of an officer’s tour of duty, especially during retirement or memorial tributes.

These codes are more than just numbers—they represent a legacy of police tradition, discipline, and operational efficiency. Understanding them can provide valuable insight into the world of public safety and emergency response.
