What Is a Code 10 Police Code? Code 10 Police Code

The Code 10 police code meaning for the police forces is Bomb Threat / Patrol Your District And Report Extent Of Damage.

The Code 10 Police Code is a critical signal used in law enforcement communication. When officers refer to Code 10, they are responding to one of two urgent situations: a Bomb Threat or an instruction to Patrol Your District and Report the Extent of Damage. In both cases, this code is issued to alert officers of a potentially dangerous scenario requiring immediate attention, evaluation, and action. The meaning of Code 10 may vary slightly depending on the jurisdiction, but it generally signals a high-alert situation where rapid communication and coordinated response are essential.

Police departments across the United States rely on standard and localized radio codes like Code 10 to streamline field communication. Instead of explaining a full incident over the radio, officers can say “Code 10,” and their colleagues instantly know the urgency and expected actions—whether it’s locating a possible explosive device or assessing destruction within a patrol zone after a critical event such as a riot, fire, or natural disaster.

Code 10 Police Code: Bomb Threat and Damage Assessment Situations

In its most common usage, the Code 10 police code signals a bomb threat, alerting officers to secure the area, evacuate civilians if necessary, and call in the bomb squad. Alternatively, it can be used after a major incident when officers are ordered to patrol their assigned district and report on any visible damage, helping dispatchers and emergency management coordinate resources efficiently.

The use of police radio codes like Code 10 ensures that critical information is transmitted quickly, clearly, and without confusion. In high-stakes emergencies, there’s no room for miscommunication. Using short numeric codes helps officers maintain focus, especially in chaotic environments where every second counts.

Why Do Police Use Codes Like Code 10?

The tradition of police radio codes dates back to the 1930s, when the APCO Ten Signals were first introduced by the Association of Public-Safety Communications Officials-International (APCO). Over the decades, police departments have adopted and customized these codes to enhance operational efficiency. A code like Code 10 allows officers to stay discreet, precise, and professional in high-pressure situations.

These codes are part of a universal language among law enforcement professionals. Whether an officer is responding to a Code 10 Bomb Threat or canvassing an area to report damage, the brevity and clarity of the code improves response time and overall safety.

History of Police Codes – From Morse Code to Modern Signals

Police codes originated between 1937 and 1940, created and refined by the Association of Public-Safety Communications Officials-International (APCO). These became known as the APCO Ten-Codes and were developed to enhance communication clarity across radio systems.

The concept actually dates back to June 1935, when APCO first proposed using Morse code brevity signals inspired by U.S. Navy procedures. While those early codes were for Morse communication, they eventually evolved into the voice-based numeric system still in use today, including Code 10 and other “10-codes.”

Examples of Commonly Used Police Ten-Codes

While Code 10 is crucial for bomb threats and situational assessment, it’s just one of many Ten-Codes that officers rely on daily. Here are a few other notable examples:

10-7 – Officer out of service
10-42 – Officer ending tour of duty
10-20 – Request for location
10-4 – Acknowledgement or affirmation (perhaps the most famous one)

These codes are often heard during police radio transmissions and provide a quick, standardized way for officers to stay connected without confusion.
