What does 10 7 Mean in Police Code?
10 7 in Police Code meaning for the police force is Out of Service (10 7 mean in police lingo).

Police departments across the United States and other jurisdictions often rely on ten-codes (also known as 10-codes) as part of a standardized set of radio communications used for quick and efficient interaction between officers and dispatchers. While the meanings of certain codes may vary slightly depending on the department or state, 10-7 almost universally means “Out of Service.”
Whether you’re a civilian researching police terminology, a journalism student studying emergency communications, or a future police recruit preparing for academy training, understanding what 10-7 means in police code is an essential part of learning how officers communicate on the job.

The term 10-7 in Police Code is one of the many standardized police radio codes used by law enforcement officers, dispatchers, and emergency personnel across the United States and internationally. These ten-codes, including 10-7, play a vital role in maintaining clear and concise communication in high-stress environments. Specifically, 10-7 means “Out of Service,” indicating that an officer is no longer available for duty—whether due to the end of a shift, a break, or a temporary pause in service.
You might hear 10-7 in police code being used during live police scanner transmissions, or while watching popular law enforcement-related television shows and documentaries. It’s a common part of real-time communication between patrol officers and central dispatch, ensuring clarity when units go temporarily offline. These codes have become so embedded in pop culture that many civilians now recognize the more widely used ones like 10-4 (Acknowledged) and 10-7 (Out of Service).
When spoken over the radio, “10-7” is usually enunciated clearly, digit by digit, such as “one-zero-seven,” to ensure that the message is understood without any ambiguity. This is especially important in noisy, chaotic, or high-pressure situations where miscommunication could result in operational delays or safety risks. Dispatchers and police officers are trained to pronounce these codes with precision, particularly during radio transmissions, to prevent any confusion or misinterpretation.
The use of ten-codes like 10-7 in police code dates back to the late 1930s, when law enforcement agencies sought a more efficient method of communication that would save time and reduce the length of messages sent via two-way radio. Between 1937 and 1940, the first versions of these police ten-codes were developed. In 1974, the Association of Public-Safety Communications Officials-International (APCO) expanded and standardized these codes to create a more uniform communication system for public safety agencies across jurisdictions.
This standardization helped reduce confusion among departments and made it easier for different law enforcement agencies to communicate with each other, especially in joint operations or emergencies. 10-7, along with other ten-codes, became part of this shared radio language that continues to be used today.
Police officers regularly rely on radio communication as a core part of their daily operations, especially when coordinating with dispatchers—the personnel responsible for directing officers based on incoming calls, emergencies, or reported incidents. One of the most important elements of this communication system is the use of ten-codes, such as 10-7 in police code, which means “Out of Service” in police lingo. When an officer reports “10-7,” it indicates they are temporarily unavailable for duty—whether ending a shift, taking a break, or stepping away from active service. These codes ensure that both dispatch and fellow officers are aware of the officer’s status, contributing to efficient resource management and public safety.
The structured language of police radio codes helps establish clarity and precision, even in chaotic or high-pressure environments. When officers communicate with dispatch, they use a system of brief but standardized codes designed to save time, reduce errors, and prevent misunderstandings. For example, 10-7 in police terminology is universally recognized in most law enforcement agencies as “Out of Service,” and it is typically spoken digit by digit (e.g., “ten-seven”) to ensure accurate transmission over radio waves.
Beyond communication with dispatch, these codes—especially 10-7 and similar ten-signals—play a key role in communication across the entire law enforcement network. Officers use these codes to quickly and discreetly exchange status updates with other patrol units, detectives, correctional facilities, and local jails, streamlining coordination across departments. A simple code like 10-7 can be broadcast to let everyone in the area know an officer is unavailable, without the need for lengthy verbal explanations.
The use of police codes such as 10-7 enhances the professionalism and effectiveness of law enforcement communications. It allows for seamless multi-agency coordination during joint operations, traffic enforcement, criminal investigations, and emergency response. Without this standardized language, relaying crucial information between officers, dispatchers, and correctional personnel would be slower and prone to misinterpretation, which could put lives at risk.
In addition to improving communication, the consistent use of police codes also supports operational safety, situational awareness, and accountability. By clearly marking when officers are active, on duty, or out of service, departments can better manage manpower, track officer movements, and ensure timely back-up when necessary.
