What Is a 10-12 Police Code? 10-12 Police Code

The 10-12 police code meaning for the police forces is Standby / Visitors Present.

The 10-12 police code is a commonly used term in law enforcement communication that signifies “Standby” or “Visitors Present.” When officers use the 10-12 code over the radio, it typically indicates that someone who is not a member of law enforcement—such as a civilian, a suspect, or an unauthorized individual—is nearby, and that officers should be cautious about what they say. This code helps ensure that sensitive information isn’t accidentally shared in the presence of outsiders.

The History and Purpose of Police 10-Codes

To fully understand what the 10-12 police code means, it’s important to look at the origin of these codes. Police ten-codes, also known as 10-codes, were developed in 1937 by the Association of Public-Safety Communications Officials (APCO). The purpose was to create a standardized, efficient method of communication for law enforcement officers over radio channels. These codes allow officers to communicate quickly and clearly, reducing the chance of misinterpretation during high-stress situations.

The 10-code system helps officers convey complex information using short, numeric phrases. For instance, instead of saying “I have a civilian present, be cautious,” an officer can simply say “10-12.”

Detailed Meaning of the 10-12 Police Code

The primary definition of the 10-12 police code is:

Standby / Visitors Present

In practice, the code warns fellow officers that their conversation might be overheard by individuals who should not have access to police communications. This can include:

Media personnel
Unauthorized personnel

By using 10-12, officers signal that discretion is advised.

When Do Police Officers Use the 10-12 Code?

Officers may use the 10-12 code in a variety of scenarios, such as:

When a suspect is being transported and may overhear radio communication
During a press interaction where confidential information shouldn’t be discussed
In the presence of family members of a victim or suspect
While conducting interviews with civilians nearby

Using the 10-12 police code maintains the professionalism and integrity of communication, helping officers avoid disclosing sensitive information in front of unintended audiences.

A Brief History of Police Codes

The first police codes were introduced between 1937 and 1940, developed to streamline voice communication in an era dominated by Morse code. In 1974, the Association of Public-Safety Communications Officials-International (APCO) expanded the system, creating a standardized set of codes still in use today.

Interestingly, APCO had initially proposed brevity codes in 1935, which were adapted from U.S. Navy signal procedures. These early forms laid the foundation for the voice-based police radio codes used across the country.

Among the most symbolic police codes used today is the 10-42 code, often broadcast when an officer ends their tour of duty – sometimes marking a somber farewell after a long and honorable career. Combined with the 10-7 code (out of service), these calls have become a meaningful part of police tradition.
