History and Purpose of 10-Codes in Law Enforcement

The use of 10-codes, including the 10-0 police code, dates back to 1937, when they were first introduced by the Association of Public-Safety Communications Officials (APCO). These codes, officially known as APCO Ten Signals, were developed to improve radio communication among police officers, especially in situations where time is of the essence.

By shortening standard messages into numerical codes, law enforcement agencies can communicate clearly and efficiently—without misinterpretation—even over poor radio connections or in high-stress situations.

Why the 10-0 Police Code Is Important

The 10-0 code is more than just shorthand—it’s a safety signal. Officers hearing “10-0” on the radio know they need to be on high alert. It may signal that:

• A situation could escalate quickly.
• Backup may be needed.
• There are threats nearby.
• An individual or scene may be dangerous.

In other words, the 10-0 police code signals a need for extreme caution and potentially a strategic approach before proceeding.

The Legacy of Police Codes: A Historical Overview

The use of police codes dates back to the late 1930s. Between 1937 and 1940, the first iterations of what we now know as the 10-code system were developed. In 1974, the Association of Public-Safety Communications Officials-International (APCO) officially expanded the system to support evolving communication needs.

Interestingly, the idea of using concise codes for communication originated even earlier. In June 1935, APCO proposed a series of Morse code brevity codes in The APCO Bulletin. These codes were initially adapted from U.S. Navy procedures and were intended for use in Morse code transmissions rather than voice communication. Over time, they evolved into the standard voice radio codes used today.

Understanding the 10-0 Code and Other Common Police Signals

Among the wide array of police 10-codes, the 10-0 code is a particularly important one. While specific meanings can vary slightly by region, 10-0 generally signifies “Officer Down / Emergency – All Units Respond.” It’s a serious code used in life-threatening situations and requires immediate backup and response.

Other commonly used codes include:

• 10-7 – “Out of Service”
• 10-42 – “Ending Tour of Duty” (often used ceremonially when an officer retires)

You can hear codes like 10-0 in action by tuning in with a police scanner, which allows you to listen to real-time law enforcement communications in your area.
