In police radio communication, clarity is essential. Background noise, accents, or poor signal quality can easily distort words or letters. To eliminate confusion, law enforcement uses the APCO (Association of Public-Safety Communications Officials) phonetic alphabet, also known as the police alphabet, where each letter is represented by a specific word. In this system:

  • H = Henry

So, when an officer says “Henry” over the radio, they are referring to the letter H. This can be used in license plates, suspect descriptions, or dispatch codes — for example, a vehicle tag might be communicated as “Adam-Boy-Henry-123.”

The History Behind Alphabet Police Codes

The Henry Alphabet Police Codes are part of a broader system initially developed in the 1930s. The original codes, called the APCO Ten Signals, were introduced in 1937 to streamline and clarify communications among officers and dispatchers. These were later adapted into the phonetic alphabet that we know today, including words like Adam (A), Boy (B), Charlie (C), and Henry (H).

These phonetic codes serve a similar purpose to the NATO phonetic alphabet (e.g., Alpha, Bravo, Charlie), but they were specifically tailored for public safety communications in the United States.

Why the “Henry” Code Matters in Police Communication

Using the Henry Alphabet Police Code helps prevent errors during high-stress or high-stakes situations. For example, saying the letter “H” over a crackly radio could easily be mistaken for “A” or “F.” But saying “Henry” makes the intended letter unmistakably clear.

This can be especially important when:

  • Describing suspects or their belongings
  • Spelling out names or addresses
  • Communicating license plate information
  • Coordinating with dispatch

Why Police Codes Matter

Police radio codes are essential tools for ensuring fast, clear, and efficient communication among law enforcement officers, first responders, and emergency personnel. These codes allow officers to relay important information quickly while reducing radio chatter and maintaining confidentiality. From everyday patrols to high-stakes emergencies, police codes like the Henry Code help save time—and lives.

The Henry Police Code, in particular, is just one example of how these short, standardized codes contribute to effective field operations. You can even listen to these codes in real time using a police scanner, where you’ll often hear a wide range of communication such as code 10-4 (Acknowledgment), 10-20 (Location), and 10-7 (Out of Service).

A Brief History of Police Codes

Police codes trace back to the years between 1937 and 1940, when early versions were developed to help emergency personnel communicate faster and more clearly. These codes were later standardized and expanded in 1974 by the Association of Public-Safety Communications Officials-International (APCO). The original brevity codes were inspired by U.S. Navy Morse code procedures and adapted for law enforcement use.

In fact, APCO first proposed Morse code-based brevity codes in the June 1935 issue of The APCO Bulletin, long before voice communication became widespread. These historic developments laid the groundwork for the 10-code system we use today.

Commonly Used Police Codes

Among the most frequently heard police radio codes are:

  • 10-7: Officer out of service
  • 10-42: Ending tour of duty
  • 10-4: Message received
  • 10-20: What’s your location?

These codes are critical in coordinating police activity across various departments and states.
