The Origin of Alphabet Police Codes

The use of standardized communication codes in law enforcement dates back to 1937 when the Association of Public-Safety Communications Officials (APCO) introduced the APCO Ten Signals—commonly known today as 10-codes (like 10-4 for “acknowledged”). Alongside these numeric codes, police departments also adopted a phonetic alphabet system to ensure that letters and words could be clearly understood, even in noisy or stressful situations.
This system became essential in eliminating confusion caused by similar-sounding letters such as “A” and “H” or “B” and “D” when spoken over the radio. In this system, the letter “A” is represented by the word “Adam”, which is why it’s often referred to as the Adams code.

What Are Police Codes?

These codes are critical for maintaining effective communication, especially in fast-paced emergency scenarios.

You can even listen to police codes like the Adams Code with a police scanner — many of which are accessible online or via mobile apps.
These radio codes, such as 10-4 (Acknowledged), 10-7 (Out of Service), and 10-42 (Ending Tour of Duty), help officers relay information without using lengthy explanations. The use of brevity not only enhances response times but also maintains discretion and professionalism in sensitive situations.

A Legacy of Communication: The History of Police Codes

Police codes have a long and fascinating history. The original system of brevity codes began to take shape between 1937 and 1940, driven by the need for efficient radio communication. In 1974, the Association of Public-Safety Communications Officials-International (APCO) expanded the system, formalizing what is now known as the APCO 10-code system, still widely used by many departments today.
Interestingly, APCO first proposed Morse Code brevity codes as early as June 1935 in The APCO Bulletin, adapting procedures from the U.S. Navy. While initially meant for Morse code communication, the concept was later transitioned to voice radio, becoming the foundation for modern-day police radio codes.
