Roger That 10-4: The Meaning and History of a Classic Radio Communication Phrase
Radio communication has been an essential tool for military, aviation, and emergency services for decades. Having a clear and concise communication protocol saves lives and prevents confusion during crucial moments. One of the most famous phrases used in this context is “Roger That 10-4.” This phrase has become so ubiquitous that it has crossed over from the military and aviation world into everyday conversation. In this article, we’ll delve into the meaning and history of “Roger That 10-4” and how it became a part of the cultural lexicon.
The Meaning of “Roger That 10-4”
At its core, “Roger That 10-4” is a communication protocol between two parties to confirm that a message has been received and understood. Let’s break it down:
-Roger: This term signifies that the message has been received. It stems from the era when radios were still relatively new, and aviation and military services required a phonetic alphabet to ensure clarity in communication. The phonetic alphabet substitutes each letter with a corresponding word, and “R” represents “Received.” In this context, Roger means that the message has been heard and understood.
-That: This word confirms that the speaker has understood the message and signals that the speaker is about to take action.
-10-4: This phrase means “Message received and understood.” It was derived from the ten-code used by law enforcement and emergency services to communicate quickly and efficiently. The ten-code is a series of numerical codes that replaced the phonetic alphabet to save time and reduce confusion. The ten-code 10-4 specifically means, “I acknowledge.”
Together, “Roger That 10-4” means that the speaker has received and understood the message and is ready to act upon it.
The History of “Roger That 10-4”
The origins of “Roger That 10-4” can be traced back to the early days of radio communication. In 1932, the U.S. Army adopted the phonetic alphabet, including the word “Roger.” The word gained widespread acceptance after it was featured in the 1949 film “Twelve O’Clock High,” a World War II drama about the U.S. Army Air Corps. The film showcased the use of radios and emphasized the importance of having a standardized communication protocol.
The ten-code was developed by the Association of Public-Safety Communications Officials (APCO) in the 1940s to replace the more cumbersome phonetic alphabet. The ten-code allowed for quicker and more efficient communication and reduced the chances of miscommunication. Over time, the ten-code became widely used by law enforcement and emergency services in North America.
The ten-code 10-4 gained popularity through various movies and TV shows, including “Adam-12” and “Hill Street Blues,” both police dramas featuring officers using the ten-code to communicate. Eventually, the phrase crossed over into mainstream culture, and “Roger That 10-4” became a shorthand for “I understand” or “Message received.”
How “Roger That 10-4” is Used Today
Today, “Roger That 10-4” is frequently used in everyday conversation, either to show agreement or as a facetious way of acknowledging that you heard what someone said.

With such widespread use, it’s worth noting that “Roger That 10-4” can be interpreted differently depending on the context. If someone says “Roger That 10-4” to indicate that they understand a message, it could be seen as a formal acknowledgement.
