The 10 Codes of (CB Continued)

In a previous article, we went over the “10” codes that are commonly used by law enforcement and CB radio enthusiasts articles alike to abbreviate certain key phrases to increase communication efficiency. In this article, we’ll recap the history behind the codes as well as show more of their usage that maybe you might use or hear around! 

First developed in 1937 and fully adopted in 1974, the codes were used by American police to shorten key phrases, however, it wasn't particularly standardized, it was held more of something police officers understood. It would later be replaced by the APCO Project 14 Aural Brevity Code in 2006 to make the “10” codes a standard communication system. That said, here is a continued list of the “10” codes to look out for in your CB radio journey!
