The 10 Codes for CB Radios

Whether you’re a CB enthusiast or an enjoyer of police televison you’ve likely heard the “10” codes. These are used to represent common phrases, commonly utilized by law enforcement and CB radio transmissions. It was developed between 1937-1940 and later in 1974 was expanded by the Association of Public-Safety Communications Officials-Internation (APCO). While it was used by police in America during this time, it was eventually discontinued by the federal government in 2006 due to a lack of standardization. It was later replaced by what is called the APCO Project 14 Aural Brevity Code, which is a standarized version of the “10” codes.
