What are Ten Codes?

Ten Codes are abbreviations of common questions and answers used on all types of radio. Profession CB'ers use Ten Codes to send their message quickly and easily. Additionally, Ten Codes can be readily understood by stations which may be receiving you poorly or when a language barrier is present. Learning Ten Codes is most often done by their use. Copy this list of some of the most common Ten Codes and keep them near your radio. Use these Ten Codes in your daily communications and soon you will have most of them committed to memory!

Plain speech communications over public safety radio systems is preferred over the traditional 10-Codes and dispatch signals.  

 

APCO provided a core list of codes from 10-1 to 10-39. Other codes are optional and non-standard across jurisdictions and may be problematic if multiple organisations must respond to the same incident.  

 

Standardized codes are shown in bold.
