Talking Like a Pro: An Ultimate Guide to 10-Code Communication

Most children enjoy a walkie talkie set because it allows them to talk and play with their friends however, as an adult, these devices can be really valuable if used correctly. With that said, it’s important to learn the common phrases and codes since it’s no longer all fun and games but you can utilize a radio more purposefully such as when going camping or traveling.


A Brief History of 10-Codes

Developed by the Association of Public-Safety Communications Officials-International (APCO), 10-codes or 10-signals are basically abbreviations that refer to common phrases used over the radio. In other words, instead of saying the entire sentence you just say a few numbers and the listener on the other end will know what you mean because they are globally recognized messages.

You might find some of these codes familiar since they’re used by law enforcement officials in movies. However, radio enthusiasts can learn and apply them as well. The main purpose of 10-Codes is to allow people who don’t have time to communicate or are in some kind of trouble to say what they need very quickly and effectively.
