10 codes originated in the USA and are CB radio lingo mostly used in English-speaking countries. However, no matter which codes are used in your country, be aware that there are local dialects in every urban area and region. You have to listen to others to learn the phrases and codes in your area. And not everyone knows or uses 10-codes, so be prepared for some people to not understand you.
