ISO 639-2:1998 provides two sets of three-letter alphabetic codes for the representation of names of languages, one for terminology applications and the other for bibliographic applications. The code sets are the same except for twenty-five languages that have variant language codes because of the criteria used for formulating them.There are a number of suggestions for deciding whether to use a one-level (language only) or two-level (language-region) tag. They require some discussion and will be added here shortly. Language codes used as primary subtags are from ISO 639. Country codes used as secondary subtags (or tertiary if script tags are secondary) are from ISO 3166.
You can’t simply use random two-letter combinations that suit your fancy! While you can use hreflang language codes on their own, it’s best to use them together with the ISO 3166-1 alpha-2 hreflang regional codes. This helps give search engines a full picture of which language and geographical region a particular web page is meant for.
