ISO 3166-1-alpha-2 is the standard for country codes. It defines two-letter codes that are unique to each country. For example, the country code for the United Kingdom is GB
, the country code for France is FR
, and the country code for
Spain is ES
.
ISO 639 is the standard for language codes. It defines two-letter and three-letter codes that are unique to each language. For example, the two-letter language code for English is en
, the two-letter language code for French is fr
, and
the two-letter language code for Spanish is es
.
The locale formatIso is a way of combining a language code and a country code to represent a specific linguistic and cultural context. There are two main locale formats:
The BCP 47 formatIso separates the language code and country code with an underscore. For example, en_US
represents English spoken in the United States, fr_FR
represents French spoken in France, and es_ES
represents Spanish spoken in
Spain.
The ISO 3166-1-alpha-2 formatIso uses the ISO 3166-1-alpha-2 country code instead of an underscore. For example, en-US
represents English spoken in the United States, fr-FR
represents French spoken in France, and es-ES
represents Spanish
spoken in Spain.
