Standardized codes for languages, countries, regions, scripts, and related data play a crucial role in software localization. They allow us to represent information uniquely, accurately, and consistently, reducing confusion and making the localization process more efficient.

Below are standards that define the most commonly used codes in software localization:

ISO 639-1 language codes

ISO 639-2 language codes

ISO 639-3 language codes

ISO 15924 script codes

ISO 3166-1 alpha-2 country codes

UN M49 area codes
