Locale code is a combination of ISO 639-1 language code and ISO 3166-1 country code. For example, en_SL is a locale code for English language in Sierra Leone. Locale codes are used to define the language and country settings for date, time, currency, and number formatting.

Locale codes are standardized by the International Organization for Standardization (ISO) and are widely used in software development.
