Locale identifiers, also known as locale codes or locale tags, are standardized strings used to uniquely identify a specific language and regional variant. They are crucial for software localization and internationalization, enabling applications to present information, such as dates, numbers, currency, and text, in a culturally appropriate format. A common format for locale identifiers is the BCP 47 standard, which typically consists of a primary language subtag followed by one or more optional region subtags, separated by hyphens. For example, "en-US" represents English as spoken in the United States, while "fr-CA" denotes French as used in Canada. The language subtag is usually a two-letter ISO 639-1 code, and the region subtag is often a two-letter ISO 3166-1 alpha-2 code. However, the standard allows for more complex structures including script subtags (e.g., "zh-Hans-CN" for Simplified Chinese in China) and variant subtags. Operating systems and programming languages often provide mechanisms for detecting and managing the user's current locale, allowing for dynamic adaptation of application behavior and content. Proper use of locale identifiers ensures a consistent and relevant user experience across diverse global markets.
