FAQ
What is a locale code?
A locale combines a language and often a region—like en-US or de-DE—used in hreflang, formatting APIs, and translation workflows.
How to find language and region codes?
Browse the locale atlas by country or language tag to see official codes, display names, and related variants.
What is the difference between en-US and en-GB?
Both are English but en-US targets United States conventions while en-GB targets United Kingdom—important for spelling, dates, and hreflang.
How to use locale codes for internationalization?
Pick BCP 47 tags for UI translation files, hreflang alternates, and Accept-Language headers so users get the correct regional experience.
