Smartling Locale Codes

This article is for Account Owners and Project Managers.

Each language you configure in a Smartling project has a display name and an underlying locale code. Display names appear in the dashboard. Locale codes are required when connecting content platforms to Smartling via a connector or API, or when importing TMX files.

Smartling locale codes are based on two ISO standards:

• Language codes follow ISO 639-1 — the international standard for two-letter language codes (e.g., en for English, fr for French).
• Country codes follow ISO 3166-1 — the international standard for two-letter country codes (e.g., 
  US for United States, FR for France).

A full Locale ID combines both standards using a hyphen: [language-code]-[country-code] (e.g., 
en-US, fr-FR).

A full list of supported locales is available in Supported Languages.

How to View Locale Codes for a Project
