Returns the ISO 639-1 alpha-2 code, ISO 639-2/T (terminological) alpha-3 code, the ISO 639-2/B (bibliographic) variant when it differs, the English name, the native (endonym) name, the language family and writing direction (LTR / RTL / TTB). Useful for product engineers building locale pickers, content teams tagging translations, and i18n developers validating BCP-47 tags. Match strategy: 2 chars → alpha-2 exact; 3 chars → alpha-3 exact (terminological or bibliographic); longer → case-insensitive substring on name or nativeName. Runs entirely in your browser — your data is never sent anywhere.","category":"payment","categoryName":"Payment & cards","keywords":["iso 639 language codes","language code lookup","iso 639-1","iso 639-2","iso 639-3","language code to name","alpha 2 language code","alpha 3 language code","language family lookup","language direction rtl ltr","language native name","language code search","i18n language code"],"badge":"Lookup","url":"https://toolsly.tools/iso639-language-lookup","inputs":[{"type":"text","key":"query","label":"Code or name","placeholder":"en, eng, or 'spanish'","help":"Accepts alpha-2 (ISO 639-1), alpha-3 (ISO 639-2/T or 639-3), or a name fragment."}],"outputs":[{"key":"alpha2","label":"Alpha-2 (ISO 639-1)"},{"key":"alpha3","label":"Alpha-3 (terminological)"},{"key":"bibliographic","label":"Alpha-3 (bibliographic)"},{"key":"name","label":"Name"},{"key":"nativeName","label":"Native name"},{"key":"family","label":"Language family"},{"key":"direction","label":"Writing direction"}],"invocation":{"webUi":"https://toolsly.tools/iso639-language-lookup","api":null,"notes":"Currently invoked via the web UI at `webUi`.
