== Indicating regional variant ==

When it is necessary to indicate region-specific language, an [[ISO 3166-1 alpha-2]] country code, or [[UN M49]] region code, should be added to the language tag, taking care to preserve capitalization. For example, Portuguese (<code>pt</code>) as used in Brazil (<code>BR</code>) could be represented as <code>pt-BR</code>, and Spanish as used in Latin America as <code>es-419</code>.

Additionally, language, script, and region codes can all appear in the same tag. For instance, the code <code>zh-Hant-TW</code> should be used for Chinese text written with [[Traditional Chinese characters|Traditional Han characters]], containing words or expressions specific to [[Taiwan]]:

* <code><nowiki>Taiwan ({{lang|zh-Hant-TW|臺灣}}, {{transliteration|zh|Táiwān}})</nowiki></code>
: Taiwan ({{lang|zh-Hant-TW|臺灣}}, {{transliteration|zh|Táiwān}})
