zhHansSG

zh-Hans-SG is a locale tag used in computing to identify Simplified Chinese as written and used in Singapore. In the IETF language tag system, zh denotes Chinese, Hans indicates the Simplified Han script, and SG represents Singapore. The tag is used in software localization, web content delivery, and data tagging to signal that text should follow Singaporean conventions for Simplified Chinese rather than those of Mainland China or Taiwan.

Singapore's linguistic landscape includes four official languages: English, Malay, Mandarin, and Tamil. Chinese content in Singapore typically uses Simplified Chinese characters, which are common in official and educational materials, and a set of region-specific vocabulary and orthographic conventions. The zh-Hans-SG tag helps developers distinguish Singaporean Chinese content from zh-Hans-CN (Mainland China) or zh-Hant-TW (Taiwan), enabling appropriate font support, spellings, and formatting choices.

In practice, zh-Hans-SG appears in HTML language attributes, localization files, and software defaults when content is intended for users in Singapore. Locale data providers such as CLDR and IANA maintain registries for this tag, alongside related variants. The tag does not represent a distinct language, but a regional variant of Chinese for Simplified script used in Singapore.
