EsMX

esMX is a locale identifier used to signify the Spanish language as used in Mexico, primarily in computing and publishing. The code is commonly rendered as es-MX in IETF BCP 47 standards; some software ecosystems also reference it as esMX. It signals Spanish with Mexican regional settings, affecting translations, number and date formats, currency, and other locale-sensitive resources.

In practice, esMX encompasses vocabulary, spellings, and usage characteristic of Mexican Spanish. It differs from other Spanish variants, notably esES (Spain) and esAR (Argentina) in lexicon: for instance, everyday terms such as carro instead of coche, and computadora instead of ordenador. Date formats in many contexts follow day-month-year, and the currency is the Mexican peso (MXN).

The code is used by operating systems, applications, and websites to deliver localized content. This includes translated strings, locale-aware formatting, and regional data such as addresses, names, and sorting conventions. In software development, esMX resources may be organized in locale directories (for example language packs or resource qualifiers) and paired with other variants for fallback and pluralization rules.

EsMX functions as part of the broader Spanish language family and is one of many locale identifiers used worldwide. It helps ensure that users in Mexico receive translations and formatting that reflect local conventions.
