Wyo

WYO is a three-letter acronym that can refer to several different subjects, depending on context. The most common usage is as an informal shorthand for the U.S. state of Wyoming. In travel writing, branding, and casual references, "WYO" signals Wyoming quickly and compactly. It is not the official United States Postal Service abbreviation for Wyoming; that is WY. However, WYO appears in business names, logos, and tourism materials as a mnemonic link to the state.

In broadcasting and media, WYO is sometimes used in station call signs or on-air branding to indicate Wyoming affiliation. U.S. radio and television stations use call letters that begin with W or K, and some Wyoming outlets incorporate WYO into their branding to emphasize regional identity. As with many three-letter combinations, the exact meaning of WYO in a given setting depends on local usage.

WYO also appears as an acronym for organizations, programs, or companies whose names start with W, Y, and O. Because these uses are diverse and localized, there is no single definition beyond the common shorthand for Wyoming or a branding element associated with particular entities.

If you encounter WYO in a particular article, advertisement, or product, consult surrounding text for the intended meaning—whether it refers to Wyoming, a broadcasting entity, or a specific organization.
