'''Area code 307''' is the telephone [[area code]] in the [[North American Numbering Plan]] for the entire [[U.S. state]] of [[Wyoming]]. It is one of the 86 [[original North American area codes]] created by the [[American Telephone and Telegraph Company]] (AT&T) in 1947.

Because it is sparsely populated, Wyoming is one of only nine states (as of May 15, 2025) with only one area code.
