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.
