Area code 307 is the telephone area code in the North American Numbering Plan for the entire U.S. state of Wyoming.[1] It is one of the 86 original North American area codes created by the American Telephone and Telegraph Company (AT&T) in 1947.[1]
Wyoming's sparse population has not required more than one area code for the state. As of May 2025, it was one of only eleven states with only one area code.[citation needed]
