307 area code summary

Area code 307 covers the entire state of Wyoming and is one of the few remaining U.S. states with a single area code. Established in 1947, 307 includes Cheyenne, Casper, Laramie, Jackson Hole, and Gillette. Wyoming’s economy centers on energy (especially coal, natural gas, and wind), agriculture, and tourism, particularly in Yellowstone and Grand Teton National Parks. Cheyenne, the capital, supports government, military, and transportation industries. Laramie is home to the University of Wyoming and serves as the intellectual hub of the state. Jackson Hole attracts affluent visitors and residents, fueling luxury real estate and service sectors. With wide-open landscapes and a small population, the 307 area code is a badge of identity and independence. For ranchers, developers, outfitters, or regional businesses, a 307 number connects directly to Wyoming’s frontier heritage and emerging modern industries.
