Wyoming State in United States
Description
Wyoming, the Equality State, is known for its wide-open plains, Yellowstone National Park, and cowboy heritage. It is the least populous U.S. state, making it a haven for solitude, nature, and Western traditions.

Wyoming is one of the few states still covered by a single area code 307. In service since 1947, area code 307 remains adequate due to the state’s small population and rural layout, ensuring reliable coverage from Cheyenne to Jackson Hole.
