North American Area code 307 is the area code that serves the entire U.S. state of Wyoming. It is one of the original area codes created in 1947.
Because of its significantly low population, Wyoming is one of only twelve states (as of 2012) to only have one area code. Under current projections, it will stay that way until 2025.
