Area code 307
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 it sparsely populated, Wyoming is one of only 12 states (as of 2012) to only have one area code. Under current projections, it will likely stay that way until beyond 2040.
