Area code 307 is the only area code serving Wyoming, the least populous US state. Cheyenne is the state capital and largest city, sitting on the high plains near the Colorado border. Wyoming's economy is driven by energy production including coal, oil, and natural gas, plus tourism to Yellowstone and Grand Teton National Parks.
Across Wyoming, the 307 area code serves roughly 580,000 residents in 4 communities — including Cheyenne, Casper, Laramie, among others. Numbers in the 307 zone keep Mountaintime, so a local line rings during your customers' business hours and shows a familiar WY caller ID on every outbound call.
307 was first introduced in 1947 under the North American Numbering Plan. It remains an active geographic code today.
