Why am I getting text messages from area code 307?
Texts from 307 numbers follow the same pattern as calls — mostly local businesses and services. Treat any text asking for payment or credentials as suspect regardless of the code.
The common patterns are a wrong-number opener that turns into conversation, an unsolicited job offer, and a crypto or investment tip. Do not reply, do not follow the link, and forward the message to 7726 (SPAM) to report it to your carrier.
Who works in the Cheyenne area?
Area code 307 covers the entire state of Wyoming, one of the few codes to serve a whole state unchanged since 1947, and Cheyenne is its capital and business anchor. The city's economy rests on government, the railroad, and the military: the State of Wyoming and Laramie County are the largest employers, Union Pacific has run through Cheyenne since the town was founded on its tracks in 1867, and F.E. Warren Air Force Base manages intercontinental ballistic missiles from the city's western edge. A newer layer is data centers, drawn by cheap land and power, with Microsoft operating a campus in the area, and a growing cluster of blockchain firms attracted by Wyoming's friendly corporate statutes.
Who lives in the 307 region
Cheyenne held 65,239 people in 2024, with a median household income of $78,839 and a poverty rate of 8.74 percent, low by national standards (Census ACS via Data USA). The population is 98.7 percent US citizens, and just 2.9 percent of residents were born abroad.

What a 307 number signals to a caller
Because 307 is statewide, the number says Wyoming rather than any one city, and residents treat it as a marker of belonging in a state of under 600,000 people. Callers describe business in Cheyenne, Wyoming as personal and handshake-driven, where reputations travel fast because everyone knows everyone. Government and rail run on formal procurement, but most local deals still start with a phone call answered by the owner.
