Wyoming is served by a singular area code, 307, which has been in use since its establishment on January 1, 1957. This area code corresponds to the entire state, reflecting Wyoming’s low population density and geographical characteristics. As of the 2020 census, Wyoming had a population of approximately 578,000 residents, making it the least populous state in the United States.
The choice of a single area code helps simplify telecommunications in Wyoming, a state known for its vast open spaces and small urban centers. Major cities such as Cheyenne, Casper, and Laramie share the same area code, making local calls straightforward. Given its unique positioning, 307 also serves as a cultural symbol for many residents, representing not just their geographical location, but also their connection to the state’s identity.
Historically, the introduction of the area code was part of a nationwide initiative by AT&T to streamline long-distance calling processes and manage the growing demand for telephone services. In Wyoming, the system has remained unchanged, contrasting with states that have had to implement additional area codes due to population growth. This stability in telecommunications infrastructure contributes to Wyoming's unique rural character, where landline usage remains relatively high compared to urban areas with multi-area code systems. Overall, Wyoming’s area code exemplifies the state’s demographic and geographical dynamics within the broader context of telecommunications in the United States.

Wyoming has 1 area codes (307). These area codes are split between cities or states, so if you want to call to Wyoming, you need to know exactly where you would like to call.
The first 3 digits to call Wyoming may vary depending on where you want to call to, being one or the other depending on the region or city. Take a look at our listing above to find out which area code you need.
Calling Wyoming from another state in the United States is considered a long-distance call. Here’s how to make the call: First, dial the area code for Wyoming. Each state, and sometimes specific cities within a state, has unique area codes. Then, enter the 7-digit phone number of the person or business you’re trying to reach. If you’re calling from a landline, check with your provider, as long-distance charges may apply. However, most mobile carriers in the U.S. offer nationwide calling without additional fees. Alternatively, you can use VoIP or internet-based calling apps, like Skype, Zoom, or WhatsApp, to bypass traditional long-distance charges. The number you want to reach should look like this: 1-(AreaCode)-111-2222.
When making calls within the United States, dialing +1 depends on several factors. On most modern mobile phones, carriers automatically recognize the country code when calling within the U.S., so dialing +1 is usually not required; you can simply enter the area code followed by the phone number, such as 213-555-1234. If you’re using a landline, dialing 1 (the U.S. country code) before the area code and phone number is often necessary for long-distance calls; for example, calling from one state to another may require dialing 1-213-555-1234. When calling the U.S. from another country, dialing +1 is necessary, so a call from abroad would be formatted as +1-213-555-1234. VoIP and internet-based calling platforms, like Skype and WhatsApp, generally handle country codes automatically, making it unnecessary to dial +1 manually for U.S. numbers.
