Area code 801 serves northern Utah, including major cities such as Salt Lake City, Ogden, Provo, and Sandy. It is one of the original area codes established in 1947 and initially covered the entire state before being split by 435 in 1997. Due to continued growth, especially around the Salt Lake Valley, area code 385 was introduced as an overlay in 2008, requiring ten-digit dialing. The 801 region is a hub for government, tech companies, higher education, and outdoor recreation. 801 remains a prestigious and widely recognized area code in Utah, especially for established businesses and long-term residents.
