Area code 801 serves the Salt Lake City metropolitan area in northern Utah, including cities like Ogden, Provo, and Sandy. As one of the original area codes from 1947, it has deep ties to the state’s early communication infrastructure. Due to population growth, it was overlaid by area code 385 in 2009, requiring ten-digit dialing. The region is home to state government, a thriving tech scene often dubbed the “Silicon Slopes,” and headquarters of the Church of Jesus Christ of Latter-day Saints. Area code 801 remains a respected and historically significant code, especially in business and civic life across northern Utah.
