Area code 385 is an overlay for area code 801 in northern Utah, including cities like Salt Lake City, Ogden, and Provo. Introduced in 2008, it was implemented to support increasing demand in one of the state’s most densely populated regions. The overlay requires ten-digit dialing and is widely used for new mobile and business lines. Northern Utah is a hub for government, technology, education, and outdoor recreation. 385 plays a key role in expanding telecommunications infrastructure while preserving the identity of the original 801 area.
