Area code 563 serves eastern Iowa, including cities such as Davenport, Dubuque, Bettendorf, and Clinton. It was established in 2001 after being split from the 319 area code, following growth in the Quad Cities and surrounding communities. The region encompasses a mix of industrial, riverfront, and educational centers, as well as scenic areas along the Mississippi River. Davenport and Dubuque are key cultural and economic drivers in this area. The 563 area code supports a wide range of residents, from urban professionals to rural farmers. Ten-digit dialing is required in some places, but the area code remains stable and recognized throughout eastern Iowa.
