815 Area Code in Illinois, United States

Description

Area code 815 is one of the original area codes from 1947 and serves northern Illinois outside of Chicago, including cities like Rockford, Joliet, Crystal Lake, and Ottawa. Over time, population growth led to the introduction of overlay code 779 in 2007, and ten-digit dialing is now mandatory in the region. The 815 area blends suburban sprawl with agricultural communities, and is home to many manufacturing and logistics businesses. The region also serves as a transition zone between Chicago’s outer suburbs and rural Illinois. Despite the overlay, 815 remains a highly recognized and respected area code, often used in regional branding and local identity.
