Locations for Area Code - 219

Area code 219 serves northwestern Indiana, including Gary, Hammond, Valparaiso, and the Lake Michigan shoreline. Introduced in 1948 as a split from 317, this region is part of the greater Chicago metropolitan area and has deep industrial and transportation roots. The steel industry, freight rail, and lakefront access give 219 economic significance. There are no overlays, so seven-digit dialing is still possible for local calls. Known for its blue-collar strength and regional identity, 219 carries weight in both industry and culture in “The Region.”
