Area code 219 serves northwestern Indiana, including cities like Gary, Hammond, Merrillville, Valparaiso, and Michigan City. Nestled along the Lake Michigan shoreline and bordering Chicago, this region functions as a key part of the broader Chicago metropolitan economy. Historically known for steel production and industrial strength, 219 now includes a diversified economic base with logistics, education, and healthcare playing significant roles. Gary was once the epicenter of U.S. Steel, and while its population has declined, the city remains symbolically important and is seeing renewed attention through infrastructure investment and regional planning. Valparaiso and Merrillville provide suburban growth and home to institutions like Valparaiso University and Methodist Hospitals. The Indiana Dunes National Park adds tourism and natural beauty to the region, attracting visitors from nearby Chicago and beyond. As an area code with strong commuter ties, a 219 number reflects connection to both local communities and the broader Midwest economy. It’s a solid choice for professionals, small businesses, and service providers operating between Indiana and Illinois.
