Area code 219 is located in northwest Indiana, in the United States. It covers the Indiana side of the Chicago metropolitan area, including cities such as Gary, Hammond, East Chicago, Merrillville, Crown Point, Valparaiso, and Michigan City.
It is one of Indiana’s main area codes for the far northwest corner of the state, along Lake Michigan. The code is used across several counties there, especially Lake, Porter, La Porte, Newton, and Jasper.
For callers, 219 is a normal North American area code, so it uses the standard +1 country code. The area is commonly associated with Northwest Indiana and is often called “the Region” by locals.
If a phone number starts with 219, it usually points to that part of Indiana rather than Chicago itself, even though the area sits right next to the Illinois border.
