The area code 447 is located in Champaign, Illinois.
Area code 447 serves Champaign, Illinois, and the wider central Illinois region as an overlay to long-standing area code 217. It covers a mix of college towns, farm communities, and the state capital, making it an important hub for education, business, and government. Introduced as an overlay in 2021, 447 helps meet demand for new phone numbers without changing existing 217 numbers. Callers in the region use 10-digit dialing for local calls.
Major cities and communities in the 217/447 area include:
Beyond Champaign’s busy campus and research parks, the overlay also reaches major landmarks like the Abraham Lincoln Presidential Library and Museum in Springfield. New mobile and landline numbers across these communities may be issued with 447, while older lines often keep 217—both work in the same places. This shared coverage keeps local calling simple and preserves the region’s long history with 217.
