caption_attribution_description: English: NANP area code 217 and its neighbours.
context_page_description: Area code 217 is the North American telephone area code for much of western and central Illinois. The 217 area code includes the state capital, Springfield, plus Champaign, Urbana, Decatur, Taylorville, Danville, Effingham, Quincy, Rantoul, and Jacksonville. 217 was one of the original area codes, which were created in 1947.
  Originally, 217 included most of Metro East, the Illinois side of the St. Louis metropolitan area. However, a slight boundary shift in 1951 moved most of the southern portion of Metro East to 618, leaving the northern portion in 217. The only other significant change in 217's boundaries was in 1957, when its northern portion was combined with part of area code 815 to form area code 309. Area code 447 is planned as an overlay for 217 beginning in 2021.
