NDC: 217

This is the National Destination Code(NDC):217 page list. Its detail is as below.
Area code 217 is one of the original 86 area codes created by AT&T and the Bell System in 1947. It originally served central Illinois. To avoid exhausting all possible phone numbers in this area code, relief planning has begun. It is considered, "in jeopardy"which means that it is possible that the supply of numbers could be exhausted before an overlay can be created or the area code splits. Currently, the largest city it serves is Springfield, IL, and it overlaps coverage areas with area code 447.
