Area code 712 was one of the
original three area codes for the state of Iowa established in 1947, and is the only one that still has its original boundaries. It is one of the few remaining original area codes (not counting those covering an entire state) that has never been split or
overlaid. Despite the proliferation of cell phones and pagers (particularly in Sioux City and Council Bluffs), it is projected to stay that way until at least 2031.
