Illinois State University, the state's oldest public university, operates under dedicated ZIP code 61790 in McLean County, Illinois. Governor William H. Bissell signed the law creating Illinois State Normal University on February 18, 1857, establishing it as a normal school for training teachers. Abraham Lincoln played a pivotal role in securing the financial documents that enabled the university to be located in Bloomington-Normal, beating out competing bids from Peoria, Washington, and Batavia. The town of Normal was actually named after the university in 1865.
The university became one of the first normal schools in the nation to offer a collegiate education in 1907 and was the first institution in Illinois to offer graduate-level work for teachers in 1944. It dropped Normal from its name in the mid-1960s while expanding into a multipurpose institution. Postal records show 129 ZIP+4 codes routing to this campus near Downtown Normal.
