There were no official conference changes in effect for the 2018 season, but FCS independents did return due to teams changing conferences or changes.
Liberty left the Big South Conference after the 2018 season to become an FBS independent. Idaho dropped from the FBS Sun Belt Conference to rejoin the FCS and the Big Sky Conference. Idaho was previously in the Big Sky prior to the 1996 season.
Campbell moved from the Pioneer Football League to the Big South. Hampton left the MEAC and North Dakota left the Big Sky to become FCS independents. North Dakota was moving into the Missouri Valley Conference in a two-year process, but their Big Sky games counted for their opponents.
