Professional soccer in the United States has a number of unique traits that are not apparent in any of the other prestigious soccer nations. Perhaps the most geographic of them is the implementation of conferences. The idea of conferences is found in all of the other American sports leagues but is also quite common in non-league soccer around the world.
What makes conferences important in American soccer is they determine who will make the playoffs. Like other professional sports leagues in America, clubs are placed into groups based on their geographic proximity and are in direct competition with the others in their group to qualify for the postseason. The USL Championship has gone through a number of different formats including a single table, multiple divisions, and now two conferences with varying numbers of teams qualifying for the postseason.
