and 12 from USL PRO. The remaining 34 spots in the tournament field were filled by amateur teams from the Adult Council category–16 from the Premier Development League, eight from U.S. Adult Soccer Association regional qualifying, eight from the National Premier Soccer League, one from US Club Soccer and one from the United States Specialty Sports Association. The process for determining the site for the Open Cup tournament semifinals and final was changed in 2013. In past years, the sites for the final three matches of the tournament had been determined through a sealed-bid process, but in 2013 the hosts of those games were determined by a coin flip. Home teams throughout the entire tournament were determined by random selection. Since 2008, the champion of the U.S. Open Cup has earned the right to play in the CONCACAF Champions League. The first team to represent the U.S. as Open Cup champion was 2007's winner, New England Revolution.

This last change was proposed by the Houston Dynamo, which were the senior club to Rio Grande Valley FC Toros in the first such arrangement in the U.S. game; that arrangement ended after the 2021 season, and those two teams would be drawn against each other in 2022.

In 1999, U.S. Soccer honored patron Lamar Hunt by changing the official title of the tournament to the Lamar Hunt U.S. Open Cup. The winners of the tournament were awarded the Dewar Cup, donated by Sir Thomas Dewar for the promotion of soccer in the United States in 1912, until it was retired due to poor condition in 1979.
