Notable past contestants
- Nick Fradiani, who auditioned with his band Beach Avenue, later tried out for season 14 of American Idol. He won the show on May 13, 2015.
- Season 9 is only the third time auditions were not held in Chicago, Illinois.
- Season 9 is the first season since Season 1 not to feature a Vegas Round.
- Season 9 introduced the Golden Buzzer. Each judge can hit it only once through the season, and it makes an act go through regardless of votes.
- The Red Buzzers were almost never used during the live shows, with only one performance being buzzed (intentionally). This is the fewest number of live show buzzes in any season.
