After graduating from Weymouth North High School (1989), Corddry went to the University of Massachusetts Amherst (1989–93).

While at UMass, Corddry pledged the Theta chapter of Theta Chi fraternity.

In January 1994, Corddry moved to New York City. His early paying jobs included working as a security guard at The Metropolitan Museum of Art and handing out menus for a Mexican restaurant. He eventually landed acting jobs, including a year-long tour with the National Shakespeare Company. He trained in improv at the Upright Citizens Brigade Theatre in New York City, performing regularly as a member of the sketch comedy group "The Naked Babies" (with John Ross Bowie, Brian Huskey, and Seth Morris); and he spent two years with the sketch comedy group "Third Rail Comedy". Corddry's first notable television appearances were on Comedy Central's Upright Citizens Brigade (1998–2000).
