Quaranta has played internationally for the Under-17 and Under-20 United States national soccer teams, but while he was dominant for the U-17's, he was not able to secure a starting place on the U-20's (although he did play in the 2003 FIFA World Youth Championship). After coming back from injuries in 2005, Quaranta received his first cap for the senior team July 7, 2005 in a Gold Cup match against Cuba. He converted a penalty kick in the United States' shootout victory over Panama in the Gold Cup championship game. In 2009, Quaranta was named to the United States roster for that year's edition of the CONCACAF Gold Cup. On July 8, 2009 he scored his first international goal against Honduras during a 2–0 victory in CONCACAF Gold Cup group play.
