|Purpose||Boxing sanctioning organization|
|Headquarters||Coral Gables, Florida, United States|
It is often considered a "minor" world championship as it is not recognized as a major world title by any of the "big four" governing bodies (WBA, WBC, IBF and WBO), who all recognize each other in their rankings and title unification rules.
The IBO was founded in 1988 and incorporated in Illinois in 1992 by John W. Daddono. The organization was later moved to Florida in 1996 and incorporated in Florida at that time. Ed Levine, who continues to serve as the organization's President became a partner and President of the IBO in 1999.
The organization received acclaim by implementing a computerized system 'The Independent World Boxing Rankings' in the late 1990s that removed subjective elements from the ratings in an effort to bring more credibility to the sport. From 2014 the organization now uses Boxrec, the independent boxing records keeping and computerized rankings website for IBO's rankings. Many marquee champions have held and continue to hold the International Boxing Organization World title.
If a fighter tests positive for banned substances after a bout, he is barred from a rematch.
The IBO permits only one champion per weight division. "We have never had more than one champion per weight division nor will we", according to its president Ed Levine.
If an IBO Inter-Continental champion successfully defends his title three times, he may receive a mandatory opportunity for the world title.
