There is some dispute on which sanctioning body is considered "major" enough to award championships. The "Big 4" sanctioning bodies are always included. They are arranged in order of foundation:
In May 2012, citing the number of vacancies in various weight classes as primary motivation, The Ring unveiled a new championship policy. Under the new policy, The Ring title can be awarded when the No. 1 and No. 2 fighters face one another or when the Nos. 1 and 2 contenders choose not to fight one another and either of them fights No. 3, No. 4 or No. 5, the winner may be awarded The Ring belt. In addition, there are now six ways for a fighter to lose his title: lose a fight in his championship weight class; move to another weight class; not schedule a fight in any weight class for 18 months; not schedule a fight in his championship weight class for 18 months, even if fighting at another weight class; not scheduling a fight with a top 5 contender in any weight class for two years; or retiring.
Many media outlets and members are extremely critical of the new championship policy and state that if this new policy is followed The Ring title will lose the credibility it once held.
The International Boxing Organization (IBO) is sometimes included in the list of major boxing organizations.
Besides the IBO, there are other sanctioning bodies. They are: World Professional Boxing Federation (WPBF), International Boxing Association (IBA), International Boxing Council (IBC), International Boxing Board (IBB), International Boxing League (IBL), International Boxing Union (IBU), Global Boxing Association (GBA), Global Boxing Council (GBC), Global Boxing Federation GBF, Global Boxing Organization (GBO), Global Boxing Union (GBU), National Boxing Association (NBA), Transcontinental World Boxing Association (TWBA), Universal Boxing Association (UBA), Universal Boxing Council (UBC), Universal Boxing Federation (UBF), Universal Boxing Organization (UBO), UNIBOX, United States Boxing Council (USBC), World Athletic Association (WAA), World Boxing Board (WBB), World Boxing Championship Committee (WBCC), World Boxing Foundation (WBFo), World Boxing Institute (WBI), World Boxing League (WBL), World Boxing Network (WBN), World Boxing Union (WBU).
The following are the lists of boxers who have won four different titles in four totally different categories of weight.
This list is credited for boxers who have won championships in boxing from major sanctioning bodies and The Ring.
Example: Thomas Hearns won his first belt at 147 pounds, later he captured the 154 crown, he got the 175 belt and he finally won the 160 title.

This list is credited for boxers who have won championships in boxing from major and minor sanctioning bodies.
The first column of the extreme left (Major titles only) refers to championships won from only major boxing entities (WBC, WBA, IBF, WBO) and The Ring/Lineal. They are the organizations that generally considered as the 'real' ones.
The second column of the extreme left (Minor and Major titles) refers to any championships won from professional 'minor' boxing associations that are not yet well respected by the general boxing fan or public at 'world' level.
