Every powerlifting federation has its own "official" records. And there are a lot of powerlifting federations! Plus, many have state, national, and international records. The website Powerlifting Watch provides a compilation of records (to a degree) from multiple federations. I believe that area of their website requires a for-fee membership, however.
Where you live will somewhat dictate the options for what federations are active near you and what records are relevant to you.
