When looking at the List of Conforming Golf Balls, you'll be struck by just how many golf balls are out there (and how many brands you've never heard of). What Conforming/Non-Conforming Mean If a golf ball does not appear on the list of conforming balls, it is most likely to be non-conforming. What does that mean? A non-conforming golf ball (or any non-conforming piece of golf equipment) cannot be used in any competition that is conduced under the Rules of Golf, nor in any round played under the Rules of Golf (such as rounds whose scores will be reported for handicap purposes). The golf ball standards in Appendix III of the Rules of Golf govern weight, size, spherical symmetry (the ball must be round, in other words), initial velocity and overall distance standard. If a golf ball does appear on the list of conforming balls, then it is "legal" to use that ball in any such competition or round. "Conforming" means the golf ball meets all the requirements set forth in the Rules of Golf's equipment standards as established by the USGA and R&A.
