The numbers on the golf balls do not indicate anything. The purpose of the number is to be able to identify the golf ball.
Most golf balls have a single digit number on them right next to the brand name.
The main reason that manufacturers put numbers on golf balls is to help golfers properly identify their ball while on the golf course.
Playing the wrong golf ball during a stroke, par or stableford competition results in a two-stroke penalty for the golfer who struck the wrong ball.
