History. In 1910, Penn began manufacturing tennis balls in Jeannette, Pennsylvania. Penn has a subsequent history of innovation in tennis ball design: In 1922, Penn makes the first pressurized ball cans.

Ganim says choosing the right racquetball depends on the type of tournament in which you'd like to compete. “Most events are indoors, so the green and the purple balls are far and away the best choices,” he says. “These are also ideal for intermediate and advanced-level recreational players.

One unique aspect of racquetball is that protective eyewear is mandatory. This is because the speed with which the ball flies around the court can reach above 100 mph! You'll need to keep your eyes well protected with glasses made from strong, durable materials; safety-certified is even better!

The same goes for Dunlop, Penn, and other brands. So why is there a printed number on each tennis ball? The answer is for the purpose of identification. When playing on a court, you will definitely experience your tennis ball rolling, bouncing (or flying for beginners) to the court next to you.

The numbers on PENN balls, or any other balls for that matter, are for identification purposes only, nothing more. When your ball rolls onto the court next to you knowing which ball is yours can be determined by the number on it. The numbers on balls are not a rating system--a PENN #1 is no different than a PENN #4. J.

I have a strix on one and he said well I also have a Swick's on one. We would not know whose ball is who unless. We put another identifiable mark which is generally a dot or two dots on the ball.

However, there is neither a special code nor a meaning related to these numbers. All tennis balls are the same within their brand. For example, all Wilson tennis balls have the same properties whether the printed number on them are1, 2, 3 or 4. The same goes for Dunlop, Penn, and other brands.
