Pickleballs are similar to wiffleballs but an official USAPA Approved pickleball is not a wiffleball.
Page 14 of the official USA Pickleball Rule Book has pickleball ball specifications.
What is the difference between Indoor Pickleball Balls and Outdoor Pickleball Balls?
Indoor pickleball balls often have larger holes and fewer holes. Outdoor balls often have smaller holes and more holes.
Either indoor or outdoor balls may be used in either environments, but ball manufacturers recommend various balls based on different play surfaces.

“The Tournament Director will choose the tournament ball. The ball selected for play in any USA PICKLEBALL-sanctioned tournament must be named on the official list of approved balls posted on the USA PICKLEBALL website: USA Pickleball.org.”
What is the pickleball ball made of?
Most pickleballs are made of Durable PE Plastic or Polypropylene Plastic. They must have a smooth surface wtih no texturing or contouring.
The balls must be a single, solid color.
Approved balls are allowed to have identification markings such as the manufacturer’s name or logo.
Official balls are allowed to have a slight seam or ridge as long as it does not impact flight characteristics.
For recreational play, practice, or beginners, I don’t find the difference between a standard wiffleball and an official pickleball to impact the quality of game play.
I wouldn’t stress out about finding a USA Pickleball approved ball unless I was planning on playing in an official tournament.
