The USGA publishes a list of conforming golf balls every month. The list contains the golf ball’s pole marking, the color, the seam marking, the construction, the spin rating, the number of dimples, the country and the name of the manufacturer. This information is vital to the serious golfer because a golf ball must be on the USGA list in order to be allowed for play in USGA tournament play.
The list can be helpful to golf ball collectors to assign a date when a golf ball was first introduced into the marketplace. Additionally, the list can help the average golfer decide which golf ball is best suited for his or her swing speed and ability to control unintentional side spin.
Here are the USGA conforming golf ball lists (PDF), covering the years from 2002 to 2019, that I have downloaded from the internet.
