The Amateur Athletic Union of the United States Inc (EIN: 352458875) is a nonprofit organization distinct from the historic Amateur Athletic Union (AAU) founded in 1888. This entity operates under the name associated with the website primetimevolleyball.com, indicating a focus on volleyball activities and events.

While the original Amateur Athletic Union (AAU) is a well-established, multi-sport amateur athletics organization founded in 1888 that promotes sports and physical fitness across a broad spectrum of disciplines in the United States, the Amateur Athletic Union of the United States Inc with the specified EIN number appears to be a separate entity. The traditional AAU is noted for its extensive membership of over 900,000 athletes and coaches, its historical role in shaping amateur sports standards, and its long-standing mission under the motto "Sports for All, Forever."[1][2][3]

The organization associated with primetimevolleyball.com likely serves a more specialized role, focusing on volleyball programs, leagues, and tournaments. It operates as a nonprofit dedicated to amateur volleyball development, fostering skill growth, competition, and participation at various levels within the sport. This specialization differentiates it from the broader scope of the original AAU.

Due to the limited publicly available historical and operational information about this particular nonprofit (Amateur Athletic Union of the United States Inc, EIN: 352458875) beyond its volleyball focus, a comprehensive encyclopedic article would emphasize its volleyball-related mission and nonprofit status, distinguishing it clearly from the historic multisport AAU organization founded in the 19th century.

Note: The original Amateur Athletic Union (AAU) founded in 1888 is an extensive and historically significant amateur sports organization in the US. The entity described here is not the same as the 1888 AAU, which has its own well-documented history and organizational structure.[1][3]
