👉 The US Polo Association (USPO) is an association for polo players, including international teams. The word "USPO" comes from the United States Polo Club (UPC), which was established in 1859, but its name remains unchanged as of 2023. It has members who compete internationally, while the UPC was a governing body that regulated polo. The USPO promotes sportsmanship, integrity, and community through its activities.
