GHIN.com features a handicap search tool that golfers can use to find handicap scores for local golfers throughout the United States. Golf clubs assign GHIN numbers and send information about golfers to the website, allowing them to post their scores on the site for potential challengers to see.
GHIN.com describes itself as the world's largest handicap computation service, with a network of 12,000 clubs and approximately 2.3 million individual golfers. The website gathers information from golf clubs about their members' scores and the relative difficulty of the courses in order to compute a handicap. A golfer's handicap score allows golfers of varying skill levels to compete on equal footing.
The handicap calculator on GHIN.com assigns a specific score to each golfer in the system and offers golfers the ability to derive the appropriate handicap for a game at any participating golf club's course with any participating golfer. The governing body of GHIN.com, The United States Golf Association, assigns slope ratings to various courses according to their difficulty.
Members of GHIN.com self-report their scores to the website, allowing the site to automatically calculate their handicaps. Unlike most competitive sports, the rules of golf do not provide an incentive for misleading scores since handicaps help both parties enjoy the rounds they play.
