In team sports, the number, often referred to as the uniform number, squad number, jersey number, shirt number, sweater number, or similar (with such naming differences varying by sport and region) is the number worn on a player's uniform, to identify and distinguish each player (and sometimes others, such as coaches and officials) from others wearing the same or similar uniforms. The number is typically displayed on the rear of the jersey, often accompanied by the surname. Sometimes it is also displayed on the front and/or sleeves, or on the player's shorts or headgear. It is used to identify the player to officials, other players, official scorers, and spectators; in some sports, it is also indicative of the player's position.
The first use of jersey numbers is credited to a football team from New Zealand called the Nelson Football Club, who began wearing numbered jerseys in 1911. The numbers were used to help the spectators identify the players on the field, as well as to help the referee keep track of fouls and other infractions.
The International Federation of Football History and Statistics, an organization of association football historians, traces the origin of numbers to a 1911 association football match in Sydney,[1] although photographic evidence exists of numbers being used in Australia as early as May 1903 in a Fitzroy v Collingwood Australian rules football match.[2] Player numbers were used in a Queensland vs. New Zealand rugby match played on 17 July 1897, in Brisbane, Australia, as reported in the Brisbane Courier.[3]
