The tournament is played on the green clay courts atLTP-Daniel Island (which contains the 10,200-seat Credit One Stadium) onDaniel Island inCharleston, South Carolina, US.[7] From its inception in 1973 to 2000, the tournament was held at theSea Pines Plantation onHilton Head Island with the exception of 1975 and 1976 when it was played onAmelia Island off the coast of Florida. The event moved to Charleston, and specifically Daniel Island, in 2001.[8]
From 1973 to 2015, the title sponsor wasFamily Circle magazine, which had made it the longest-running title sponsor in professional tennis.[9] Chinese automakerGeely, which has a factory in nearby Berkeley County for their Volvo brand, took over sponsorship from 2016 to 2021.[10][11]Credit One Bank, which had sponsored the 2020 tournament, became the title sponsor of both the tournament and stadium in July 2021.[12] Also in 2021, two tournaments were organised in consecutive weeks as a makeup tournament for those cancelled by pandemic restrictions. TheMedical University of South Carolina sponsored the event.[13]
From 1990 to 2008, the tournament was classified as aWTA Tier I event. In 2009, it was downgraded to aWTA Premier tournament. It celebrated its 40th year in 2012[14] by naming its main stadium court in honor ofBillie Jean King.[15][16] With the reorganization of the WTA's schedule in 2021, the tournament became aWTA 500 tournament.
