In the late 1990s to 2000s, Reggina have been alternating between the top two levels of the Italian league system. They reached the Italian top division Serie A for the first time in 1999. Two years later, they lost a relegation playout to Verona, being consequently relegated to 2001–02 Serie B. Reggina finished third in Serie B in 2002, earning a return to Serie A. In 2003, Reggina survived a relegation playout against Atalanta. They would spend the next 7 years maintaining their Serie A status until their eventual relegation in the 2008–09 season.
