There are 67 teams representing 61 cities that have taken part in 90 Serie A championships in a single round that was played from the 1929–30 season until the 2021–22 season. Milan, Turin, Genoa, Rome and Verona are the five cities that hosted derbies. Internazionale is the only team that has played Serie A football in every season. The teams in bold compete in Serie A currently.
54 out of the 61 cities that host past Serie A clubs are present-day provincial capitals, while 7 not. The province of Forlì-Cesena is the sole one that was represented solely by a town which is not its capital. Consequently, 55 out the 107 provinces of Italy were represented in Serie A in their history, while 52 not yet.
This championship was disputed during the second World War and won by Vigili del Fuoco di La Spezia (V.V.F. Spezia, Spezia Firefighters). It was not recognized by the FIGC until 2002 and assigned to Spezia Calcio 1906, though Spezia's Scudetto is considered a "decoration".
This championship is not usually included in the statistics, because some of the southern sides that took part to the competition were Serie B teams, while northern Serie B teams played at the second level with the Serie C teams. Torino's scudetto is considered official.
