In its current format, the Italian Football Championship was revised from having regional and interregional rounds, to a single-tier league from the 1929–30 season onwards. The championship titles won prior to 1929 are officially recognised by FIGC with the same weighting as titles that were subsequently awarded. Similarly, the 1945–46 season, when the round-robin was suspended and the league was played over two geographical groups due to the ravages of WWII, is not statistically considered, even if its title is fully official. All the winning teams are recognised with the title of "Campione d'Italia" ("Champion of Italy"), which is ratified by the Lega Serie A before the start of the next edition of the championship.
