Northern sides

• All the sides that took part in the Final rounds were arbitrary promoted to 1945–46 Serie B with the exception of Varese that asked to take part to the regional leagues because its home stadium was destroyed by bombardment.
• Other 21 sides were promoted by the FIGC considering final placing, financial situation, previous sport merits, geographical representation, and, last but not least, if they had suffered wrongs made by the Fascist regime.
• *Girone A: Treviso
• *Girone B: Ferrara, Mantova, Suzzara and Trento
• *Girone C: Como, Crema, Seregno and the reborn Pro Sesto, that later absorbed the clubs Falck Sesto San Giovanni and Giovani Calciatori Sestesi.
• *Girone D: Gallaratese, Legnano, Vigevano and Vogherese
• *Girone E: Casale, Cuneo and Pro Vercelli
• *Girone F: Manlio Cavagnaro Sestri
• *Girone G: Panigale, Piacenza and Reggiana
• *Girone H: Cesena
• Istrian sides had to leave the league after annexation of the region by Yugoslavia. The teams from Rijeka/Fiume, Pula/Pola, and later Izola/Isola d'Istria were integrated in an Istrian tournament in 1945 and in the Yugoslav pyramid in 1946.
• All the relegations obtained on the pitch were cancelled, let alone cases of financial difficulties or dissolution.

  Southern sides

• Salernitana, promoted to Serie B at the end of the season, was admitted directly to 1945–46 Serie A.
• All the other teams were admitted to 1945–46 Serie C's Southern league, let alone sides with financial difficulties.
