In 1947–48 the team was promoted to Serie C but the team was forced to renounce to it because of economical problems. In 1948–49 the club played in Prima Divisione, in 1949–50 in seconda divisione.

In 1953–54 Bastia played in promozione regionale. After two years in Promozione the team was promoted in 1955–56 to IV Serie (Serie D) after winning the promotion playoff against Gubbio. In the first year in IV Serie the club managed to avoid relegation but at the end of the 1957–58 season the club was relegated to Promozione after losing relegation playoffs against Rotulea and Perugia.
Three seasons later Bastia won the Promozione Umbria championship but renounced to the promotion to Serie D. In the 1962–63 the team arrived 2nd in Promozione and won the Coppa Umbria.
