After World War I the Combination was reduced to a single division. The club finished as runners-up in 1919–20, and the following season the club made an unsuccessful bid to join the Third Division North of the Football League. However, they won the Combination for the first time in 1921–22 and in 1928–29 reached the first round of the FA Cup for the first time losing 3–1 at home to Lincoln City. The following year they won the Combination for a second time and reached the FA Cup first round again this time losing 4–1 at New Brighton. The first round was reached again in 1930–31, 1931–32 and 1933–34, but the club lost on each occasion. Back-to-back league titles were won in 1934–35 and 1935–36, and in 1937 the club adopted its current name, Lancaster City F.C., after the town was given city status as part of King George VI's coronation celebrations.
