Hannoverscher SC play in the Regionalliga Nord, the fourth tier in the German football league system, having been promoted from the Oberliga Niedersachsen in 2019.

After the end of World War I, Hannoverscher SC 02 reached the highest league, the Südkreisliga.

One year later, the HSC 02 won its division, but lost the championship match against Arminia Hanover 1–2.

As runner-up, a qualification match for the North German final round was played, which was won 6–2 against Bremer SV.

In the final round of the North German Championship, after a 1–2 opening defeat against Hamburger SV, they won 2–1 against Altona 93 and were chosen by the sports press as the secret favorite.

FV Sport Hannover also belonged to the founding members of the Südkreisliga in 1919, but mostly played against relegation.

After a close 3–2 victory at Eimsbütteler SV, they had to accept a 0–8 defeat against Holstein Kiel in the quarter-finals.

After World War II, the club settled at Constantinstraße, where the sports field was located between a gasometer and a rubbish dump.

According to legend, the treasurer of the club fled with the income from a friendly match against Arminia Hannover to save the money from the bailiff.

In 2016, the HSC secured its promotion to the Oberliga Niedersachsen two matchdays before the end of the season, but were relegated after only one year.
