[1] The disputed territories once again became part of France after World War I and Schlettstadt joined that country's football competition in 1920 as Sportclub Sélestat in the regional top-flight Division d'Honneur Alsace.

The region was re-conquered by Nazi Germany early in World War II and SV Schlettstadt resumed its former place in German football as part of the first division Gauliga Unterelsass in 1940.

They made a losing appearance in the qualifying round of play for the Tschammerspokal, predecessor of today's DFB-Pokal (German Cup) in 1941, and then performed poorly in regular season competition over the next two years.

FC Sélestat remains active today and has departments for badminton, bowling, handball, swimming, and volleyball.

As of the 2007–08 season, the footballers play in Promotion A, Group D, of the Ligue d' Alsace - Bas Rhin (IX).
