Angerer made her international debut for Germany against the Netherlands in August 1996. However, after five matches in quick succession she was only used sporadically thereafter. Angerer was Germany's second choice goalkeeper behind Silke Rottenberg for almost a decade, winning six major titles as a reserve player without having played in a single game, including the 2003 FIFA Women's World Cup, two Olympic bronze medals in 2000, 2004, and three UEFA European Championships in 1997, 2001 and 2005.
