The woman, who worked as a telegraph operator in Auschwitz, would be tried in a court for minors because she was under 21 at the time of alleged crimes, the agency said.
A court in the northern German city of Kiel is to decide whether to proceed with a trial next year, taking both the charges against her and her health into consideration, DPA said, quoting the city's chief prosecutor, Heinz Dollel.
Dollel did not name the woman but said she belonged to an all-female unit that helped the Nazi SS in concentration camps, and that she was accused in connection with events between April to July 1944.
Those three months correspond to a time when huge numbers of Hungarian Jews were murdered in the gas chambers of the Auschwitz-Birkenau concentration camp.
In July, a 94-year-old former SS officer Oskar Gröning, was sentenced to four years in jail as an accessory to murder in 300,000 cases in which Hungarian Jews were sent to the gas chambers between May and July 1944.
Known as the “Bookkeeper of Auschwitz”, his case was expected to be one of the last Holocaust trials.
Gröning served as an accountant at Auschwitz, sorting and counting the money taken from those killed or used as slave labour, and shipping it back to his Nazi superiors in Berlin.
Some 1.1 million people, most of them European Jews, perished between 1940 and 1945 in the Auschwitz-Birkenau camp before it was liberated by Soviet forces.
