Prisioners were only tatooed in Auschwitz. “Incoming prisoners were assigned a camp serial number which was sewn to their prison uniforms. Only those prisoners selected for work were issued serial numbers; those prisoners sent directly to the gas chambers were not registered and received no tattoos.
Initially, the SS authorities marked prisoners who were in the infirmary or who were to be executed with their camp serial number across the chest with indelible ink. As prisoners were executed or died in other ways, their clothing bearing the camp serial number was removed. Given the mortality rate at the camp and practice of removing clothing, there was no way to identify the bodies after the clothing was removed. Hence, the SS authorities introduced the practice of tattooing in order to identify the bodies of registered prisoners who had died.”

3)How did SS officers selected their victims?Support your answer
They had SS doctors on duty, to examine the incoming transports of prisoners. The prisoners would be marched by one of the doctors who would make spot decisions as they walked by. Those who were fit for work were sent into the camp. Others were sent immediately to the extermination plants. Children of tender years were invariably exterminated since by reason of their youth they were unable to work.
