In Ch. 3, how does Wiesel capture the sense that he is robbed of his identity at Auschwitz?

In Chapter 3 of "Night", Elie Wiesel captured the sense of being robbed of his identity through a series of horrific events. It starts when an inmate advises them to lie in order to not be sent to the crematory. Then they arrive at the barracks and they are stripped down, disinfected with gasoline, and they have their heads shaved. The narrator and his father are given prisoner numbers as tattoos, and a prisoner uniform. Wiesel describes his identity being erased when his prison tattoo "A-7713" is used to replace his name.
