" TATTOOED NUMBERS, AS BLOOM had already established, were used to identify prisoners at just one concentration camp—the Auschwitz complex in Upper Silesia—and then just from 1941 onward. Only prisoners selected for work received a serial number, Epstein explained. Those who were sent directly to the gas chambers—including the elderly, the weak, and children—were not tattooed, although in the early days of the camp those who were in the infirmary or marked for execution were also tattooed on the chest using a metal stamp made up of interchangeable centimeter-long needles that allowed the tattoo to be created using a single blow, after which ink was rubbed into the wound. The digits were generally tattooed on the outer side of the left forearm, although some prisoners from transports in 1943 received tattoos on the inner forearm. The numbering sequences used varied over time, according to intake and the nature of the prisoners involved. An AU series denoted a Soviet prisoner, a Z series a Gypsy. A and B sequences up to 20,000 were used to identify male and female prisoners arriving at the camp after 1944, although an administrative error resulted in the B series exceeding 20,000. The Nazis’ original intention was to get as far as the final letter of the alphabet if required. "
