Identification of inmates in Nazi concentration camps instance of classification system
Identification of inmates in Nazi concentration camps was performed mostly with identification numbers marked on clothing, or later, tattooed on the skin.  More specialized identification in Nazi concentration camps was done with badges on clothing and armbands.Numbers
A practice was established to tattoo the inmates with identification numbers. Prisoners sent straight to gas chambers didn't receive anything. Initially, in Auschwitz, the camp numbers were sewn on the clothes; with the increased death rate, it became difficult to identify corpses, since clothes were removed from corpses. Therefore, the medical personnel started to write the numbers on the corpses' chests with indelible ink. Difficulties increased in 1941 when Soviet prisoners of war came in masses, and the first few thousand tattoos were applied to them. This was done with a special stamp with the numbers to be tattooed composed of needles. The tattoo was applied to the upper left part of the breast. In March 1942, the same method was used in Birkenau.The common belief that all concentration camps put tattoos on inmates is not true. The misconception is because Auschwitz inmates were often sent to other camps and liberated from there. They would show a number, but it came from their time at Auschwitz.
Metal stamps turned out to be impractical, and later numbers were tattooed with a single needle on the left forearm.
The tattoo was the prisoner's camp entry number, sometimes with a special symbol added: some Jews had a triangle, and Romani had the letter "Z" (from German Zigeuner for "Gypsy"). In May 1944, the Jewish men received the letters "A" or "B" to indicate particular series of numbers.  For unknown reasons, this number series for women never began again with the "B" series after they had reached the number limit of 20,000 for the "A" series.
