A-7713 is the concentration camp identification number tattooed onto Elie Wiesel’s arm at Auschwitz-Birkenau. In his landmark 1958 memoir Night, Wiesel describes the moment this number replaced his identity: “I became A-7713. From then on, I had no other name.” The number has become one of the most recognized symbols of the dehumanization carried out during the Holocaust, representing the systematic erasure of individuality that defined the Nazi camp system.
A-7713 in Elie Wiesel’s Night
Wiesel was fifteen years old when he arrived at Auschwitz with his family in 1944. After being separated from his mother and sisters at the selection platform, he and his father were deemed fit for forced labor rather than sent immediately to the gas chambers. That distinction is important: only prisoners selected for work received serial numbers. Those sent directly to be killed were never registered at all.
The tattooing marked a turning point in the memoir. Before Auschwitz, Wiesel was Eliezer, a devout Jewish teenager from Sighet, Romania, with a family, a community, and a spiritual life. After the tattoo, he became a number on an arm. The passage captures something central to the camp experience: the deliberate stripping away of everything that made a person human. Name, history, relationships, dignity. All replaced by digits inked into skin. Wiesel uses this moment to show how the Nazi system didn’t just imprison people but attempted to destroy their sense of self entirely.
The Tattooing System at Auschwitz
Auschwitz was the only Nazi concentration camp that systematically tattooed prisoners. The practice began not as a tool of humiliation but as a bureaucratic solution to a grim problem: identifying the bodies of registered prisoners who had died. According to the United States Holocaust Memorial Museum, the SS originally marked prisoners by stamping their camp serial number across the chest with indelible ink, particularly for those in the infirmary or slated for execution.
The first method of tattooing used a metal stamp fitted with interchangeable needle-tipped numbers, each roughly one centimeter long. The entire serial number could be punched into the prisoner’s left upper chest in a single blow, and ink was rubbed into the bleeding wound. When this proved impractical, the SS switched to a single-needle device that pierced the outlines of each digit individually. The location eventually moved to the outer side of the left forearm, though some transports in 1943 had numbers placed on the inner side of the left upper arm.
The numbering system itself went through multiple series. The first series of prisoner numbers began in May 1940 and continued until January 1945, ending at 202,499. Additional series were introduced over time for different categories of prisoners. By the end of the camp’s operation, Auschwitz authorities had assigned more than 400,000 serial numbers. The “A” prefix in Wiesel’s number identified the series he was registered under, one used for Jewish prisoners arriving during the massive Hungarian transports of 1944.
Dehumanization as a Deliberate Process
The tattoo was only one step in a calculated process. Prisoners had their heads shaved, their clothes taken, and their possessions confiscated. They were forced into identical striped uniforms. Families were separated on arrival. Every element of personal identity was systematically removed and replaced with uniformity and anonymity. The tattoo made this erasure literal and permanent, turning a person’s body into a ledger entry.
Wiesel’s description of becoming A-7713 resonates because it captures the psychological dimension of this process. Losing your name is not just an administrative act. It signals that the system no longer recognizes you as a person with a past or a future. You exist only as a unit of labor, tracked by number until you are no longer useful. This is why the passage has become one of the most frequently cited moments in Holocaust literature: it distills an enormous, almost incomprehensible atrocity into a single, concrete experience that any reader can grasp.
Why A-7713 Still Matters
After surviving the camps, Wiesel went on to become a writer, professor, and human rights advocate. He received the Nobel Peace Prize in 1986. Throughout his life, A-7713 remained visible on his forearm, a permanent physical record of what he endured. He chose not to have it removed.
The number serves a dual purpose in how we remember the Holocaust. It is both evidence of a specific crime against a specific person and a symbol of what happened to millions. Wiesel’s willingness to write about the experience, to name the number and describe what it meant, turned A-7713 into a piece of shared cultural memory. For students reading Night for the first time, it is often the detail that makes the scale of the Holocaust feel real. Six million is an abstraction. One boy losing his name is not.
