WAccording to the Encyclopedia of Camps and Ghettos, there were 23 main concentration camps, of which most had a system of satellite camps. Including the satellite camps, the total number of Nazi concentration camps that existed at one point in time is at least 1,000, although these did not all exist at the same time.
WThe expansion of Flossenbürg concentration camp led to the establishment of subcamps, the first of which was established at Stulln in February 1942 to provide forced labor to a mining company. Many of them were located in the Sudetenland or across the border in the Protectorate of Bohemia and Moravia. The vast majority were established after 1 March 1944. Initially, the subcamps were not involved in armaments production, which changed in the second half of 1944 due to a large influx of available prisoners and the activities of the Jägerstab, which sought to increase German aircraft production. The Jägerstab's dispersal of aircraft production spurred the expansion of the subcamp system in 1944 and resulted in the establishment of the two largest of the subcamps, at Hersbruck and Leitmeritz. In the second half of 1944, 45 new camps were created, compared to three camps in the previous six months. The staffing these new camps was increasingly filled by Luftwaffe soldiers, Volksdeutsche SS men, and SS women, for the subcamps containing female prisoners. By April 1945, 80% of the prisoners were at the subcamps. Of all the concentration camp systems, Flossenbürg's subcamp system was one of the three most important to the economy of Nazi Germany, along with Dachau's and Mauthausen's.

WBelow is an incomplete list of SS subcamps of Neuengamme camp system operating from 1938 until 1945. The Neuengamme concentration camp established by the SS in Hamburg, Germany, became a massive Nazi concentration camp complex using prisoner forced labour for production purposes in World War II. Some 99 SS subcamps were part of the Neuengamme camp system, with up to 106,000 inmates. The number of prisoners per location ranged from more than 5,000 to only a dozen at a work site. Beginning in 1942, inmates of Neuengamme were also transported to the camp Arbeitsdorf. "Toward the ends of the war three times more prisoners were in satellite camps than in the main camp" wrote Dr. Garbe of the Neuengamme Memorial Museum. Several of the subcamps have memorials or plaques installed, but as of 2000, there was nothing at 28 locations.
WNazi concentration camps in Norway were concentration camps or prisons in Norway established or taken over by the Quisling regime and Nazi German authorities during the German occupation of Norway that began on 9 April 1940 and used for internment of persons by the Nazi authorities. 709 prison camps or concentration camps, [including some death camps,] were counted by a project that had Randi Bratteli, as an advisor. Another source has claimed that there were around 620 prison camps.
WThe following is a list of subcamps of the Sachsenhausen concentration camp established by Nazi Germany. The main camp, with around 50 barracks for slave-labour prisoners, was located 35 kilometres (22 mi) from Berlin, and operated between 1938 and April 22, 1945. During World War II the prisoners included Germans, Poles, Soviet POWs, Roma, and later Jews. It is estimated that the number of victims of Sachsenhausen was 30,000–35,000. Dozens of subcamps of Sachsenhausen existed directly in the capital city, serving individual business operators and factories.

WStutthof was a Nazi concentration camp established by Nazi Germany in a secluded, marshy, and wooded area near the small town of Stutthof 34 km (21 mi) east of the city of Danzig in the territory of the Free City of Danzig. The camp was set up around existing structures after the invasion of Poland in World War II and initially used for the imprisonment of Polish leaders and intelligentsia. The actual barracks were built the following year by prisoners.
