She had a total length of , a pressure hull length of , a beam of , a height of , and a draught of . The submarine was powered by two Germaniawerft F46 supercharged four-stroke, six-cylinder diesel engines producing a total of  for use while surfaced, two AEG GU 460/8-276 double-acting electric motors producing a total of  for use while submerged. She had two shafts and two  propellers. The boat was capable of operating at depths of up to . The submarine had a maximum surface speed of  and a maximum submerged speed of . When submerged, the boat could operate for  at ; when surfaced, she could travel  at . U-213 was fitted with five  torpedo tubes (four fitted at the bow and one at the stern), twelve torpedoes, one  SK C/35 naval gun, 220 rounds, and an anti-aircraft gun, in addition to five mine tubes with fifteen SMA mines.

U-213 carried out three war patrols during her career, ranging into the North Atlantic. One of them included the landing of an Abwehr agent, Alfred Langbein, on the Canadian coast near St. Martins, New Brunswick on 14 May 1942. The mission was termed Operation Grete; Langbein was instructed to report on the sailing of convoys. He failed to accomplish this, and surrendered to the authorities in September 1944 after running out of money. He was released after the end of the war. U-213 was a member of three "wolfpacks" during the war, as part of 'Schlei' from 1 February until 12 February 1942, 'Westwall' from the 2 to 12 March, and 'Pfadfinder' from the 2 to 27 May. During this period she suffered two attacks, one on 7 February 1942 from the escorts of convoy ON-63, which she was attempting to attack, which left the U-boat slightly damaged after attacks by depth charges; another was when the boat was surprised on the surface by a destroyer in bad weather in the Gulf of Maine, and was again slightly damaged by depth charges on 15 May. U-213 was sunk with all hands on 31 July 1942, while in the North Atlantic, east of the Azores, in a depth charge attack by the British sloops ,  and . Wolfpacks
