It has an area of about 154,000 square metres, of which 144,000 square meters are located on a single underground floor, making it the world's largest underground shopping mall. The mall is located at Samseong-dong served by Samseong Station on Seoul Metro Line 2, at the intersection of Teheranno and Yeongdong Dae-ro. The COEX Mall is adjacent to the COEX Convention & Exhibition Center, which is part of the COEX complex, run by the Korea International Trade Association (KITA).
Along with hundreds of shops, the mall houses two food courts, Megabox (movie theatres), COEX Aquarium, a large bookstore, and the Kimchi Field Museum.
