Located next to the commercial underground office park known as Meritex Lenexa, the National Archives and Records Administration operates this Federal Records Center, also in a mined limestone cavern, with a separate driveway and entrance. It is one of 18 Federal Records Centers, some of which are underground, which store hard copy and digital data from dozens of federal agencies, including the IRS, Defense Department, and the Social Security Administration. These facilities are separated into nine regions that cover the nation, though the storage facilities are often not located in the corresponding regions. This facility houses material for the region that includes Iowa, Kansas, Missouri, and Nebraska, as well as the IRS processing center in Ogden, Utah.
