A list case is a request in which more than one name is submitted for action. The manner in which NPRC responds to such cases does not depend on the fact that it is a list case, but what type of information is requested. Multiple SF 180s, Request Pertaining to Military Records, received in the same envelope, are considered to be a list case and will be processed individually. The procedures for routing and determing what, if any, special handling will take place in responding to a list case are set forth in the NPRC source document.
