DA Form 3964, Classified Document Accountability Record is an official form used by the Department of the Army Information Security Program and designed as a single-entry active or inactive document-control register. The form will commonly accompany a classified document and is used to bring a document "under control" according to local procedures. The record is usually used either as a documented receipt, a certificate of destruction or a document-control copy.
The latest version of the document - sometimes incorrectly referred to as the DD Form 3964 - was released by the Department of the Army (DA) in July 1979 and replaces the November 1972 edition of the form. An up-to-date DA Form 3964 fillable version can be downloaded below or can be found on the APD Forms website.
Additionally, the DA Form 4011 (Telecommunications Center Delivery List) is used by message centers as a multiple-entry control register. The AE Form 380-5A (Multiple Classification Message Destruction Record) may be used as a multiple CD for messages.
