The Department of Defense Activity Address Code (DoDAAC) is a six-position code that uniquely identifies a unit, activity, or organization that has the authority to requisition, contract for, receive, have custody of, issue, or ship government-owned assets, or fund/pay bills for materials and/or services. The first positions of the code designate the particular Service/Agency element of ownership. These codes are particularly important for U.S. Government financial, contracting, and auditing records. The codes are used across the entire Federal Government when ordering supplies from the supply system using MILSTRIP, FEDSTRIP, or DLMS procedures; and for all contracts and orders. When assigned for activities outside the Department of Defense, the codes are often referred to as AACs. The code is comprised of different types of address information and other codes which are instrumental in facilitating business processes. See DLM 4000.25, volume 6, chapter2.
A DoDAAC is the business standard code used to identify an activity within DoD and Federal Agency business systems that span all functional domains of procurement/acquisition, financial management and accounting, supply, property, maintenance, transportation, readiness, human resources, etc. See DLM 4000.25, volume 6, Chapter 2.
