Explore all 5,000 federal contractors with USAspending.gov award data

Large contractors are often registered in USAspending.gov's SAM.gov-linked recipient data under multiple legal-entity names and Unique Entity Identifiers (UEIs), one company can appear here as several separate rows (for example, a parent corporation and its individually-registered business segments). We show each registered entity as USAspending reports it rather than guessing which registrations belong to the same ultimate parent, so when sorting by Total Awards, a single well-known company's combined federal spending may be split across more than one row here.

According to USAspending.gov, maintained by the U.S. Department of the Treasury under the Digital Accountability and Transparency Act of 2014, this directory currently tracks the 5,000 top contractors by total obligation amount, see our methodology for the full source detail.
