A nine-digit numeric identifier issued by Dun & Bradstreet that the federal government once required for SAM.gov registration and contract award. The Data Universal Numbering System was retired as the federal standard on April 4, 2022, replaced by the government's own 12-character Unique Entity Identifier (UEI), ending reliance on a third-party provider.

The combined set of federal policies, processes, and technologies used to verify who a person or system is, issue and manage the credentials that prove it (such as PIV cards), and control what systems, data, or facilities they are permitted to access. ICAM underpins zero trust architecture and is a common compliance requirement in federal IT and cybersecurity contracts.

A 12-character alphanumeric identifier assigned to an entity through SAM.gov that serves as its primary ID across federal procurement, contract award, and financial assistance systems. Effective April 4, 2022, the UEI replaced the legacy DUNS number, is generated directly within SAM.gov, and never expires even though the underlying registration must be renewed annually.
