GSA’s Big Changes in 2020, Part 4: DUNS to UEI

Government Contracts Navigator

In addition to Federal Supply Schedule consolidation, GSA is replacing the official identifier federal government contractors use. Specifically, GSA is transitioning from and will stop using the Dun & Bradstreet (“D&B”) proprietary system for verification and validation of entities registering to do business with the federal government. Effective December 2020, GSA intends to have transitioned all government systems away from using D&B Data Universal Numbering System numbers (“DUNS”) and instead using new Unique Entity Identifiers (“UEI”). The UEI is a new, nonproprietary identifier that will be assigned through GSA’s System for Award Management (“SAM”) registration process.

Since as early as the 1960s, the federal government has contracted with D&B to provide DUNS numbers to companies seeking to contract with the federal government. Just like a CAGE (Commercial and Government Entity) code, an entity seeking to contract with the government must first contact D&B and obtain a DUNS number. A DUNS number is a unique nine-digit identifier for each entity performing or seeking to perform federal government contracts. Only after obtaining a DUNS number can a company then register in SAM. If a company needs to change its legal business name or physical address, it is must make such changes through D&B. Only after D&B updated a contractor’s DUNS record and made the data available to SAM could a contractor update its SAM registration.
