DUNS Numbers Are No More as of Monday, April 4 

Beginning Monday, April 4, 2022, the federal government will transition to the Universal Entity Identifier (UEI) number for all entities doing business with it and will no longer use the DUNS number issued by DUN and Bradstreet to uniquely identify entities. The UEI is assigned by the U.S. General Services Administration (GSA) in the System for Award Management (SAM.gov).
