The federal government is moving away from using the DUNS number and is replacing it with a new non-proprietary identifier, the Unique Entity Identifier, UEI. On April 4, 2022, the federal government will stop using the DUNS number to uniquely identify entities registered in the System for Award Management (SAM). At that point, entities doing business with the federal government will use a Unique Entity Identifier (UEI) created in SAM.gov. 

To support this transition, HRSA’s Electronic Handbooks (EHBs) are being updated to enhance all fields that are labeled as DUNS number fields to UEI fields and are updating the associated processes, such as organization registration pages.
