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. By April of 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

For details on why this transition is happening, please refer to the GSA website,

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.

What is the UEI?

The Unique Entity Identifier is the new 12-digit alphanumeric identifier that will be provided by registration to all entities who register to do business with the federal government (including the existing entities). This is the identifier which is replacing the use of the DUNS.

What does this mean for me?

There is no action needed on your behalf. The UEI will be automatically generated by and imported into the EHBs.

During the transition, you can search for your organization using either the DUNS or UEI. However, on all updated fields you will see the UEI listed.

The EHBs updates will be rolling out in phases. The first phase is rolling out in two parts on June 10, 2021 and October 21, 2021, and the second phase is forthcoming in late 2021/2022 and will include updates to all remaining pages that mention the DUNS.

Note: In the event the UEI is not available, the DUNS number will still appear in the EHBs.

What pages are being updated?

June 2021: Application Tracker Widget, Organization Registration, Grantee My Portfolio pages

Examples of the UEI Change

EHBs Registration to an Organization

When you register to an organization, you will see the DUNS search field updated to UEI. You can search by UEI or DUNS to find the organization.

The tooltip next to UEI provides helpful information about the new field: You may use this option if you know your organization's Unique Entity Identifier (UEI) or DUNS Number. The system will automatically search for the organization in SAM if it is not found in EHBs.
