Federal Government Transition from DUNS to UEI

As of April 4, 2022, the federal government discontinued using the DUNS number to uniquely identify entities. Previously, DNR grantees receiving federal funds needed to provide a DUNS number as part of the grant process. As of April 4th, grantees receiving federal funds will now have to provide a Unique Entity Identifier (UEI) created in (office website of the U.S. government). Entities registered in prior to April 4th already have their UEI viewable in The following website provides more information regarding the transition from DUNS number to UEI:

At this time, the DUNS field on the application has not been transitioned to accept the UEI number. Please include your UEI number in your application email.
