By Karen Norris, Principal, Kanoco, Consulting



The Office of Management and Budget (OMB) and the General Services Administration (GSA) announced in July 2019 that the DUNS number would be phased out and replaced by a new Unique Entity Identifier (UEI) number by December 2020, and in October 2020 extended the transition to April 4, 2022. The incremental transition would occur as nonfederal entities would renew their registrations in the System for Award Management (

In fact, there are three new protocols in the works for, all of which significantly impact the ability to pursue and receive federal funds.  Federal agencies and nonfederal entities should note the new requirements and check registration renewals.

The new standard will require all federal agencies and nonfederal entities to create new fields in databases, financial systems, on federal, state, and local forms, and on multiple websites.

In 2019 the initial announcement identified a December 2020 target to complete the transition from DUNS to UEI through registration renewals; however, more time was needed, according to a GSA announcement October 26, 2020, to complete the process. The new timeline for completion is April 4, 2022, when the UEI number is scheduled to go live.

The Code of Federal Regulations (2 CFR 25) was also updated to reflect the pending change to the UEI number, final rule published in the Federal Register on August 13, 2020, effective November 12, 2020.

Nonfederal entities, therefore, should make a note of the date when their annual registration is due to renew, and monitor that process carefully to ensure successful receipt of the new UEI and completion of their renewals.

Nonfederal entities currently registered in should experience an automatic migration of their roles to using their same email address.
