Goodbye DUNS: System for Award Management Full Transition to New UEI Next Week
Client Alert | 2 min read | 03.28.22
As of April 4, 2022, the federal government will stop using the Dun & Bradstreet (D&B) Data Universal Number Systems (DUNS) Number to uniquely identify entities and will fully transition to using the Unique Entity Identifier (UEI). All entities will be using the UEI number for SAM and other government systems (including FPDS.gov, eSRS.gov, FSRS.gov, FAPIIS.gov, and CPARS.gov). DUNS Numbers will no longer be searchable or viewable in SAM. Those already registered in SAM should not need to take any action.
Purpose
The change is intended to allow for competition in the unique entity validation process by reducing the burden that would be associated with changing the vendors confirming that an entity is unique. Now SAM will generate the UEI number so it is vendor independent. The government will be able to compete and award contracts to do the unique entity validation process rather than be obligated to use D&B or any other particular vendor.
Timeline
The deadline to request a new DUNS Number or update existing entity information at D&B is March 29, 2022 at 5 p.m. EST. SAM.gov will be down beginning April 1 at 8:00 p.m. EST until no later than April 4 at 9:00 a.m. EST. During the transition, other government systems will experience intermittent downtime between March 31 and April 3.
Actions
No specific action is required for any entities already in SAM (active or inactive) and moving forward companies will no longer be required to update their DUNS registration (for instance in the event of a name change or address change) before updating SAM. Those registering in SAM after April 4, 2022 or seeking a UEI after April 4, 2022 will request a UEI through SAM.gov.
Businesses can view their SAM UEI for each entity registered in SAM by logging into SAM and navigating to the entity’s registration page. The SAM UEI is in the upper left corner under the DUNS currently, but the DUNS reference should be removed as of April 4, 2022.
SAM.gov has provided FAQs, videos, and an interactive graphic to help stakeholders understand the impacts of the UEI transition, new processes, and required actions.

Federal Court Blocks Trump Administration Policies Restricting Wind and Solar Permitting
A coalition of regional clean energy trade associations — including RENEW Northeast, Alliance for Clean Energy New York, Southern Renewable Energy Association, and Interwest Energy Alliance — along with the Green Energy Consumers Alliance (GECA), filed suit in December 2025 against the Department of the Interior (DOI), the Bureau of Land Management, the Bureau of Ocean Energy Management, the U.S. Fish and Wildlife Service (USFWS), and the Army Corps of Engineers. The complaint alleged that five agency actions, issued in response to a series of executive orders and presidential memoranda beginning on January 20, 2025, violated the Administrative Procedure Act (APA) by arbitrarily halting or restricting federal permitting for wind and solar energy projects. Plaintiffs sought a preliminary injunction to halt enforcement of these policies while the litigation proceeds. See Renew Northeast, et al. v. U.S. Dep’t of Interior, et al., No. 25-cv-13961-DJC, (D. Mass. Apr. 21, 2026) ECF Dkt. 89.
