Resource: GSA Publishes Q&A About Upcoming Entity ID Rollout

The U.S. General Services Administration (GSA) recently published a set of questions fielded from users, along with answers, about upcoming changes to the unique entity identifier used to do business with the government.

Beginning in December 2020, the D-U-N-S® number will be replaced by a “new, non-proprietary identifier” requested in, and assigned by, the System for Award Management. This new identifier is being called the Unique Entity Identifier (UEI), or the Entity ID.

Q&A Resource

Learn more about the Entity ID rolloutBelow are some examples from the new GSA Q&A resource:

Q: Will the GSA automatically assign the new UEI or does the vendor have to take action to register?
A: Existing registrants will be automatically assigned a new UEI. New registrants will be assigned a UEI as part of their SAM registration.

Q: For entities that receive a subgrant from a recipient of a federal award, will they be required to obtain a unique identifier from SAM.gov?
A: Yes. Sub-awardees will need to obtain a UEI to adhere to regulations. Instead of going to D&B for a DUNS number like they do today, the sub-awardee would go to SAM.gov to request a UEI. They will not be required to complete the full entity registration process.
