Federal Government to Replace DUNS Numbers with New Unique Entity Identifiers by December 2020

As you may know, a DUNS number is a unique, nine-digit number issued by Dun & Bradstreet that identifies an organization or business. Currently, many U.S. government agencies and other grant sponsors require that a grantee have both a DUNS number and U.S. Employer Identification Number (EIN) in order to accept any funding; however, in March 2019 the federal government announced it would be moving to a new, government-owned unique entity identification system—the SAM Managed Identifier (SAMMI)—as a replacement for the DUNS in all systems, including Grants.gov and eRA Commons. This change is slated to take effect by December 2020, when the System for Award Management (SAM) will become the central repository for the new SAMMI unique entity identifiers. Please note that OSP is aware of this upcoming change and will be working closely with our federal sponsors as additional information becomes available. For any questions or concerns, please contact your OSP specialist.
