SAM.gov Update: Unique Entity Identifier & Searching in SAM.gov

In April 2022, the federal government will stop using the DUNS number to uniquely identify entities registered in the System for Award Management (SAM).

SAM.gov also provides the ability to search for entities and individuals so you can determine if they have been suspended or debarred. It is also used to submit service contract reports for some federal contracts.

Federal Unique Entity Identifier (UEI)

  • Entities that conduct business with the federal government will begin to use a Unique Entity Identifier (UEI) created in SAM.gov.
  • The UW’s UEI is now available and visible
    • DUNS 605799469, the UEI is HD1WMN6945W6
    • DoEd Only – DUNS 042803536, the UEI is NFJ3CMQ4B418
  • Grants.gov is displaying and auto-populating the UEI on applications
    • Enter either the DUNS number or UEI on the application, depending on sponsor

You will start seeing UEI as a field name. Stay tuned to sponsor information on using the UEI.

Why Search in SAM?

We encourage campus to use SAM to determine if entities or individuals have been debarred or suspended by the federal government before we work with them.

You do NOT need an account to search for exclusion records.


Join us at the July 8th, 2021 MRAM for more information and a walk through on searching SAM.
