Release of UEI / EVS Specifications - Groups 1 & 2

As you may be aware, GSA will be making changes to the unique entity identifier (UEI) that is used to do business with the federal government. Currently, we use the proprietary DUNS number as the UEI for doing business with the government. We are moving to a new, non-proprietary identifier that will be requested in and assigned by the System for Award Management (SAM.gov).

To learn more about the transition from DUNS to a non-proprietary UEI, visit www.GSA.gov/entityID

Many systems outside of the GSA interface with award data and information, including UEI data. To help our partners across the federal government and the public, we have published the first and second set of UEI/EVS specifications. Group 1 includes:

  • The beta.SAM Entity Management API has updated schemas for what will be a second version of the API. This API allows interfacing systems to pull information about the entity via an automated process. Field differences between versions are marked as v1 (current version) or v2 (future version). The specifications can be obtained at https://open.gsa.gov/api/entity-api/.

  • The SAM Entity Management Web Services will not be updated to incorporate UEI or new EVS changes. All users of this web service will need to migrate to the beta.SAM Entity Management API to retrieve UEI and new EVS information.

  • The SAM public RESTful API will not be updated to incorporate UEI or new EVS changes. All users of this RESTful API will need to migrate to the beta.SAM Entity Management API to retrieve UEI and new EVS information 

 

Group 2 includes:

 

  • The beta.SAM Exclusions API has updated schemas for what will be a version 2 of the API.  This API allows interfacing systems to pull information about the exclusions via an automated process.  Field differences between versions are marked as v1 (current version) or v2 (future version). Go to https://open.gsa.gov/api/exclusions-api/ to find the specifications.

  • The SAM Exclusions Search Web Services will not be updated to incorporate UEI or new EVS changes. All users of this web service will need to migrate to the beta.SAM Exclusions API to retrieve UEI and new EVS information regarding exclusions via interface.

 

Additional sets of UEI/EVS specifications will continue to be provided in the following weeks.  By December 30, 2019, IAE will release its testing plan and will complete the issuance of updated technical specifications for interfacing systems so your technical teams can finalize their plans to accommodate these interface changes and begin the development required to test with IAE. 

 

Please view the IAE’s EntityID Webinar which contains the history of this effort as well as questions and answers about the transition at EntityID.  User questions specific to testing of these interfaces should be directed to newsamtesting@gsa.gov. Users who have specific questions regarding the SAM-generated UEI or entity validation services should reach out to entityvalidation@gsa.gov.
