DUNS has been replaced with UEI  

DLA has transitioned from the Data Universal Numbering System (DUNS) and replacing it with the SAM Unique Entity Identifier (UEI) to identify federal contractors and award recipients. 

As of April 4, 2022, DUNS is no longer used in federal-level procurement or financial assistance pre- and post-award processes. This transition allows the government to streamline the entity identification and validation process, making it easier and less burdensome for entities to do business with the federal government. The UEI is the new authoritative identifier at the federal level (including SAM, FPDS, CPARS, FAPIIS, eSRS, FSRS, and USASpending).

The CAGE code will still be required on entity registrations for purpose of all awards in SAM.

GSA has assigned UEIs to entities with existing registrations and/or debarments/suspensions in SAM and will continue to assign UEIs to new vendors.

DLA has made interface updates to accommodate this transition.  These updates now enable EBS to receive and store the new UEI from SAM.  The EBS vendor master has also been updated to include UEI.  Currently there are no issues pertaining to SAM UEI interfaces from a systems perspective.

As of June 21, 2021, DLA Land and Maritime has transitioned from Dun & Bradstreet (D&B) to Experian BusinessIQ to perform financial reviews. See related Message of the Day on DLA Today (CAC-enabled)

The Federal Service Desk also has additional training on this transition (search the “Knowledge Base” section).
