The Official Transition From DUNS to UEI

The transition from DUNS to the Unique Entity Identifier (UEI) marked a significant change in federal procurement processes. This shift, managed by the General Services Administration, was driven by the government’s need for a more efficient and cost-effective system. The transition timeline, key differences between DUNS and UEI, and the rationale behind this change reshaped
in federal contracting.
Government Rationale for Adopting the Unique Entity Identifier
The government adopted the Unique Entity Identifier (UEI) to streamline federal procurement processes and reduce reliance on third-party systems. This transition aimed to enhance data integrity, improve operational efficiency, and decrease costs associated with entity identification. The UEI system provided greater control over the identifier assignment process, enabling faster updates and more accurate tracking of entities engaged in federal contracts and grants.
Timeline and Key Dates of the DUNS Replacement
The transition from DUNS to UEI followed a structured timeline with key milestones. The General Services Administration (GSA) announced the change in 2019, setting April 4, 2022, as the official implementation date. This timeline allowed federal agencies and contractors to prepare for the transition, update systems, and adapt to the new identifier:
- 2019: GSA announces transition from DUNS to UEI
- 2020-2021: Preparation and system updates
- April 4, 2022: Official implementation of UEI
- Post-implementation: Ongoing support and refinement
The General Services Administration‘s Management of the UEI Shift
The General Services Administration (GSA) led the transition from DUNS to UEI, overseeing the implementation process and providing guidance to federal agencies and contractors. The GSA developed comprehensive resources, including training materials and technical documentation, to facilitate a smooth transition. They established a dedicated support team to address inquiries and challenges during the shift, ensuring minimal disruption to federal procurement activities.
Differences Between the DUNS Number and the UEI
The UEI and DUNS Number differed in several key aspects. While the DUNS Number was managed by a third-party company, Dun & Bradstreet, the UEI is generated and maintained directly by the government. The UEI consists of a unique 12-character alphanumeric code, compared to the 9-digit DUNS Number. This change allows for greater flexibility in identifier assignment and reduces costs associated with using a proprietary system. Additionally, the UEI integrates more seamlessly with existing government databases, enhancing data accuracy and
and contractors.
Navigating the DUNS to UEI Change in Federal Registries

The transition from DUNS to UEI in federal registries involved several key processes. Existing SAM registrants received automatic UEI assignments, while new entities followed specific procedures to obtain a UEI. This change impacted federal reporting systems and necessitated record updates across government platforms. Understanding these processes was crucial for entities engaged in federal procurement and assistance programs.
Automatic UEI Assignment for Existing SAM Registrants
Existing SAM registrants received automatic UEI assignments during the transition from DUNS to UEI. The General Services Administration (GSA) implemented a seamless process to assign UEIs to entities already registered in the System for Award Management (SAM). This automated assignment ensured continuity for organizations engaged in federal procurement activities and minimized disruptions to ongoing contracts and grants. The process involved mapping existing DUNS Numbers to the new 12-character alphanumeric UEI format:
DUNS Number | UEI Format | Assignment Method |
---|---|---|
9-digit numeric | 12-character alphanumeric | Automatic mapping |
Managed by Dun & Bradstreet | Generated by GSA | System integration |
External proprietary system | Government-owned identifier | Direct SAM update |
Procedures for New Entities Requiring a UEI in SAM.gov
New entities seeking to engage in federal procurement or assistance programs must obtain a Unique Entity Identifier (UEI) through SAM.gov. The process involves creating a SAM.gov account, providing essential business information, and completing a validation process. Once validated, the system generates a UEI automatically, enabling the entity to participate in federal contracting opportunities and grant applications. This streamlined procedure eliminates the need for a separate

Impact of the Transition on Federal Reporting Systems
The transition from DUNS to UEI significantly impacted federal reporting systems, requiring extensive updates to accommodate the new identifier format. Government agencies modified their databases, forms, and reporting tools to integrate the UEI, ensuring seamless data collection and analysis. This change necessitated adjustments in contract management systems, grant application portals, and financial tracking platforms across various federal departments, streamlining entity identification processes and enhancing data consistency in federal procurement activities.
Updating Records Across Government Platforms
The transition from DUNS to UEI necessitated extensive updates to records across government platforms. Federal agencies systematically revised their databases, procurement systems, and reporting tools to incorporate the new UEI format. This process involved updating existing contract and grant records, modifying form fields, and adjusting data validation protocols to ensure seamless integration of the UEI across all government platforms involved in federal procurement and

Post-Transition Landscape Using the Unique Entity Identifier

The post-transition landscape using the Unique Entity Identifier (UEI) has reshaped federal procurement processes. This section examines the current status of UEI integration in SAM.gov, advantages of the government-owned system, handling of historical DUNS data, and ongoing use of UEI for federal awards. These topics highlight the practical implications and benefits of the transition for entities engaged in federal
.
Current Status of UEI Integration in SAM.gov
The UEI integration in SAM.gov has been fully implemented, replacing the DUNS Number as the primary identifier for entities in federal procurement processes. SAM.gov now generates and manages UEIs internally, streamlining the registration and verification processes for businesses and organizations engaging in federal contracts and grants. This integration has enhanced data accuracy and reduced reliance on third-party systems, improving overall efficiency in federal award management.
Advantages of the Government-Owned UEI System
The government-owned UEI system offers several advantages over the previous DUNS Number system. It provides greater control and flexibility in managing entity identifiers, reducing costs associated with third-party services. The UEI system enhances data integrity and security, as the government directly oversees the generation and maintenance of identifiers. This centralized approach streamlines processes for federal agencies and contractors, improving efficiency in procurement activities and grant management.
How Historical DUNS Data Is Handled Now
Historical DUNS data remains accessible through archived systems and databases maintained by federal agencies. The General Services Administration has implemented measures to preserve historical records, ensuring continuity in tracking past federal awards and contracts. While new transactions utilize the UEI system, government entities can still reference DUNS information for legacy data analysis and compliance purposes, maintaining a comprehensive view of federal procurement history.
Ongoing Use of UEI for Federal Awards and Processing
The Unique Entity Identifier (UEI) has become integral to federal award processes, streamlining entity identification and verification across government agencies. Federal departments now use the UEI for all aspects of award management, including solicitations, contracts, and grant applications. This centralized system enhances data accuracy and efficiency in federal procurement activities, facilitating smoother transactions between the government and its contractors or grantees:
.
UEI Application | Benefit to Federal Awards |
---|---|
Entity Identification | Improved accuracy in recipient tracking |
Award Processing | Streamlined contract and grant management |
