Skip to content The Unique Entity Identifier (UEI) has revolutionized federal contractor identification across GSA and SBA applications. Issued through SAM.gov at no cost, this 12-character alphanumeric code replaces the DUNS number, streamlining entity validation processes. Contractors must maintain active SAM registrations with accurate UEI information to remain eligible for federal contracts, grants, and specialized programs like 8(a) and HUBZone. Recent updates have reduced registration frequency requirements while maintaining strict compliance standards for government procurement opportunities.
How UEI Transforms Federal Entity Identification
The Unique Entity Identifier (UEI) revolutionizes the federal identification system by replacing the previously used DUNS number with a government-issued credential. This transformation represents a significant shift from proprietary identification to a government-managed system, streamlining entity validation processes across federal awards.
Unlike the DUNS number, which required third-party validation through Dun & Bradstreet, the UEI is issued directly through SAM.gov at no cost to applicants. This change creates a more competitive environment for entity validation services while reducing administrative burdens for organizations seeking federal funding. The UEI serves as a business’s identifier comparable to a social security number in federal systems. Maintaining accurate registration information is essential for accessing federal contracts and grants.
The UEI integration simplifies the identification process by automatically assigning identifiers to existing SAM registrants and incorporating UEI issuance into new registrations. This systematic approach enhances transparency, consistency, and efficiency in federal award management.
Critical SAM Registration Requirements for Government Contractors
With UEI implementation changing federal identification processes, government contractors must now focus on System for Award Management (SAM) registration requirements.
The UEI transition demands contractors’ heightened attention to SAM compliance for federal procurement eligibility.
The SAM compliance framework establishes mandatory registration for all entities seeking federal contracts, grants, or funding. Regular system checks help maintain compliance status and prevent potential financial penalties.
The registration process begins at SAM.gov, where contractors must first obtain a Unique Entity Identifier. Contractors must submit accurate business information and complete certifications regarding size, ownership, and SBA program eligibility. The UEI is a 12-character alphanumeric code that replaced the previously required DUNS number.
Recent regulatory changes have eased requirements, eliminating continuous registration throughout pre-award. Under FAR amendment FAC 2025-01, contractors now need SAM registration only at bid submission and contract award. This change from the FAR Council directly corrects misinterpretations that arose from the 2018 amendment regarding SAM registration requirements.
Non-compliance risks remain significant. Contractors with lapsed or inaccurate registrations face proposal invalidation and contract ineligibility.
Best practices include regular information updates and reviewing registration data before each bid submission.
UEI Integration With GSA and SBA Application Processes
Every federal contractor must now incorporate the Unique Entity Identifier (UEI) into their GSA and SBA application workflows since the government-wide shift from DUNS numbers. This integration has streamlined entity management across federal agencies, creating a more efficient application process. Step-by-step guidance helps organizations navigate the UEI acquisition requirements smoothly.
For GSA requirements, businesses must include their UEI in all proposals and contract submissions. The identifier is mandatory for GSA contract awards, partnership programs, and participation in e-commerce platforms. All entities must also maintain active SAM registrations to remain eligible for federal financial assistance programs.
Similarly, SBA eligibility criteria mandate UEI registration for all contracting assistance programs. Applications for specialized SBA certifications—including 8(a), HUBZone, WOSB, and SDVOSB—require a valid UEI through the certify.SBA.gov portal. Small businesses must also include appropriate NAICS codes when registering in the system to properly identify their industry classification.
Annual updates to SAM registration guarantee continued compliance with both agencies, maintaining eligibility for federal opportunities without interruption.
Frequently Asked Questions
How Do I Transfer My UEI When My Business Structure Changes?
When a business structure changes, entities must update their information in the System for Award Management (SAM).
The registration process involves modifying the legal business name and address in SAM, which will automatically update the UEI association.
Organizations should notify relevant federal agencies about these changes to maintain compliance.
No manual UEI transfer is required, as the system handles this automatically when proper updates to the business information are completed.
Can Foreign Entities Obtain a UEI for U.S. Federal Contracting?
Foreign entities can indeed obtain a UEI for U.S. federal contracting.
The foreign eligibility criteria allow international organizations to register through the SAM.gov system, even when exempt from complete SAM registration for awards under $500,000.
However, these entities must still meet basic contracting requirements mandated by federal regulations.
Foreign businesses seeking U.S. government opportunities should initiate the UEI registration process through SAM.gov, regardless of their location or country of origin.
What Happens if My SAM Registration Expires During Contract Performance?
When a SAM registration expires during contract performance, significant registration implications arise. The government may lose authorization to continue working with the contractor, disrupting contract continuity.
Existing agreements face interruptions, especially during modifications or administrative processes. Payments might be delayed, causing financial strain.
Additionally, the contractor becomes ineligible for new contract opportunities. To maintain compliance and avoid disruptions, contractors should implement proactive monitoring practices and renew registrations well before expiration dates.
How Do Joint Ventures Register for a Single UEI?
Joint venture registration for a single UEI requires creating a distinct legal entity. The joint venture must:
- Form a separate legal entity with its own name.
- Register in SAM as a new entity, specifically selecting “joint venture” as the entity type.
- Apply for a unique UEI through SAM.gov.
- List all individual partners as immediate owners.
This registration process guarantees the joint venture is recognized as its own entity for federal contracting purposes, separate from the individual partner companies.
Is UEI Information Publicly Accessible Through SAM.Gov?
Yes, UEI information is partially accessible to the public through SAM.gov, though uei accessibility concerns exist regarding complete data availability.
While basic entity information can be viewed by anyone, certain details remain restricted for privacy reasons.
Sam.gov transparency issues arise when users seek thorough UEI datasets, as these typically require API access or specific permissions.
For legitimate business purposes, public users can search and view limited entity profiles without registration.
