The UEI has replaced DUNS numbers as the standard identifier for federal contracting within SAM.gov. Contractors must create a Login.gov account, submit entity information, and designate an E-Business Point of Contact during registration. The process typically takes 7-10 business days with annual renewals required. This standardized identifier streamlines contract management, payment processing, and facilitates compliance across all federal procurement systems. The integration enhances contractor credibility and eliminates previous data inconsistencies throughout the acquisition process.

ToggleSAM.gov Registration Process: Obtaining and Managing Your UEI

The shift from DUNS numbers to the Unique Entity Identifier (UEI) marks a significant change in federal contracting procedures. This alteration streamlines the registration requirements for entities doing business with the federal government, making the process more accessible and efficient.
To obtain a UEI, contractors must first create a Login.gov account to access SAM.gov. The registration process requires complete entity information, including the organization’s legal name, physical address, and incorporation date.
Entity validation is a critical step, ensuring all submitted information matches official records before a UEI is assigned.
After registration, which typically takes 7-10 business days, contractors must maintain their SAM status through annual renewals and timely information updates to remain eligible for federal opportunities. Organizations are required to designate an E-Business Point of Contact during the registration process. All entities must maintain an active registration status for policy renewals and transaction amendments with federal agencies like EXIM. Gathering all necessary documents beforehand can significantly reduce delays and prevent common registration errors that might require troubleshooting.
UEI Technical Integration Across Federal Procurement Systems

Since April 2022, federal contractors have navigated a thorough technical infrastructure designed around the Unique Entity Identifier (UEI) system, which now serves as the foundation for all federal procurement activities.
The UEI maintains consistent identification across multiple federal platforms, ensuring UEI accuracy throughout the acquisition process.
The Integrated Award Environment (IAE) connects essential procurement systems including FPDS, CPARS, eSRS, and FSRS, all of which now rely on the 12-character alphanumeric UEI code.
This interconnected approach eliminates the data inconsistencies previously experienced with third-party identifiers like DUNS numbers.
For contractors, this integration delivers procurement efficiency by centralizing entity information, reducing redundant data entry, and creating more transparent tracking of contract performance across federal agencies. The UEI registration process requires no associated fees unlike the previous DUNS system.
The comprehensive verification process helps ensure compliance with federal regulations while maintaining the integrity of entity data across all integrated systems.
SAM.gov serves as the central hub for this unified identification system.
Impact on Contractor Compliance and Business Operations

For contractors steering through federal procurement systems, obtaining and managing a UEI represents a fundamental compliance requirement with far-reaching operational implications.
The shift from DUNS numbers to UEI has streamlined the registration process, offering a free method to establish eligibility for federal contracts through SAM.gov.
Failure to maintain proper UEI registration can result in significant contractor penalties, including potential contract termination and loss of eligibility for future opportunities.
The UEI serves as the cornerstone for financial tracking across government systems, enabling consistent business credit profile monitoring at each physical location.
This standardized identifier facilitates seamless contract management, payment processing, and data integrity across federal procurement platforms, while simultaneously reducing administrative burdens through centralized entity management on SAM.gov. SAM registration is absolutely mandatory for all businesses seeking to participate in government contracting opportunities.
Contractors must ensure they meet eligibility criteria established in the Federal Acquisition Regulations when registering for their UEI through the SAM system.
Proper SAM.gov registration enhances contractor credibility when pursuing federal funding opportunities, positioning businesses for greater success in the competitive grant landscape.
Frequently Asked Questions
Can UEI Be Transferred Between Entities During Mergers or Acquisitions?
UEIs cannot be transferred between entities during mergers or acquisitions. Merger implications include requiring new SAM.gov registrations, while acquisition processes necessitate new UEIs for successor organizations with validated legal identity changes.
How Quickly Does SAM.Gov Assign a UEI After Initial Registration?
During the initial registration timeline, SAM.gov assigns a UEI immediately upon submission of completed registration information. The UEI assignment process occurs automatically as part of registration, though full account activation takes additional processing time.
Are International Contractors Subject to Different UEI Validation Requirements?
International contractors face similar UEI validation requirements as domestic entities. However, they may need additional steps including obtaining an NCAGE code during the validation process when registering through SAM.gov for federal contracts.
Can One Entity Maintain Multiple UEIS for Different Business Divisions?
Yes, entities can maintain multiple UEIs for different business divisions. Each physical location or division requires separate registration, as SAM.gov assigns independent UEIs per registration to maintain distinct identities for contracting purposes.
What Happens to My UEI if My SAM.Gov Registration Expires?
A UEI remains permanently assigned even after SAM.gov registration expires. However, entities become ineligible for new federal opportunities until completing the SAM.gov renewal process, though existing contracts remain valid pending contractual terms.
