The UEI system replaced DUNS numbers on April 4, 2022, requiring organizations to obtain Unique Entity IDs through SAM.gov for federal funding eligibility. Integration requires technical expertise to synchronize data with SAM.gov’s authentication protocols. Organizations must designate an Entity Administrator, submit verification documents, and maintain annual renewals. Implementing middleware solutions and automated compliance alerts helps maintain registration status. The thorough change demands both technical preparation and administrative diligence for continued federal participation.
Understanding the UEI Transition From DUNS to SAM.Gov

Since April 4, 2022, the federal government has implemented the Unique Entity ID (UEI) system through SAM.gov, replacing the previously used DUNS number identification system.
This significant change followed a three-day SAM.gov downtime from April 1-4, which facilitated the technical integration necessary for this alteration.
An impact analysis revealed several key benefits, including a simplified registration process that allows entities to obtain UEIs directly through SAM.gov without first securing a DUNS number.
During the implementation phase, the GSA addressed change challenges by providing automatic 60-day extensions for registrations expiring between March 18 and April 18, 2022.
The alteration eliminated DUNS numbers from federal systems, with these identifiers no longer accepted or displayed for entity registration, reporting, or searching purposes.
This change represents a government-wide shift toward streamlined entity identification processes for all federal award programs. The FCC announced that only entities receiving direct payments from the Commission must obtain a UEI and complete full entity registration in SAM.gov.
The transition to UEI has created a more unified identification system for organizations seeking federal grants and funding opportunities across all government platforms.
Registration Types and Entity Management Requirements

When preparing to engage with federal award programs, entities must understand the various registration types and requirements within the SAM.gov system. The registration process differs based on entity classification, with specific documentation needs for each category.
Businesses, non-profits, government agencies, foreign entities, and joint ventures all face unique entity verification requirements.
- Entity Administrator Designation: Each registration requires an appointed administrator who manages the SAM.gov account and oversees annual renewal processes.
- Documentation Requirements: Entities must submit official verification documents, including incorporation papers and, for foreign entities, NCAGE codes.
- Purpose Selection: Organizations must clearly indicate their registration purpose (federal contracts, grants, or other assistance) as this determines specific information requirements.
The annual renewal process guarantees continued access to federal opportunities while maintaining compliance with regulations. Entities must maintain an active registration status to qualify for policy renewals and transaction amendments with federal agencies.
Entities should prepare all required information before beginning registration to streamline the verification process and avoid potential delays. All registrants will need a 12-character UEI which replaced the previously used DUNS number system.
Understanding federal regulations is crucial for ensuring your SAM registration remains compliant through 2025 and beyond.
System Integration and Compliance Best Practices

Successful integration between internal systems and SAM.gov requires both technical expertise and regulatory awareness to maintain compliance with federal requirements. Organizations must implement regular data synchronization processes that validate entity information against SAM.gov’s records in real-time, ensuring continuous compliance with federal procurement regulations.
Effective implementation includes developing middleware solutions that properly handle SAM.gov’s authentication protocols while protecting sensitive financial data. Companies should also verify entity hierarchy integrity through SAM.gov’s public records to maintain accurate subsidiary relationships and ownership structures.
Compliance management strategies should incorporate automated compliance alerts for registration renewal deadlines, as federal regulations require annual updates to maintain eligibility for funding. Organizations can leverage SAM.gov’s notification settings to track critical deadlines and changes in registration status.
Regular system validation through quarterly audits helps identify discrepancies between internal records and federal databases, preventing potential compliance issues before they impact operations. Thorough documentation of all system integration processes is essential for SAM compliance audits to demonstrate adherence to federal requirements and avoid potential penalties that could affect government contracting eligibility.
Frequently Asked Questions
How Long Does UEI Validation Typically Take During Registration?
The UEI validation timeframe during the registration process typically varies based on several factors.
Initial document review by the Federal Service Desk usually takes 5-7 business days. For entities requiring CAGE codes or IRS verification, the process extends to 7-12 business days.
The total registration time may be longer depending on document accuracy and additional validation steps.
Entities receive email notifications about their validation status throughout the process, keeping them informed of progress or issues requiring attention.
Can Foreign Entities Obtain a UEI Without a Physical US Presence?
Yes, foreign entities can obtain a UEI without a physical US presence.
International entity eligibility for UEI registration does not require maintaining offices or operations within the United States.
However, foreign registration requirements include obtaining an NCAGE code before SAM.gov registration, providing business documentation translated to English, and having an authorized representative create a Login.gov account.
All entities receiving federal assistance must complete this process regardless of their location.
What Happens if My Entity Information Fails Validation?
When entity information fails validation, the entity faces immediate consequences. The registration or renewal will be rejected, preventing SAM.gov registration completion.
The entity verification process halts, disqualifying the organization from active solicitations and delaying UEI allocation.
To resolve issues, entities must correct discrepancies through the SAM.gov edit module, verify IRS information matches exactly, and resubmit for validation.
This process typically takes 3-5 business days to complete.
Are UEIS Transferable During Mergers or Acquisitions?
UEIs are not technically transferable during mergers or acquisitions, but they can be updated to reflect new organizational structures.
When companies merge or are acquired, UEI transferability rules require the surviving entity to update its entity information in SAM.gov rather than transferring the identifier itself.
Mergers and acquisitions implications include the need to maintain proper registration details, notify contracting officers of organizational changes, and guarantee contract continuity through the proper documentation of entity modifications.
Can I Expedite SAM.Gov Registration for Urgent Award Opportunities?
No formal expedited registration process exists for SAM.gov. For urgent funding opportunities, organizations should:
- Guarantee all documentation is complete and accurate before submission.
- Utilize pre-validation checks to catch errors early.
- Consider third-party registration assistance services.
- Contact the SAM.gov help desk for technical issues.
- Begin the process at least 10 weeks before deadlines.
- Use the UEI (assigned immediately) for preliminary award identification.
The standard timeline remains 2-8 weeks regardless of urgency.
