The Unique Entity ID system streamlines federal procurement by eliminating third-party involvement and centralizing entity validation through SAM.gov. This 12-character alphanumeric system, implemented in April 2022, provides free registration and automated validation processes for businesses seeking government contracts. Organizations now experience reduced administrative burdens, lower costs, and improved data accuracy in federal contracting. The modernized system enables transparent access to documentation and strengthens compliance management, setting the foundation for deeper understanding of federal procurement processes.
Breaking Down the UEI Transition: What Business Owners Need to Know

Since the federal government’s implementation of the Unique Entity ID (UEI) system in April 2022, business owners have needed to adapt to significant changes in federal procurement processes.
The shift from DUNS to UEI has streamlined entity validation by eliminating third-party involvement and centralizing the process within SAM.gov. During the transition, SAM.gov was offline from April 1 to April 4 while systems were updated.
Business owners must now complete their entity validation directly through SAM.gov to obtain a UEI, which consists of a 12-character alphanumeric code.
Organizations previously registered with DUNS numbers received automatic UEI assignments during the shift, while new businesses must register through SAM.gov’s integrated system.
To maintain compliance, business owners should regularly update their SAM.gov information and use their UEI for all federal contract submissions, grant applications, and related documentation. The UEI remains valid indefinitely and does not require renewal, though annual SAM registration updates are still necessary.
Key Benefits of the New Federal Identification System

The implementation of the Unique Entity ID system brings substantial advantages to federal procurement operations, marking a notable improvement in government contracting processes.
The centralized system in SAM.gov eliminates third-party fees, reduces administrative burdens, and streamlines entity registration through automated UEI assignment. The new 12-character alphanumeric code ensures standardized identification across all federal systems.
SAM.gov’s centralized UEI system offers cost-free registration and reduced paperwork, making federal contracting more accessible and efficient for businesses.
The new system enhances data accuracy through real-time updates and automated validation, while providing transparent access to critical documentation.
Small businesses and nonprofits benefit from free registration and simplified procedures, removing financial barriers to federal contracting opportunities.
Additionally, the UEI system strengthens compliance management through consistent validation processes and timely notifications.
The non-proprietary nature of the system supports scalability and future technological integration, positioning federal procurement for continued modernization and efficiency improvements.
Frequently Asked Questions
How Long Does It Take to Receive a UEI After Registering?
After registering on SAM.gov, entities typically receive their UEI immediately upon submission, but full activation takes 7-10 business days.
This timeframe allows for necessary validations, including IRS verification and CAGE code processing.
Delays may occur if manual review is required or if information needs correction.
Organizations seeking “All Awards” registration may experience longer processing times due to additional verification requirements.
Can International Entities Obtain a UEI for Federal Contracting Opportunities?
Yes, international entities can obtain a UEI through SAM.gov registration for U.S. federal contracting opportunities.
The process requires international organizations to first secure an NCAGE code, then complete SAM.gov registration with proper documentation and certifications.
International registrants must provide proof of authorization, legal business information, and English translations of documents when necessary.
Once validated, the entity receives a permanent UEI, enabling participation in federal procurement activities.
What Happens to My Existing DUNS Number During the Transition?
During the shift, existing DUNS numbers remain in SAM.gov for historical reference but are no longer active for federal procurement processes.
The system automatically assigns a new UEI to each entity’s SAM.gov registration. While DUNS numbers may temporarily appear in legacy systems, they have been replaced by UEIs as the primary identifier.
Organizations should update their internal systems and documentation to reflect this change, ensuring compatibility with the new UEI system.
How Often Must UEI Information Be Updated in SAM.Gov?
UEI information in SAM.gov requires annual updates to maintain active registration status.
Organizations must verify and renew their information at least once every 12 months. However, certain changes require immediate updates outside the annual cycle, including modifications to legal business name, organizational address, or ownership structure.
To prevent registration lapses, entities should initiate the renewal process up to 60 days before expiration dates.
Failure to update can disrupt federal contract eligibility.
Are UEIS Transferable When a Business Is Sold or Acquired?
UEIs are not transferable between separate legal entities during a business sale or acquisition.
The UEI remains with the original registered business entity, regardless of ownership changes.
When a business is sold, the existing UEI stays with that business structure, provided it maintains the same legal entity status.
However, if the sale results in creating a new legal entity, that new entity must obtain its own UEI through SAM.gov registration.
