The UEI (Unique Entity Identifier) is a 12-digit alphanumeric code required for all entities conducting business with the federal government. It replaced the DUNS number in April 2022 and must be obtained through SAM.gov registration. The UEI system eliminates third-party involvement, improves data accuracy, and streamlines federal procurement processes. This government-managed identifier serves as a business’s official federal ID, similar to a social security number for organizations. Further exploration reveals important registration steps and compliance requirements.
Understanding the UEI: The Federal Government’s New Entity Identifier
The Unique Entity Identifier (UEI) represents a significant change in how businesses identify themselves when working with the federal government. This 12-digit identifier has replaced the formerly used DUNS number, marking a shift to a non-proprietary system managed directly by the government rather than a third-party provider.
The UEI significance extends beyond simple identification, as it streamlines the entity verification process across all Integrated Award Environment systems.
Implemented government-wide by April 2022, the UEI serves as the standard identifier for all federal awards, grants, and contracts. Unlike its predecessor, this identifier is issued at no cost through the System for Award Management (SAM) registration process, which requires annual renewal to maintain eligibility for federal opportunities. All entities seeking federal financial assistance must obtain a UEI and register with SAM.gov to be eligible for government funding opportunities. This transition has greatly enhanced the data accuracy and overall efficiency of the federal procurement system.
How to Obtain and Maintain Your UEI Through SAM.Gov Registration
Securing a Unique Entity Identifier requires following specific procedures through the official SAM.gov platform. Organizations must first create a Login.gov account, then complete entity registration by providing legal information and administrator details. The UEI appears immediately upon successful validation. The DUNS number replacement has streamlined the federal contracting process by creating a government-owned identifier system.
| Registration Step | Potential Challenges | Solution |
|---|---|---|
| Login.gov Setup | Authentication issues | Use verified administrator email |
| Entity Information Entry | Data validation errors | Double-check all fields for accuracy |
| Identity Verification | Document submission | Prepare notarized letters in advance |
| UEI Assignment | System delays | Allow 72 hours for processing |
| Annual Renewal | Expiration oversight | Set calendar reminders for renewal process |
Regular maintenance prevents registration lapses. Organizations must update information promptly after changes and complete the renewal process annually to maintain eligibility for federal funding opportunities.
Key Benefits of the UEI System Over the Former DUNS Number Requirement
Since April 2022, the federal government has implemented a more streamlined and efficient entity identification system through the Unique Entity Identifier (UEI), replacing the long-standing DUNS number requirement.
This DUNS changeover offers numerous UEI advantages for businesses seeking federal opportunities.
The UEI system eliminates third-party dependencies by removing Dun & Bradstreet as an intermediary, automatically assigning identifiers to existing registrants. Businesses that previously had DUNS numbers will automatically receive a UEI without needing to reapply. Additionally, it removes fees previously charged for DUNS number issuance, reducing financial barriers for small businesses.
Simplified identification, zero fees, improved accessibility—UEI removes longstanding barriers for small businesses entering federal contracting.
From a compliance perspective, the UEI aligns with federal procurement modernization initiatives while centralizing entity verification under SAM.gov. The UEI serves as a business’s identifier comparable to a social security number for individuals. The transition enhances data management accuracy throughout the entire federal procurement process.
The new system also improves operational efficiency by reducing identification mismatches during submissions, shortening processing times, and synchronizing entity records across all federal procurement systems.
Frequently Asked Questions
How Long Does It Take to Receive a UEI After Applying?
UEI numbers are typically assigned immediately upon completing SAM.gov registration. The UEI application timeline is same-day when information is correctly submitted, though UEI processing delays may occur if there are issues with provided information.
Can International Organizations Obtain a UEI Number?
Yes, international organizations can obtain UEI numbers through SAM.gov. The application process is accessible to entities worldwide, with no specific restrictions on international eligibility for organizations seeking to do business with the U.S. government.
What Happens if My SAM.Gov Account Is Compromised?
If a SAM.gov account is compromised, individuals should immediately contact the Federal Service Desk to report the breach. Account security measures should be reset to prevent identity theft and unauthorized changes to registration information.
Can I Transfer My UEI to Another Business Entity?
No, UEI numbers cannot be transferred between business entities. Each legal entity must maintain its own unique identifier, as UEI ownership rights are specifically tied to the original registrant in the federal system.
Are UEI Numbers Publicly Searchable Without a SAM.Gov Account?
UEI numbers have limited public accessibility. While some basic entity information is searchable, extensive UEI data typically requires a SAM.gov account, reflecting the database privacy protections built into the federal entity identification system.
