To apply for a UEI through SAM.gov, users must first create a Login.gov account with two-factor authentication. Next, they should register their entity on SAM.gov, providing accurate business information and required documentation. The system validates this information, which typically takes 3-5 business days. Upon successful validation, SAM.gov issues a 12-character UEI. Scheduling renewals 60 days in advance helps avoid disruptions in federal contracting eligibility. The following guide addresses common registration challenges businesses encounter.

ToggleWhat Is the UEI and Why Your Organization Needs One

The Unique Entity Identifier (UEI) represents a critical component in the federal funding landscape, serving as a 12-digit government-issued number that has fully replaced the previous DUNS system. Mandated under 2 CFR Part 25, this identifier is required for all entities seeking federal contracts, grants, or loans.
The importance of UEI extends beyond mere compliance, as it offers significant operational benefits. Organizations gain streamlined access to federal opportunities through a simplified, centralized registration process on SAM.gov. All UEIs are issued exclusively through SAM.gov as the official government website for entity registration. Companies must verify eligibility carefully before beginning the application process to ensure they meet all requirements.
UEI benefits include reduced administrative burden, elimination of third-party fees previously required by Dun & Bradstreet, and improved data accuracy through direct government validation. Additionally, the system enhances transparency by enabling public tracking of federal fund recipients via USAspending.gov. The UEI serves as a federal marketplace gateway for businesses looking to participate in GSA and SBA programs, determining eligibility for various government contracting opportunities.
Step-by-Step Guide to Obtaining Your UEI on SAM.gov

Maneuvering the UEI application process through SAM.gov requires careful preparation and attention to detail, but organizations can successfully complete this essential registration by following a structured approach. The process begins with account setup and proceeds through entity validation. It’s important to remember that SAM.gov is entirely free and users should be wary of websites requesting payment for UEI registration services. Maintaining accurate information throughout the registration process is crucial for compliance with federal regulations and successful interactions with government agencies.
Registration Phase | Key Requirements | Estimated Timeline |
---|---|---|
Account Setup | Login.gov account, business documentation | 1-2 days |
Entity Validation | Legal business details, supporting documents | 3-5 days |
Post-Registration | Annual renewal, system integration | Ongoing |
Organizations must first create a Login.gov account with two-factor authentication before entering their legal business information. After submitting documentation, SAM.gov validates the entity against public records. The system utilizes an Entity Validation Service to verify your organization’s information against official records. Once validated, the system generates a 12-character UEI, which remains active for one year and must be renewed annually.
Common Challenges and Solutions When Registering for a UEI

Despite careful preparation, organizations frequently encounter obstacles during the UEI registration process that can delay or prevent successful completion.
Entity validation can take up to 10 business days, with name changes or mergers triggering additional verification steps.
Common registration hurdles include system timeouts that erase unsaved progress, browser compatibility issues, and multi-factor authentication failures requiring help desk intervention.
Documentation errors such as expired tax IDs, mismatched legal names between IRS records and SAM.gov entries, and incomplete banking details often block validation. Entities using unregistered “DBA” names experience significant validation challenges due to stricter documentation requirements. Ensuring accurate NAICS code alignment with your PSC codes is essential for proper categorization and avoiding missed government contracting opportunities.
To overcome these challenges, organizations should pre-validate entity data using IRS records, bookmark SAM.gov’s status checker, contact the Federal Service Desk for technical issues, and schedule renewals 60 days early to avoid processing delays.
Frequently Asked Questions
Can I Transfer My UEI if My Organization Changes Legal Structure?
No, UEI numbers cannot be transferred when an organization changes its legal structure. The entity must obtain a new UEI by completing a fresh SAM.gov registration that reflects the updated legal structure.
How Do Joint Ventures Obtain a Single UEI Number?
Joint ventures obtain a single UEI by registering as a partnership through SAM.gov, providing all partners’ TINs/EINs, submitting partnership agreements, and selecting “Joint Venture” during the application process. Joint venture requirements include valid partner documentation.
What Happens to My UEI if My Organization Relocates Internationally?
When an organization relocates internationally, their UEI number remains unchanged as it’s tied to the entity itself. The relocation impact requires updating SAM.gov registration with new address details to maintain international compliance.
Are Tribal Governments Subject to Different UEI Registration Requirements?
Tribal governments follow the same UEI registration process as other entities despite their tribal sovereignty status. They must obtain UEIs through SAM.gov using identical procedures, though specialized assistance is available through the Federal Service Desk.
Can Multiple Departments Within One Organization Use the Same UEI?
Multiple departments within a single organization can use a shared UEI if operating from the same physical location. Different locations may require separate UEIs depending on specific departmental needs and operational structure.
