The UEI shift, completed in April 2022, replaced DUNS numbers as the federal government’s entity identifier system. All entities conducting business with federal agencies now obtain UEIs through SAM.gov rather than from Dun & Bradstreet. Existing registrants received UEIs automatically, while new entities obtain them during SAM registration. Organizations must guarantee their UEI appears consistently across all federal documents and verify its validity through SAM.gov’s search function. The sections below explain verification processes and compliance requirements in detail.

Understanding the UEI Migration Process

When the federal government initiated the shift from DUNS Numbers to Unique Entity Identifiers (UEIs) in 2022, it marked a significant change in how organizations interact with federal systems.

The change officially concluded in April 2022, requiring all entities to obtain UEIs through SAM.gov rather than DUNS Numbers from Dun & Bradstreet.

Throughout this process, many organizations faced migration challenges related to updating their registration information and ensuring data accuracy in the new system.

Existing registrants received UEIs automatically, while new entities now obtain them during SAM registration.

Federal agencies simultaneously updated their internal systems to accept the new identifier format, developing crosswalks and validation services to maintain continuity during the change period.

The transition streamlined the process by making SAM.gov the central registration point for all federal contractors and grantees.

The U.S. Department of Education requires an active registration status in SAM.gov for institutions to maintain access to Title IV funds and other federal programs.

How to Locate and Verify Your Entity’s UEI

Following the complete implementation of the new identification system, organizations must now understand how to access and confirm their Unique Entity Identifier (UEI).

The most direct method involves logging into SAM.gov and directing to your entity registration profile, where the UEI appears under the “Unique Entity ID” section. This identifier remains accessible regardless of registration status—active, pending, or expired. The federal grant management system ensures entities can maintain continuous access to their identification details.

Access your UEI instantly in SAM.gov under “Unique Entity ID,” available regardless of registration status.

For proper UEI management, designated administrators should regularly verify that the UEI matches across all federal documentation and systems. Organizations should implement routine checks to guarantee registration details remain current, as any legal name or address changes require prompt updates in SAM.gov. Entity Administrators can easily check their registration status through the Workspace menu on SAM.gov.

The SAM.gov “Search Records” function allows quick verification of UEI validity, supporting efficient UEI updates and compliance with federal reporting requirements. Remember that the UEI replaced DUNS number as the standard federal identifier for all entities receiving federal funds as of April 4, 2022.

System Changes and Compliance Requirements for Federal Contractors

Federal contractors now face significant changes in the System for Award Management (SAM) infrastructure as the UEI shift continues to reshape federal procurement processes. The shift from CINs to UEIs represents just one of several system requirements contractors must navigate to maintain contractual eligibility. Proper SAM registration is essential for accessing government contracting opportunities.

Recent executive orders have introduced substantial compliance updates affecting federal procurement practices. Contractors must adapt to new cost efficiency initiatives while monitoring FAR clause modifications. Agency heads are required to implement centralized payment systems that demand written justification for each payment on covered contracts and grants.

The removal of certain certifications and language from the SAM system directly impacts how contracts are awarded and managed.

The consolidation of federal procurement under GSA further transforms contractor requirements. The executive order signed on March 20, 2025 requires federal agencies to shift purchasing of common goods and services to GSA. Organizations must maintain accurate SAM registration information and prepare for increased scrutiny of cost justifications to comply with transparency mandates under the Department of Government Efficiency.

Frequently Asked Questions

Can Foreign Entities Obtain a UEI for US Federal Contracting?

Yes, foreign entities can obtain a UEI for U.S. federal contracting.

The process requires foreign entity registration in SAM.gov, similar to domestic organizations. Foreign entities must first secure an NCAGE code before completing their SAM.gov registration, where they will receive their UEI.

This 12-character alphanumeric identifier is mandatory for all organizations seeking to do business with the U.S. Federal Government, regardless of their country of origin.

Federal contracting requirements apply equally to foreign and domestic participants.

Will My Entity’s Historical Data Migrate With the UEI Transition?

Yes, an entity’s historical data will migrate during the UEI shift.

The migration process was designed to preserve continuity, with GSA automatically mapping existing DUNS-based records to the new UEI system.

All historical data, including past registrations, awards, and transaction records, remains accessible through federal systems after migration.

Users did not need to take additional action, as their information was systematically updated while maintaining data integrity across integrated government platforms.

How Does UEI Affect Joint Ventures or Temporary Business Relationships?

Joint ventures and temporary business relationships must obtain their own Unique Entity ID (UEI), separate from individual partner entities. This requirement guarantees proper tracking of government contracts and transactions.

Each joint venture registers as a distinct entity in SAM with its own UEI, regardless of the temporary nature of the partnership. Partners must provide TINs or EINs during registration.

This distinct identification maintains compliance for federal contracting and helps delineate business relationships throughout the venture’s operational period.

Can Multiple UEIS Be Assigned to Different Divisions Within One Organization?

Yes, multiple UEIs can be assigned to different divisions within a single organization.

SAM.gov issues unique identifiers based on physical location and operational independence. When an organization has multiple divisions operating from distinct locations or functioning as separate business units, each can qualify for its own UEI.

Organizations should determine which division conducts business with federal agencies and use the appropriate UEI for that relationship. This approach guarantees proper tracking and compliance with federal award requirements.

What Happens if Errors Are Discovered in My Entity’s UEI Information?

If errors are discovered in an entity’s UEI information, they should be corrected promptly.

Organizations must report and fix these errors through their SAM.gov Workspace. The error correction process may require supporting documentation to validate changes in entity information.

Regular data validation helps prevent future errors and guarantees compliance with federal regulations. Maintaining accurate UEI information is essential for federal contract eligibility, proper sub-award reporting, and seamless government communication.
