UEI Lookup
Search any SAM.gov Unique Entity ID (UEI), company name, or CAGE code and see the entity's registration status, expiration, NAICS codes, and location — the identifier that replaced DUNS, made searchable.
The UEI, explained
The Unique Entity ID is the 12-character code SAM.gov assigns to every registered organization. Since April 4, 2022 it is the single authoritative way the U.S. government identifies an entity across contracting, grants, and payment systems — the role the DUNS number used to play. If you are matching a supplier record between systems, the UEI is the key that never collides.
Knowing an entity's UEI is only the start. What a procurement or supplier-quality team actually needs to know is whether that registration is active, when it expires (SAM registrations lapse every 12 months if not renewed), and how the entity is classified by NAICS. This lookup returns all of it from a single search, so a UEI becomes an answer instead of another lookup.
Every result opens a full evidence profile: legal name, UEI, CAGE code, plain-English SAM status, an "expires in N days" badge, the primary and secondary NAICS classifications with their meanings, and the registered location — with a cross-link to the machine-shop profile when we host one.
Frequently asked questions
- What is a UEI (Unique Entity ID)?
- The Unique Entity ID (UEI) is a 12-character alphanumeric identifier assigned to an entity when it registers in SAM.gov. It uniquely identifies an organization across all federal systems and is required to bid on and receive federal awards.
- Did the UEI replace the DUNS number?
- Yes. On April 4, 2022, the federal government stopped using the Dun & Bradstreet DUNS number and adopted the SAM-generated UEI as the authoritative entity identifier. Entities that had a DUNS number were assigned a UEI automatically; new registrants receive a UEI directly from SAM.gov at no cost.
- How do I find an entity's UEI for free?
- Enter the company name, its 12-character UEI, or its 5-character CAGE code in the search box above. Each result shows the entity's UEI alongside its SAM.gov registration status, expiration date, primary NAICS, and location. Click through for the full profile.
- What is the difference between a UEI and a CAGE code?
- The UEI is the primary SAM.gov identifier that replaced DUNS and is used across all federal award systems. The CAGE code is a separate five-character code assigned by the Defense Logistics Agency for logistics and contracting. An active registrant typically has both, and this tool shows them together.
- Where does this UEI data come from?
- From the public-domain SAM.gov monthly entity extract dated July 5, 2026. It is a point-in-time snapshot; confirm the live record at SAM.gov before relying on it for a contract action.
