UEI (Unique Entity Identifier)
The Unique Entity Identifier (UEI) is a 12-character alphanumeric ID assigned to every business or organization that registers to do business with the U.S. federal government. The UEI number is managed through SAM.gov and replaced the DUNS number as the official federal identifier in April 2022.
What is a UEI Number
The UEI number meaning is simple: it is a unique code that identifies your entity in federal systems. If someone asks, “What is a UEI number?” the answer is that it is the required identifier for federal contracts, grants, and awards. Without a UEI, you cannot complete registration in SAM.gov or compete for federal opportunities.
How to Get a UEI Number
To obtain a UEI number, you must register your entity in SAM.gov. The process is free and includes submitting business information such as your legal name, address, and banking details. Once your SAM registration is active, your SAM UEI number is automatically assigned.
There is no separate fee-based process; contractors should avoid third-party sites that charge for UEI registration.
UEI Number Lookup
A UEI number lookup can be performed in SAM.gov, where entities can be searched by name or other information. Contractors often use UEI number lookup free tools provided by the government to verify vendors or check subcontractor eligibility.
For grant applicants, knowing “what is a UEI number for grants” is critical, as federal grant programs also require a valid UEI number for application submission and funding.
Where is the UEI Number Located
Your UEI number is located in your SAM.gov entity profile. If you created your account through ID.me, your UEI is still accessible in your SAM registration records. To find it, log into SAM.gov, go to your entity’s registration details, and locate the UEI field.
Why the UEI Replaced the DUNS Number
The shift from DUNS to UEI simplified the registration process by keeping all entity information within SAM.gov, eliminating the need for a third-party provider. The change also created a single, government-managed system for assigning and managing identifiers.
