UEI
Unique Entity Identifier
A 12-character alphanumeric identifier assigned by SAM.gov to uniquely identify entities doing business with the federal government, replacing the DUNS number.
What is UEI?
The UEI replaced the DUNS number as the official entity identifier for federal awards in April 2022. Unlike the DUNS number, which was assigned by Dun & Bradstreet (a private company), the UEI is generated and managed directly by SAM.gov at no cost.
You receive your UEI automatically when you register or renew your SAM.gov registration. The identifier is tied to your legal business name and physical address. If your business changes its legal name or structure, you may need to request a new UEI.
The UEI is required on all federal grant applications, contract proposals, and subaward agreements. It is used by federal agencies to track entities across the full lifecycle of federal awards.
