The term “UEI” stands for Unique Entity Identifier. It is a 12-character alphanumeric identifier assigned to entities (such as businesses, non-profits, and government organizations) that register to do business with the U.S. federal government. The UEI is used across federal agencies to track and manage awards, contracts, and grants, serving as a key component in the government’s effort to streamline procurement and award processes. It facilitates transparency, efficiency, and simplicity in the identification and management of entities engaging in transactions with the federal government. The UEI is generated and managed through the System for Award Management (, replacing the DUNS Number (Data Universal Numbering System) as the standard identifier for federal operations.
