Coming February 2022: Implementation of the New SAM UEI to Replace DUNS Number in NSF Systems

Effective February 28, 2022, the National Science Foundation (NSF) will begin using the new System for Award Management (SAM) issued Unique Entity Identifier (UEI) in Research.gov and Automated Acquisition Management System (AAMS). This update is being made in accordance with the government-wide transition by April 4, 2022, away from the use of the Dun & Bradstreet issued Data Universal Numbering System (DUNS) number and toward the new SAM UEI as the primary means of entity identification for Federal awards.
