S-STEM: SAM Unique Entity Identifiers and S-STEM deadlines

February 28, 2023

Effective February 28, 2022, the National Science Foundation (NSF) began using the new System for Award Management (SAM) issued Unique Entity Identifier (UEI) in Research.gov. This update was made in accordance with the government-wide transition on April 4, 2022, away from the use of the DUNS number and toward the new SAM UEI as the primary means of entity identification for Federal awards. The Proposal and Award Policies and Procedures Guide (PAPPG) document requires institutions to have a SAM.GOV UEI in order to submit proposals. Institutions not ready to submit by the proposal submission deadline will need to wait until next year's cycle. Please refer to the guidance in the PAPPG: https://beta.nsf.gov/policies/pappg/23-1/ch-1-pre-submission#1G2
