Important Information for Proposers

Any proposal submitted in response to this funding opportunity should be submitted in accordance with the NSF Proposal & Award Policies & Procedures Guide (PAPPG) that is in effect for the relevant due date to which the proposal is being submitted. The NSF PAPPG is regularly revised and it is the responsibility of the proposer to ensure that the proposal meets the requirements specified in this solicitation and the applicable version of the PAPPG. Submitting a proposal prior to a specified deadline does not negate this requirement.

Unique Entity ID Required for Proposal Submission

July 29, 2022

On April 4, 2022, the unique entity identifier used across the federal government changed from the DUNS Number to the Unique Entity ID (UEI), generated by SAM.gov. An active SAM registration is required to submit a proposal to NSF. If the SAM registration is not complete before the proposal due date, the proposer will have to wait and submit their proposal for the next solicitation due date after SAM registration is complete. Organizations are experiencing delayed SAM.gov registrations, validations and UEI issuance. Please start SAM.gov processes early to allow for additional time. Visit sam.gov for the latest status and additional guidance.
