Funding opportunities. No open Grants.gov announcements are currently indexed under CFDA 93.233 in PlainGrants.

Grant announcements can appear and close within a 30-day window, so timing matters.

Next steps. Before applying for CFDA 93.233, confirm your organization has an active SAM.gov registration and a Unique Entity ID (UEI) — these are mandatory for every federal funding instrument.
