How to apply: step by step
- Register on SAM.gov. Every federal grant applicant needs an active SAM (System for Award Management) registration. Allow 2-4 weeks for new registrations to process. Existing registrations must be renewed annually.
- Get a UEI number. Your Unique Entity Identifier is assigned through SAM.gov and replaces the old DUNS number. You will need this on every federal application.
- Review the Notice of Funding Opportunity (NOFO). Download the full NOFO from Grants.gov. Pay close attention to review criteria, budget limits, and required attachments.
- Prepare your application package. Most federal grants require a project narrative, budget justification, organizational capacity statement, and supporting documents. Follow the page limits and formatting rules exactly.
- Submit through Grants.gov. Create a workspace, upload all required forms and attachments, and submit before the Varies by FOA (Multiple Per Year) deadline. The system timestamps your submission, and late applications are automatically rejected.
- Confirm receipt. You will receive a tracking number and confirmation email. Check back in 1-2 business days to verify your application passed the Grants.gov validation checks.
