Key Takeaways
- Grants.gov = find grant opportunities + submit applications
- SAM.gov = register your organization + maintain eligibility to receive federal funds
- Both are required — you cannot receive a federal grant without an active SAM.gov registration
- SAM.gov registration takes 7–10 business days at minimum — do it before you need to apply
- SAM.gov registration expires annually — you must renew every 12 months or you become ineligible
Summary
Grants.gov and SAM.gov are two separate federal systems that serve completely different purposes. The confusion between them is one of the most common mistakes first-time federal grant applicants make. Think of it this way: SAM.gov is your federal contractor/grantee license — you register once and renew annually. Grants.gov is the job board where you find and apply for specific opportunities. You need both, but they do different things.

| Registration required? | Yes — create a login.gov account | Yes — full organizational registration |
| Time to register | Minutes | 7–10 business days (often longer) |
| Annual renewal? | No | Yes — every 12 months |
| Unique Identifier | Your organization's UEI (from SAM.gov) | UEI is assigned here |
| What happens if lapsed? | Can still search; may not submit | Cannot receive federal awards |
| Cost | Free | Free (beware scam companies charging fees) |
| Managed by | HHS / Grants.gov program office | GSA (General Services Administration) |
What Is Grants.gov?
Grants.gov is the federal government's single portal for finding and applying for federal grants. All federal agencies are required to post grant opportunities (called NOFOs — Notices of Funding Opportunity) on Grants.gov. As of 2026, it lists thousands of active opportunities totaling hundreds of billions in annual federal grant funding.
On Grants.gov you can: search by agency, category, keyword, or deadline; download application packages; submit applications electronically; and track application status. You need a login.gov account to apply, and your organization's Unique Entity Identifier (UEI) from SAM.gov is required for submission.
What Is SAM.gov?
SAM.gov (System for Award Management) is the federal government's official database of vendors, grantees, and contractors. Any organization that wants to receive federal grants or contracts must be registered in SAM.gov with an active, current registration. SAM.gov replaced several older systems including CCR (Central Contractor Registration), ORCA, and FedReg.
On SAM.gov you: register your organization's legal information; receive your Unique Entity Identifier (UEI); certify eligibility representations; and maintain your registration with annual renewal. It also hosts the exclusions list (debarred organizations), entity validation, and federal contract opportunities (replacing FBO.gov).
The Correct Order of Operations
- Register in SAM.gov first — obtain your UEI and activate your registration. This takes 7–10 business days minimum; plan for 2–4 weeks if there are issues with your legal entity documentation.
- Create a Grants.gov account — link it to your organization's UEI from SAM.gov.
- Find your opportunity — search Grants.gov for NOFOs matching your organization's mission.
- Download and prepare the application package — read the NOFO completely before starting.
- Submit on Grants.gov — ensure your SAM.gov registration is still active at the time of submission.
Common Mistakes
- Waiting until you find a grant to register in SAM.gov — the 7–10 day minimum means you can miss a deadline
- Letting SAM.gov registration lapse — agencies cannot issue awards to organizations with expired SAM registrations
- Paying a company to register in SAM.gov — registration is free; scam companies charge $300–$2,000 for a service you can do yourself
- Confusing DUNS numbers with UEI — DUNS numbers were retired in 2022; Unique Entity Identifiers (UEI) replaced them in SAM.gov
- Not updating your SAM.gov profile when organizational information changes (address, banking, ownership) — outdated info can delay awards
Action Checklist
