Grants.gov vs SAM.gov: What's the Difference?
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.
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
Go to sam.gov and register your organization — do this today if you haven't already
Set a calendar reminder to renew SAM.gov annually — 30 days before expiration
Create an account at grants.gov using your organization's UEI
Search GrantMetric or Grants.gov for active NOFOs matching your mission
Do I need both Grants.gov and SAM.gov to apply for federal grants?
Yes. SAM.gov registration is required to be eligible for a federal award. Grants.gov is where you submit the application. You cannot receive federal grant funding without an active SAM.gov registration, even if your Grants.gov application is approved.
How do I get a Unique Entity Identifier (UEI)?
Your UEI is automatically assigned when you register your organization on SAM.gov. You don't need to apply separately — it's generated as part of the registration process. UEIs replaced DUNS numbers in April 2022.
Can individuals apply for federal grants on Grants.gov?
Most federal grants go to organizations, not individuals. However, some programs (NIH fellowship grants, NSF GRFP, some arts programs) accept individual applications. Check the NOFO's eligibility section carefully.
How long does SAM.gov registration take?
Officially 7–10 business days, but in practice it often takes 2–4 weeks, especially for new organizations or those with complex legal structures. The federal validation process with the IRS and state records can add delays. Start early.
Is there a faster alternative to Grants.gov for finding grants?
GrantMetric aggregates Grants.gov data with AI-organized sectors, faster search, and deadline alerts — making it easier to find relevant opportunities. For official applications, you still submit through Grants.gov itself.

◆ Common Questions About Federal Grants
Who is eligible to apply for federal grants?
+
Eligibility depends on the specific grant. Most federal grants are open to nonprofit organizations, universities, state and local governments, and small businesses. Some grants (like SBIR/STTR) are exclusively for small businesses, while others (like fellowships) target individuals. Always check the Funding Opportunity Announcement (FOA) for specific eligibility requirements.
How do I apply for a federal grant?
+
To apply: (1) Register in SAM.gov and obtain a UEI number, (2) Register on Grants.gov, (3) Find a relevant Funding Opportunity Announcement (FOA), (4) Prepare your application package including project narrative, budget, and required forms, (5) Submit before the deadline. Allow at least 2–4 weeks for system registrations before your first submission.
Are federal grants free money?
+
Federal grants do not need to be repaid, but they are not unconditional. Recipients must use funds only for the approved purpose, submit progress and financial reports, comply with federal regulations, and allow audits. Misuse of grant funds can result in repayment requirements and debarment from future federal funding.
How long does it take to receive a federal grant?
+
The timeline varies by agency and program. Typically, from submission to award decision takes 3–12 months. NIH review cycles run about 9 months. SBIR Phase I awards may take 5–6 months. Some emergency or formula grants move faster. Budget for at least 6 months between application and funding receipt.
What is the difference between a grant and a cooperative agreement?
+
A grant gives the recipient substantial independence to carry out the project with minimal federal involvement. A cooperative agreement involves substantial federal agency involvement in directing or participating in the project activities. Both provide funding that does not need to be repaid, but cooperative agreements require closer collaboration with the funding agency.
