Grants.govis the federal government’s single front door for finding and applying to federal grants— and that word matters. A grant is not a contract. When an agency awards a contract, it is buying a good or service for its own use, and you compete on price and capability. When an agency awards a grant, it is funding youto carry out a public purpose — research, a community program, a training initiative — and you compete on the merit of your proposed project. Different money, different rules, different application. This guide covers the grant side.
The good news is that applying through Grants.gov is free. You never pay to search opportunities or to submit an application. What you do need is patience with a two-part registration — one system for your organization, one for the people who will submit — and the discipline to start early, because the setup can take days to weeks the first time.
Grants vs. contracts: know which one you are chasing
Federal buying splits cleanly. Contracts are posted on SAM.gov and won by vendors; grants are posted on Grants.gov and won by applicants (often nonprofits, universities, state and local governments, tribes, and sometimes small businesses and individuals). The two worlds share one thing: your organization’s identity in the government’s systems. If you are still fuzzy on how that identity works, read what SAM.gov isfirst — it is the backbone of both.
A grant opportunity is published as a Notice of Funding Opportunity (NOFO), sometimes still called a Funding Opportunity Announcement (FOA). It lays out who is eligible, how much money is available, what the agency wants funded, how applications are scored, and the exact submission deadline. Read it the way you would read any solicitation — our guide on how to read an RFP applies almost directly: find the eligibility and evaluation sections before you invest a single hour.
Step 1 — Register your organization in SAM.gov
Before Grants.gov will let you apply, your organization must have an active registration in SAM.gov with a Unique Entity ID (UEI). The UEI is the government’s way of identifying your entity, and it is assigned inside SAM.gov — there is no separate place to “get” one. SAM registration is free, but it is not instant: identity validation and processing can take a while, so do this first. Our step-by-step walkthrough of how to register on SAM.gov covers the whole flow.
During SAM registration, your organization designates an E-Business Point of Contact (E-Biz POC). Remember that person — they hold the keys to who is allowed to submit grant applications on your organization’s behalf. Individuals applying for certain grants in their own name have a lighter path, but most applicants are organizations and need the full setup.
Step 2 — Create a Grants.gov account and get the right role
Next, each person who will work on applications creates their own Grants.gov account and links it to your organization by its UEI. Roles matter here. To actually submit an application, you need to be an Authorized Organization Representative (AOR). An AOR is a person your organization has authorized to submit on its behalf — and that authorization is granted by the E-Biz POC from Step 1. In practice, you request the AOR role, and your E-Biz POC approves it inside the system.
This is the single most common place first-time applicants get stuck: they build a beautiful application, then discover on deadline day that nobody has AOR authority to press submit. Sort out roles the week you decide to apply, not the week the NOFO closes. Large organizations often keep one or two standing AORs precisely to avoid this scramble.
Step 3 — Find a funding opportunity (NOFO)
Use the Grants.gov search to browse open NOFOs. You can filter by agency, eligibility, category, and funding instrument, and each opportunity carries a unique Opportunity Number and, usually, a CFDA / Assistance Listing number that identifies the program. Read the full NOFO carefully: confirm your organization type is eligible before anything else, because ineligible applicants are screened out regardless of how strong the project is.
Note the closing date and time precisely, including the time zone, and note whether the agency has any pre-application steps — a letter of intent, a required pre-registration on the agency’s own system, or a two-stage submission. Some health and science agencies, for example, route the actual application through their own systems even though the NOFO is posted on Grants.gov, so always follow the submission instructions in the NOFO itself.
Step 4 — Download the application package in Workspace
Grants.gov applications are built in Workspace, the platform’s online tool for completing and submitting an application package as a team. From the NOFO, you create a Workspace for that opportunity, which pulls in the exact set of forms the agency requires. Workspace lets multiple people fill out different forms at the same time, fill them online or download and re-upload them, and check for completeness before you submit.
Nearly every federal grant application starts with a form from the SF-424 family— the standard “Application for Federal Assistance” cover form, plus its relatives for budgets, assurances, and (for research or construction) specialized variants. The NOFO’s package tells you which SF-424 forms apply. Fill them exactly; your UEI, legal name, and address must match SAM.gov.
Step 5 — Complete the forms and narrative attachments
Beyond the standard forms, the heart of most grant applications is the project narrative: your statement of need, project design, goals and measurable outcomes, timeline, organizational capacity, and a detailed budget with a budget justification. These are usually uploaded as attachments in the format the NOFO specifies — often PDF, frequently with page limits, font, and margin rules that agencies do enforce. An over-length or wrong-format narrative can be rejected unread.
Map your attachments to exactly what the NOFO’s evaluation criteria reward. If reviewers score “project design” on a 30-point scale, make your project-design section obvious and complete. Grant reviewers work from a scoring rubric, so writing to that rubric is the whole game.
Step 6 — Submit through Workspace before the deadline
When the package is complete, the AOR submits it directly from Workspace. Grants.gov runs validation checks and then issues a series of confirmations: a submission receipt, then a validation result, and finally an indication that the receiving agency has retrieved your application. Watch for all of these — a “Received” status is not the same as “Validated,” and a validation error you ignore means you did not actually apply.
Two habits protect you. First, submit early — hours before the deadline, not minutes. If validation rejects your package for a fixable error, you want time to correct and resubmit before the clock runs out. Second, treat the posted deadline in its stated time zone as final; Grants.gov timestamps submission at the moment it is received, and late is late. There is no email workaround.
Costs, and what happens after you apply
Applying costs nothing. After submission, the agency — not Grants.gov — reviews applications, typically through a merit or peer review against the published criteria, which can take months. You may be asked for clarifications or additional information. Award decisions come from the agency directly, and unsuccessful applicants can usually request reviewer feedback, which is gold for your next attempt.
The bottom line
Grants.gov is federal grantmoney, not contracts — a different competition with a different application, but the same identity backbone. Win by getting the plumbing right early: an active SAM.gov registration with a UEI, a Grants.gov account, and a person with AOR authority approved by your E-Biz POC. Then find a NOFO you are truly eligible for, build the package in Workspace with a narrative written to the scoring rubric, and submit with hours to spare. If contracts turn out to be a better fit for what you do, start with the SAM.gov guide instead, or browse open bids near you to see what agencies are buying right now.
