Use NSF Funding Search to find current opportunities, NSF Award Search to explore grants NSF has already made, and the submission system to track a proposal you have submitted. For a Grants.gov submission, check Grants.gov until NSF receives and validates it; after NSF emails you, check Research.gov. These are separate searches for separate stages.
NSF’s Funding Search has been reported temporarily unavailable; its notice directs applicants to Grants.gov and to filter by agency. If the NSF search is unavailable when you visit, use that fallback and confirm the details in the current official opportunity notice.
Find a current NSF funding opportunity
-
Open NSF Funding Search. Search for the specific research topic, then try synonyms or broader terms if the first search returns few results. Apply the directorate, division, or other filters available in the current interface.

If you are not sure which keywords to use, browse NSF’s directorate and funding pages to identify relevant areas, then return to Funding Search for a focused search.
#1 Best Overall
-
Subscribe to NSF email updates relevant to your topic to hear about new notices and updates. Treat the live opportunity notice—not an email summary or search result—as authoritative for dates, eligibility, and application requirements.
-
If Funding Search is unavailable, go to Grants.gov and filter the opportunities by agency, selecting NSF. Confirm requirements against the current official notice before deciding to apply.
NSF describes its portfolio as hundreds of funding opportunities across grants, cooperative agreements, and fellowships. That is a broad, changing count; it does not mean there is an open opportunity for every subject at any given time.

Check the notice type and schedule
NSF uses several kinds of notices. Program descriptions and announcements may remain in place longer, while solicitations generally apply for a limited period. Dear Colleague Letters can highlight topical interests or announce supplements, and Broad Agency Announcements invite proposals in some use-inspired research areas. The label alone does not tell you whether a notice is open or what it requires: check its current dates, eligibility rules, submission instructions, and any advance steps, such as a required letter of intent.
Use past awards to assess program fit
NSF Award Search is the place to examine funded projects, not open solicitations. Its database covers awards since 1989 and includes public award abstracts. Search by topic, related terms, program name, researcher, or institution; use advanced search when you know details such as the recipient organization, award number, or date range.
For program-specific results, NSF says exact program names or codes are most accurate. If you do not know the exact label, try a wildcard search or use the program lookup. You can narrow results by state or country, NSF organization, award amount, and award type. For broader analysis, the system can export up to 3,000 results in CSV, XML, Excel, or text formats.
Rank #3
Use the results to see which programs have supported related work and how award abstracts describe that work. A similar past award is not proof that a program is currently accepting proposals, that your organization is eligible, or that your proposal is likely to be funded. The database does not provide the confidential proposal documents; NSF states that it provides only award abstracts.

Proposal tracking depends on the submission route and whether NSF has received and validated the application. For an application submitted through Grants.gov, the Authorized Organizational Representative (AOR) can check its status in Grants.gov while it is still awaiting NSF receipt and validation. After NSF emails a notification, use Research.gov to check the proposal’s status.

Before NSF receipt and validation: The AOR checks the application in Grants.gov.

-
After NSF’s email notification: Check the proposal in Research.gov.

If the proposal number is missing: Follow the current NSF Proposal and Award Policies and Procedures Guide guidance and contact the NSF Help Desk. For questions about the proposal itself, contact the cognizant program officer and include the proposal number.

Do not use Award Search to check a pending application. It lists funded awards; it is not a tracker for an individual proposal’s review or decision.

NSF’s process overview says applicants have a minimum of 90 days from an opportunity announcement to prepare and submit a proposal. NSF also recommends having active SAM registration and a valid Unique Entity ID well in advance. These are general process descriptions, not a substitute for the specific solicitation or current PAPPG, which control the applicable requirements and dates.
NSF says it strives to tell applicants within six months whether proposals have been declined or recommended for funding. This is a stated goal, not a guaranteed decision date for an individual proposal. The same overview reports that principal investigators submit an average of 2.3 proposals for every award they receive and that, in 2020, 36% of new PIs received their first NSF award on their first attempt. Those agency-published figures describe broad outcomes; they do not predict an individual proposal’s result.
