SAM.gov Registration Guide: Federal Grant Prerequisites 2026
Key Takeaways
SAM.gov is free — any service charging you to register is a scam
Allow 10–15 business days — never start registration less than 2 weeks before a deadline
UEI replaced DUNS numbers in April 2022 — UEI is assigned by SAM.gov at no cost
Registration expires every 365 days — a lapsed registration blocks payments even on active grants
After SAM.gov: you still need Grants.gov + agency-specific systems (eRA Commons, Research.gov)
Why SAM.gov Is Non-Negotiable
The System for Award Management (SAM.gov) is the federal government's primary database for entities doing business with the government. An active SAM.gov registration is a prerequisite for receiving any federal grant or contract. Without it, your application will be rejected at the administrative review stage — regardless of technical merit. Registration is free; any third party charging for this service is operating fraudulently.
1. What You Need Before You Start
EIN (Employer Identification Number) — Issued by the IRS. Required for all organizations. Must match IRS records exactly — discrepancies cause validation delays of up to 5 business days.
Legal business name and address — Must match IRS records exactly.
NAICS codes — North American Industry Classification System codes describing your primary business activities.
Banking information — ABA routing number and account number for electronic funds transfer (EFT).
Login.gov account — SAM.gov uses Login.gov for identity verification. Create this first at login.gov.
2. The UEI — Replacing DUNS Numbers
As of April 2022, the federal government replaced DUNS numbers with the Unique Entity Identifier (UEI), assigned directly by SAM.gov at no cost. If your organization was previously registered in SAM.gov using a DUNS number, your UEI was automatically assigned and is visible in your entity record. New registrants receive their UEI upon completing entity registration. The UEI must appear on all federal grant applications.

SAM.gov Entity Validation Timeline 2026
The SAM.gov entity validation timeline in 2026 depends heavily on IRS EIN matching. When you submit a new entity registration, SAM.gov sends your Employer Identification Number (EIN) and legal entity name to the IRS for real-time validation. If your name exactly matches IRS records, validation completes in minutes and the registration proceeds. Mismatches — common when a business uses a trade name instead of its legal IRS name, or when the address differs from IRS records — trigger a manual review queue that can add 10–15 business days. To avoid delays: use your exact legal name as it appears on your IRS EIN assignment letter, ensure your physical address matches IRS records, and submit at least 3 weeks before any grant deadline. If your registration is stuck in validation, contact the SAM.gov Federal Service Desk (FSD) at fsd.gov with your case number — federal contractors and grant applicants can request expedited review when a grant deadline is imminent.
4. Annual Renewal Is Mandatory
SAM.gov registrations expire after 365 days and must be renewed annually to remain active. A lapsed registration prevents receiving award payments — even on existing, active grants. Grants.gov and agency systems block applications from entities with expired SAM.gov records. Set a calendar reminder 60 days before your registration expiration date (visible in your SAM.gov entity record).
5. After SAM.gov: Additional System Registrations
SAM.gov is the foundation, but most agencies require additional registrations:
Grants.gov — Required for all federal grant submissions. Register the organization as an AOR (Authorized Organization Representative). Links to SAM.gov via UEI.
eRA Commons — Required for all NIH grants and many other DHHS awards. Institutional registration must precede individual PI registration.
Research.gov — Required for NSF submissions. Create account and link to institution before your target deadline.
Proposal Central — Used by NIH for some fellowship mechanisms and several private foundations.

Frequently Asked Questions
How long does SAM.gov registration take?
Allow 10–15 business days before any grant deadline. Many registrations complete in 2–3 days for straightforward entities, but delays occur when IRS EIN validation fails or the entity is flagged for manual review. Never start SAM.gov registration less than 2 weeks before a deadline.
Is SAM.gov registration free?
Yes. SAM.gov registration is completely free. Any third party charging a fee to register you in SAM.gov is not operating officially. Go directly to sam.gov to register at no cost.
What is a UEI number?
The Unique Entity Identifier (UEI) replaced DUNS numbers in April 2022. It is assigned directly by SAM.gov at no cost. If you previously had a DUNS number, your UEI was automatically assigned. It must appear on all federal grant applications.
How often do I need to renew SAM.gov registration?
Every 365 days. A lapsed registration prevents receiving award payments even on existing, active grants. Set a calendar reminder 60 days before your registration's expiration date, visible in your SAM.gov entity record.
Can I apply for federal grants without SAM.gov registration?
No. An active SAM.gov registration is a mandatory prerequisite for all federal grants. Applications from entities without active registrations are rejected at the administrative review stage regardless of technical merit.

◆ 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.
