What Is SAM.gov and Why Do You Need It?
SAM.gov — the System for Award Management — is the federal government's centralized database for all contractor registration. It is run by the General Services Administration (GSA) and used by every federal agency to verify that businesses are authorized to receive contract awards.
Without an active SAM.gov registration, two things happen: (1) you cannot submit proposals on federal contracts above the micro-purchase threshold ($10,000), and (2) even if you somehow bid without it, a contracting officer cannot legally award you a contract. The registration is a hard legal prerequisite — there are no workarounds.
Beyond basic eligibility, your SAM.gov registration determines how federal agencies see your business: your NAICS codes tell them what you do; your set-aside certifications tell them who you are; your point of contact tells them who to call. Every piece of data in your profile either helps you get found or works against you.
The common misconception is that SAM.gov registration is complicated or requires special expertise. It does not. The process is straightforward — what causes delays is skipping the document preparation step and rushing through fields that require exact formatting. If you prepare before you start, the registration itself takes 2–3 hours of work.
Start here: SAM.gov uses login.gov for authentication. Create your login.gov account before you go to SAM.gov — this one step alone prevents the most common first-time registration delays.
Before You Start: The Documents You Need
You cannot complete SAM.gov registration in one sitting if you do not have your documents ready. Gather these first. Every item on this list is required — missing one mid-registration will stall you until you find it.
Your federal tax ID from the IRS. Apply free at irs.gov in under 5 minutes and receive it immediately. This must be active — SAM.gov validates it against IRS records.
This is the single most important field in SAM.gov. If your IRS name says "Acme LLC" and you enter "Acme L.L.C." with extra periods, it will fail the IRS TIN match check and add days to your timeline. Pull out your EIN letter or IRS confirmation email before you start.
A P.O. Box will not work for the entity address field. SAM.gov requires a physical location for the business. You can add a separate mailing address if needed, but the primary address must be a real street address.
You receive this automatically during registration — SAM.gov assigns it, you do not apply for it. You do not need a DUNS number (DUNS was retired in 2022).
6-digit industry classification codes. Your primary NAICS code determines your set-aside eligibility. Find yours at census.gov/naics or naics.com. You need at least one, and you can list up to 15. Choose carefully — wrong codes mean you miss relevant set-aside opportunities.
Routing number and account number for direct deposit payments. The government pays by ACH — you must have a US business bank account. Personal accounts do not work.
Name, email address, and phone number for the person who will receive SAM.gov communications and contract officer outreach. This can be the business owner.
Get your NAICS codes right before you start. Your primary NAICS code determines your eligibility for set-aside contracts. If you are not sure which codes apply to your business, spend 15 minutes researching at census.gov/naics before you open SAM.gov. A wrong primary code is the second most common registration mistake after name mismatches.
Create Your login.gov Account
SAM.gov uses login.gov for all authentication. This means you do not create a username and password on SAM.gov itself — you create an account at login.gov, and SAM.gov trusts that account. This is a change from the old SAM.gov system which had its own credential management.
Go to secure.login.gov/sign_up/enter_email and create an account using your business email address. Do not use a personal email if you are registering a business — contracting officers will see the email on your profile, and a business contact on a personal email looks unprofessional.
Two-Factor Authentication (Required)
Login.gov requires two-factor authentication (2FA). You have three options:
Authenticator App (Recommended)
Use Google Authenticator, Authy, or 1Password. Generate a TOTP code each time you sign in. Most reliable option — no SMS delivery risk.
SMS / Text Message
Receive a one-time code via text. Works but depends on cell signal. Less reliable if you travel or have poor reception.
Backup Codes
One-time use codes to keep in a safe place. Use these if you lose access to your primary 2FA device. Print them out and store them securely.
Once your login.gov account is active and 2FA is set up, go to sam.gov. Click Sign In, then select Create an Account. SAM.gov will redirect you to login.gov — enter the credentials you just created, complete the 2FA challenge, and you are in.
Start Your Entity Registration on SAM.gov
Once signed in, navigate: My SAM → My Registrations → Register New Entity.
On the first screen, you are asked about your purpose for registering. Select: "I want to be able to bid on federal contracts." This is the option that creates the full contractor profile and enables your business to receive contract awards.
The registration wizard has approximately 12 sections. The key thing to know: the browser does not always auto-save. You must explicitly click the Save button on each section before closing the browser, navigating away, or refreshing the page. Partial saves are supported — work through one section, save it, move to the next. Never work through multiple sections in one session without saving.
Use Chrome or Firefox — Safari and Edge have been reported to drop session data in some SAM.gov workflows. If your session expires mid-registration, you will not lose your progress if you have been saving as you go.
Core Data — Entering Your Business Identity
This is where most first-time registrations go wrong — and it is almost always the business name field.
The IRS TIN Match Check
When you enter your EIN and legal business name, SAM.gov sends an automated request to the IRS for verification. The IRS checks that the name on your SAM.gov registration matches the name associated with your EIN in their records — character for character, including punctuation and spacing.
The most common rejection cause: "Acme LLC" in IRS records versus "Acme L.L.C." or "Acme LLC." entered on SAM.gov. If you do not know exactly how your business name appears on your EIN letter, call the IRS at 800-829-4933 before you start. They will tell you exactly what name is on file.
Address Requirements
The physical address field requires a real street address — not a P.O. Box, not a virtual office address, not a registered agent address. SAM.gov will accept it if you enter it, but a contracting officer who sends a contracting officer representative to verify your business location will show up at a P.O. Box and mark you as non-responsive. Use your actual operating address.
After submitting Core Data, the IRS TIN match check begins. This takes 1–2 business days. SAM.gov will email you when the check completes — either a pass notification or a rejection with the exact discrepancy you need to fix.
Assertions — NAICS Codes, Size, and Certifications
The Assertions section is where SAM.gov records what your business does and who it is. This data determines which set-aside opportunities you can access and how agencies categorize your profile.
NAICS Codes
Select every NAICS code that describes a service or product line your business provides. You can list up to 15. Your primary NAICS code is the one that generates the most revenue — this is the code that determines your size standard eligibility for set-asides.
To find your codes: use the search tool at census.gov/naics. Search for your industry keyword and note the 6-digit codes. If your service spans multiple categories, list the codes for each one — this widens your opportunity reach without limiting you.
Size Certifications
Check every size and certification category that applies to your business. These are self-certifications — the federal government trusts that you have determined your eligibility accurately. False certifications constitute federal fraud.
Small Business (SB)
Under 500 employees (or applicable revenue threshold for your NAICS). Most small businesses qualify automatically. No separate application — just self-certify in SAM.gov.
Women-Owned Small Business (WOSB)
At least 51% women-owned and controlled. Apply through SBA's certify.sba.gov portal. EDWOSB certification opens additional restricted competitions.
Service-Disabled Veteran-Owned (SDVOSB)
51%+ owned by service-disabled veterans. Self-certified in SAM.gov; VA requires separate verification for VA set-aside contracts.
8(a) Business Development
For socially and economically disadvantaged businesses. Requires SBA application and certification — not self-certifiable. Note application status in SAM.gov if in progress.
HUBZone
Business located in a HUBZone census tract. Requires SBA HUBZone certification — not self-certifiable. Check eligibility at sba.gov/hubzone.
EconomicALLY Disadvantaged (EDWOSB)
Subset of WOSB for businesses meeting additional economic disadvantage criteria. Opens more restricted competition categories. Certified through SBA.
Size standards are NAICS-specific. A 300-person business can be small under one NAICS code and large under another. Every solicitation specifies the applicable NAICS code and its size standard. Check your status per solicitation — do not rely solely on the certification you entered in SAM.gov.
Points of Contact and Representations & Certifications
The Points of Contact section asks for the people who represent your business in different contexts. For a small business, the same person can appear in multiple contact roles — usually the owner or a senior employee.
Government Business POC
The primary contact for government correspondence. This person's name, email, and phone appear on your public SAM.gov profile. Use a business email — not a personal one — and a phone number you actually answer.
Electronic Business Point of Contact
The person who receives system-generated notifications — solicitation alerts, amendment notices, award notifications. Usually the same person as the Government Business POC.
Past Performance POC
The person who can discuss your company's past contract performance if a contracting officer evaluates your proposal. For new businesses without federal past performance, this can be a commercial reference who can speak to your work quality.
Representations and Certifications (Reps & Certs)
The Reps & Certs section is a legal attestation of your business information. Each question asks about specific conditions — size, ownership structure, foreign involvement, past performance history, and various regulatory compliance requirements. Answer every question accurately. The federal government can void a contract if a contractor's representations are found to be false at time of award.
Most questions are straightforward yes/no answers. If a question does not apply to your business, you usually answer "No" — not leave it blank. Read each question and its context before answering.
Submit and Wait for Activation
Once all sections show a green checkmark, you can hit Submit. You will receive a confirmation email with a case number — save this email. Your case number is how you track your registration status and communicate with the SAM.gov help desk if something goes wrong.
After submission, you are in a waiting state:
Set a calendar reminder now: SAM.gov registrations expire annually. Add a reminder 60 days before your registration anniversary date. Renewal takes less time than initial registration — but only if you do it before it expires. An expired registration while you are mid-bid is a nightmare scenario.
The 7 Mistakes That Kill SAM.gov Registrations
These are the most common reasons registrations fail, get rejected, or take three times longer than they should. Avoid every one of them.
What to Do After Your SAM.gov Registration Goes Active
Your SAM.gov registration being active is the starting line — not the finish line. Being registered does not automatically put you in front of contracting opportunities. Here is what the registration enables and what you need to do next.
What Your Active SAM.gov Registration Enables
Bid on federal contracts above $10,000
Your SAM.gov registration is the legal prerequisite for contract awards. Without it, your proposals are rejected before they are read.
Receive contract awards and get paid by federal agencies
Agencies pay through EFT to the bank account you entered in SAM.gov. If your bank account information changes, update it in SAM.gov before your next payment cycle.
Access set-aside contract opportunities
If you certified for WOSB, SDVOSB, HUBZone, or 8(a), your SAM.gov profile unlocks restricted competition opportunities where large firms cannot bid.
Be found by contracting officers searching SAM.gov for vendors in your NAICS codes
COs use SAM.gov to search for vendors before issuing Sources Sought notices and small business set-asides. Your profile is your public contracting resume.
The Next Step: Find Contracts You Can Actually Win
Now that you are registered, the hard part begins: finding and winning the right contracts. SAM.gov lists every opportunity — but sorting through thousands of listings to find the ones that fit your NAICS codes, certifications, and size standard is a full-time job.

Frequently Asked Questions
Yes. SAM.gov registration is completely free. The federal government operates the System for Award Management and does not charge for entity registration. If a company offers to "register you on SAM.gov" for a fee — especially $200 to $2,000 — it is a scam. The official site is sam.gov. Anyone charging you to use it is reselling a free government service.
Most small businesses complete SAM.gov registration in 7–14 business days from start to active status. The IRS TIN match validation step alone takes 1–2 business days and cannot be expedited. Some registrations take up to 3 weeks if IRS records need correction or additional review is triggered. Plan accordingly — you cannot bid on contracts while registration is pending.
No. SAM.gov replaced DUNS numbers with the Unique Entity Identifier (UEI) in April 2022. The UEI is assigned automatically during the SAM.gov registration process — you do not need to apply for one separately or pay for a DUNS number. If a vendor tells you that you need to "get a DUNS number first," they are either behind on current requirements or trying to charge you for something you can get for free.
When you enter your EIN on SAM.gov, the system sends your legal business name and EIN to the IRS for verification. The IRS checks that the name on your SAM.gov registration exactly matches the name on file with the IRS. If there is any mismatch — even a missing period in "LLC" vs "L.L.C." — the validation fails and you receive a rejection email explaining the discrepancy. Fixing the mismatch and resubmitting can add another 1–5 business days to your timeline.
SAM.gov entity registrations expire every year on the anniversary of your initial submission date. You must log in and renew before it expires — an expired registration means you cannot receive contract awards or get paid on existing contracts. Set a reminder 60 days before your expiration date to give yourself time to complete the renewal process before it goes inactive.
Yes. SAM.gov registration does not require past performance or a track record. You need an EIN (which you can get from the IRS in minutes at irs.gov), a legal business name, a physical address, and a US bank account. Brand-new LLCs and sole proprietorships regularly register on SAM.gov and win contracts within their first year of operation.
beta.SAM.gov is the newer, redesigned interface for SAM.gov. As of 2026, most entity registration functions have migrated to beta.SAM.gov. The legacy sam.gov domain still exists and redirects to beta.SAM.gov for most functions. When searching for contract opportunities, use beta.sam.gov for the full opportunity search and filtering tools. Entity registration is completed in the newer interface.
