SAM.gov is the starting line for every government contractor
If you want to do business with the federal government — sell products, provide services, or bid on any contract above $25,000 — your business must be registered in SAM.gov. There is no workaround, no exception, and no alternative registry. SAM.gov is the System for Award Management, and it is the single official source the federal government uses to verify that a business exists, is legally eligible to receive payments, and meets basic compliance requirements.
Registration is completely free. Despite what some third-party websites will tell you, you do not need to pay anyone to register in SAM.gov. Any website charging a fee to register your business with the government is a private intermediary selling a service you do not need. Go directly to sam.gov and register yourself.
What SAM.gov actually does
SAM.gov serves multiple functions in the federal procurement ecosystem. Understanding all of them helps you use the system correctly:
- Entity registration: The core function. Your business registration makes you eligible to receive federal contracts and grants.
- Opportunities search: All federal contract solicitations above $25,000 are posted here. This is the database the Hidden Handbook Contract Finder pulls from.
- Exclusions database: SAM.gov maintains a list of individuals and businesses banned from receiving federal awards due to fraud, non-performance, or other violations. Agencies check this before making any award.
- Wage determinations: For service contracts, SAM.gov hosts wage determinations under the Service Contract Act — the minimum wages you must pay workers on federal service contracts.
- Assistance listings: Formerly the CFDA (Catalog of Federal Domestic Assistance), this section lists federal grant programs.
What you need before you start
Gather these before you begin. Having them ready prevents the registration from stalling partway through:
- Employer Identification Number (EIN): Also called a Federal Tax ID. If you are a sole proprietor without employees, you can use your Social Security Number, but an EIN is strongly recommended for privacy and professionalism. Get one free at irs.gov in minutes.
- Legal business name and address: Must match your IRS records exactly. Discrepancies cause registration failures and can delay you by weeks.
- NAICS code: Your primary North American Industry Classification System code. Use census.gov/naics to look up the right code for your business activity.
- Bank account information: Routing number and account number for electronic funds transfer. This is how the government pays you — they do not cut paper checks for contract payments.
- Unique Entity Identifier (UEI): SAM.gov assigns a UEI to every registered entity. If you have never registered before, SAM.gov will assign one during registration.
The registration process, step by step
Step 1 — Create a login.gov account. SAM.gov uses login.gov for identity verification. Go to login.gov and create an account with your email address. You will need to verify your identity — have your state-issued ID or passport ready before you begin.
Step 2 — Navigate to SAM.gov and start a new registration. Once logged in, go to sam.gov and select Register Entity. Choose Business or Organization as your entity type.
Step 3 — Enter your core data. This section collects your legal business name, physical address, EIN, and business start date. Double-check that everything matches your IRS records exactly, including punctuation and abbreviations.
Step 4 — Assign your NAICS codes. Enter your primary NAICS code and any additional codes that describe your business activities. You can add multiple codes — add all that apply to work you actually perform.
Step 5 — Complete the assertions. This section asks about your business size to determine small business eligibility, ownership for set-aside certifications, and whether you are subject to various federal requirements. Answer accurately — these assertions affect which contracts you can bid on.
Step 6 — Enter your representations and certifications. This is the longest section. It covers compliance certifications required by the Federal Acquisition Regulation. Read each item carefully — these are legal certifications and you are signing under penalty of law.
Step 7 — Enter your financial information. Your bank routing and account number for Electronic Funds Transfer. Without this, the government cannot pay you even after you win a contract.
Step 8 — Submit and wait. After submission, SAM.gov validation typically takes one to three business days but can take up to ten. You will receive an email when your registration is active and you are eligible to bid.
Common registration mistakes that cause delays
The most common cause of registration delays is a mismatch between your SAM.gov information and your IRS records. Your legal business name must match exactly what the IRS has on file — including punctuation, abbreviations such as LLC versus L.L.C., and spacing. Discrepancies cause the registration to fail IRS validation and require correction before it can proceed.
The second most common mistake is using a P.O. Box as your physical address. SAM.gov requires a physical street address. You can list a mailing address separately, but the primary address must be a real location.
Renew every year without fail
SAM.gov registrations expire annually. You must renew your registration every 365 days or it will lapse. When your registration lapses, you are immediately ineligible to receive new contract awards — agencies are prohibited from making awards to entities with expired registrations, even if you are the best-value offeror. Set a calendar reminder 60 days before your expiration date. Renewal takes about 30 minutes if your information has not changed.
After you are registered
Once your SAM.gov registration is active, you are eligible to bid on federal contracts. Start searching for opportunities in your industry using the Contract Finder — it searches the same SAM.gov database using plain-English terms, so you do not need to navigate the full SAM.gov interface to find relevant solicitations in your state and industry.
