The Complete SAM.gov Registration Guide (and Why It Is Free)

If you want to register for government contracts, the door you walk through is SAM.gov, the official System for Award Management. Every company that sells to the federal government has to be registered there, and a single fact catches many new owners by surprise: SAM.gov registration is 100 percent free. There is no fee to register, no fee to get a UEI number, and no fee to keep your registration active. This guide is a full walkthrough of how to register on SAM, plus a clear-eyed look at the third-party fees you should avoid.

What SAM.gov registration gets you

Completing your registration does two things. First, it makes your business eligible to receive federal contracts and many federal grants. Second, it assigns you a UEI number, the 12-character identifier that replaced the old DUNS number and that follows your entity through the federal system. Without an active registration, you cannot be awarded a federal contract, so this is the true starting line for federal work.

Before you start: what to have ready

Gather these so you are not hunting for details mid-registration:

• Your legal business name and physical address, exactly as they appear on your formation documents. This is the detail that drives entity validation, so accuracy here saves the most pain later.
• Your EIN, the Employer Identification Number issued by the IRS.
• Your formation documents, such as articles of incorporation or organization, in case you need to submit them during validation.
• Banking information for electronic payment, since federal payments are made by direct deposit.
• Your NAICS codes, the classifications for the kind of work you do.

Step-by-step: how to register on SAM.gov

1. Create a Login.gov account. SAM.gov uses Login.gov for secure sign-in. Setting it up is free and takes a few minutes.
2. Start a new entity registration. Sign in to SAM.gov and begin the registration workflow for your business.
3. Validate your entity. SAM confirms your business is a unique legal entity by matching your legal name and physical address to official records, and issues your UEI. This is the step where most people get stuck, so see our dedicated guide on how to pass SAM.gov entity validation if you hit a mismatch.
4. Complete the core data sections. Provide your business details, banking information for direct deposit, points of contact, and the certifications and representations the system asks for.
5. Add your NAICS codes. Select the codes that describe your work so you appear in the right searches and size standards apply correctly.
6. Submit and wait for active status. After you submit, your registration goes through review before it becomes active. Start early so you are active before a deadline, not because of one.

Why people think it costs money (and why it does not)

A whole industry of third parties advertises "SAM registration services," and some send official-looking emails or buy ads on look-alike domains. They prey on the genuine confusion the process can cause. Here is the honest framing:

• The system itself is free. Registering, validating your entity, and getting a UEI number cost nothing on SAM.gov.
• Paying for help is a choice, not a requirement. Hiring a consultant for advice or to save time can be legitimate, but you are paying for their time, not for access to a free government system, and you should never surrender control of your registration.
• Watch for pressure tactics. Unsolicited invoices, urgent renewal warnings from non-government senders, and demands for payment or for a notarized letter are warning signs. The notarized-letter requirement was removed, so anyone insisting on one is not describing the current process.

After your registration is active

An active SAM.gov registration is the foundation, not the finish. The step that trips up the most new registrants is validation itself, so if your name or address will not match, our guide on how to pass SAM.gov entity validation is the one to keep open. Next you decide whether to pursue a small-business set-aside, which can sharply reduce your competition. Our comparison of 8(a), SDVOSB, WOSB, and HUBZone explains who qualifies for each. Then you start finding and winning work, and our step-by-step guide to winning your first federal contract lays out the full path.
