SAM.gov is the government's own registration system. Being registered and active there is what makes your business eligible to be awarded federal contracts and to get paid. It costs nothing, and you can do the whole thing in an afternoon plus a validation wait.

1 · Get a Login.gov account

SAM.gov signs you in through Login.gov, the government's shared login. Create the account with an email you check, and set up two-factor sign-in when it asks. Five minutes.

2 · Gather what the form will ask for

Have these ready before you start, because stopping mid-registration is where momentum goes to die:

• Your legal business name and physical address, exactly as the IRS has them
• Your EIN (or SSN for a sole proprietor)
• Bank account and routing numbers, for getting paid
• The date and state of your incorporation or formation
• A rough list of what you sell, so you can pick industry codes

The single most common failure: the legal business name not matching IRS records character for character. "Inc" versus "Inc." can fail validation and cost you a week. Copy the name from an IRS document, not from memory.

3 · Request your UEI and complete entity registration

Inside SAM.gov, start an entity registration. Early in the flow you get a Unique Entity ID, the 12-character ID that replaced the old DUNS number. Then the long form: business details, banking, and your NAICS codes, the industry labels agencies use to find businesses like yours.

The NAICS choices matter more than they look. They quietly decide which opportunities you match for the next year. Pick the codes that describe what you actually do, not everything you might do. If you set up a free Quarry account, describe your work in plain English during setup and we map the codes for you.

4 · Wait for validation

After you submit, SAM validates your entity against IRS and banking records. Plan on 7 to 14 days; it can run longer when documents get requested. You will get email when your registration goes active. Nothing else happens until it does, so this is a good week to read about notice types.

5 · Mark your renewal date

Registrations expire after one year, and an expired registration means you cannot be awarded anything until it is renewed. Put the renewal date somewhere you will actually see it. Renewal is the same process, shorter, and also free.
