Step 1: Create a Login.gov Account

Go to login.gov and create an account. This is the authentication system used by SAM.gov and many other government websites. You'll need a valid email address and phone number.

Step 2: Go to SAM.gov

Navigate to sam.gov and click "Get Started" under Entity Registration. Sign in with your Login.gov credentials.

Step 3: Get Your UEI

If you don't have a Unique Entity Identifier, SAM.gov will assign one during registration. This replaces the old DUNS number system.
