TL;DR — What You Need to Know

What is SAM.gov?

SAM.gov (System for Award Management) is the official U.S. government website where businesses register to do business with the federal government. Think of it as the government's contractor directory — if you're not in it, you don't exist to federal buyers.

SAM.gov serves multiple functions:

Before You Start: Gather These Documents

Registration Checklist

Step-by-Step Registration Process

1 Create a Login.gov Account

Before you can access SAM.gov, you need a Login.gov account. This is the government's single sign-on service used across multiple federal websites.

  1. Go to login.gov and click "Create an account"
  2. Enter your email and create a password
  3. Set up multi-factor authentication (authentication app recommended)
  4. Complete identity verification — you'll need your SSN, government photo ID, and a phone number or address linked to your identity

Identity Verification Tips

Login.gov's identity proofing can be frustrating. If automated verification fails, you may need to verify in person at a USPS location. Common issues: name mismatches between your ID and credit bureau records, recently moved addresses, or photos that don't meet quality standards. Be patient — this is a one-time process.

2 Request a Unique Entity ID (UEI)

The UEI is your business's unique identifier for all federal transactions. It replaced DUNS numbers in April 2022.

  1. Go to SAM.gov and sign in with Login.gov
  2. Navigate to "Get Started" → "Get a Unique Entity ID"
  3. Enter your legal business name and address
  4. The system will search for existing entities — if your business already has a UEI (from a prior DUNS transition), it will show up
  5. If new, submit the request. Processing typically takes 1-2 business days

Your UEI is a 12-character alphanumeric code (e.g., AB1234567CD8). Save it — you'll use it for every government interaction.

3 Start Entity Registration

Once you have your UEI, you can begin the full entity registration. This is the detailed profile that makes you visible to government buyers.

  1. In SAM.gov, go to "Entity Registrations" → "Register Entity"
  2. Enter your UEI
  3. The system will pull in basic information from your UEI request
  4. You'll work through several sections (details below)

4 Core Data Section

This is the most important section. Enter:

5 NAICS Codes and Business Size

Select the NAICS codes that describe your business. You can select multiple codes, but designate one as your primary code.

For each NAICS code, the system will ask for your revenue and employee count to determine if you meet the SBA small business size standard. This determines your eligibility for small business set-aside contracts.

See our Set-Aside Programs Guide for details on size standards.

6 Financial Information

You must provide banking information for electronic funds transfer (EFT). The government pays contractors electronically — there's no option for paper checks.

Security Note

SAM.gov is a secure government system and this information is protected by federal privacy laws. However, be cautious of phishing emails pretending to be SAM.gov. Always access SAM.gov directly by typing the URL — never from email links.

7 Representations and Certifications

This section contains legally binding statements about your business. You're certifying compliance with various federal regulations (FAR and DFARS). Key certifications include:

Read each certification carefully. False statements can result in criminal penalties under 18 U.S.C. 1001.

8 Points of Contact

Designate at least two contacts:

9 Submit and Wait

After completing all sections, review everything and submit. The government will validate your information against:

Expected timeline: 7-10 business days for a new registration. Renewals are typically faster (3-5 days). During peak periods (end of fiscal year in September), processing can take 3-4 weeks.

You'll receive email notifications about your registration status. Check SAM.gov directly if you haven't heard back after 10 business days.

After Registration: What's Next?

  1. Verify your profile is active. Search for your business on SAM.gov to confirm it appears in search results.
  2. Set a renewal reminder. Registration expires after 365 days. Set calendar reminders at 60, 30, and 7 days before expiration.
  3. Start searching for opportunities. With an active registration, you can now bid on any federal contract you're qualified for.
  4. Consider set-aside certifications. If you qualify for 8(a), HUBZone, SDVOSB, or WOSB programs, apply through certify.sba.gov. See our Set-Aside Programs Guide.
  5. Subscribe to opportunity alerts. Don't check SAM.gov manually every day — let GovContract Daily deliver curated opportunities to your inbox.

Is SAM.gov registration free?

Yes, completely free. Registration, renewal, and all SAM.gov services are provided at no cost by the government. If anyone charges you for SAM.gov registration, they are selling a consulting service — the registration itself is always free at SAM.gov.
