How to Register in SAM.gov: A Step-by-Step Guide for Small Businesses (2026)

Updated July 2026 by Contract Compliance Partners

If you want to bid on federal contracts or receive payments from any U.S. government agency, you must be registered in SAM.gov (System for Award Management). SAM.gov registration is free, but the process is detailed. One small mistake can delay your CAGE code, block payments, or make your business invisible to contracting officers.

This guide walks you through exactly how to register in SAM.gov as a small business, what documents you need, how long it takes, and the most common mistakes to avoid.

What Is SAM.gov and Why Do You Need It?

SAM.gov is the federal government's official vendor database. It combines several older systems into one place where agencies find, evaluate, and pay contractors.

You must be registered in SAM.gov to:

• Bid on federal contracts and subcontracts
• Receive federal grant payments
• Get a CAGE code and UEI (Unique Entity ID)
• Appear in the Dynamic Small Business Search (DSBS)
• Apply for SBA small business certifications like 8(a), WOSB, and SDVOSB

In short: no SAM.gov registration means no federal business.

What You Need Before You Start

Gather this information before you begin. Missing details will slow you down.

• Legal business name and DBA (if any)
• Physical business address (P.O. boxes are not allowed for the main address)
• Taxpayer Identification Number (TIN/EIN)
• Banking information for Electronic Funds Transfer (EFT)
• NAICS codes that match the work you want to perform
• PSC codes (Product and Service Codes) if applicable
• Business start date and fiscal year end
• Number of employees and average annual revenue
• Banking routing and account numbers for federal payments

SAM.gov Registration: 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. Use a business email you check regularly. Set up two-factor authentication to protect your account.

Step 2: Start a New Entity Registration in SAM.gov

Log into sam.gov and select "Register Entity." Choose the type of registration you need. Most for-profit businesses select "Business or Organization."

Step 3: Enter Your Business Information

Enter your legal business name, physical address, and ownership details. Make sure the address matches IRS and Secretary of State records. Discrepancies are a common cause of delays.

Step 4: Add Your NAICS Codes

NAICS codes describe what your business does. Federal contracting officers use them to find vendors. Choose every code that matches your products or services. This is one of the most important steps for getting found.

Step 5: Complete the Representations and Certifications

These are the legal statements required to do business with the federal government. Answer truthfully. If you plan to apply for small business set-asides, make sure your size and ownership representations are accurate.

Step 6: Submit and Wait for Validation

After you submit, SAM.gov will review your registration. The system will assign a UEI and request a CAGE code validation. This process can take anywhere from a few days to several weeks depending on workload and whether corrections are needed.

How Long Does SAM.gov Registration Take?

If you have all your documents ready, filling out the application can take 2–4 hours. Federal validation usually takes 3–10 business days, but it can take longer if corrections are needed.

If you work with a consultant, the registration is typically submitted within 3–5 business days and the risk of delays is much lower.

Common SAM.gov Registration Mistakes

• Wrong address: The physical address must be a real location, not a P.O. box or virtual office.
• Incorrect NAICS codes: Missing or wrong codes make your business invisible to buyers.
• Mismatched TIN: The TIN in SAM.gov must match IRS records exactly.
• Outdated banking info: Incorrect routing or account numbers delay payments.
• Inaccurate ownership details: Errors here can disqualify you from small business set-asides.
• Not renewing: SAM.gov registrations must be renewed every 365 days.

What Is a UEI and a CAGE Code?

UEI stands for Unique Entity ID. It is a 12-character identifier assigned by SAM.gov to every registered entity.

CAGE Code (Commercial and Government Entity) is a 5-character code used to confirm your business location. It is assigned during SAM.gov validation.

You need both to do business with the federal government.
