How to Register Your Small Business on SAM.gov in 2026 — Complete Step-by-Step Guide

If you want to do business with the U.S. federal government, registration in SAM.gov is not optional — it is mandatory. Every company that bids on federal contracts, receives federal grants, or gets paid by a federal agency must be registered and active in the System for Award Management (SAM.gov).

The good news: registration is completely free. The process takes about 2-3 hours if you have your documents ready. This guide walks you through every step.

## What You Need Before You Start

Before going to SAM.gov, gather these documents:

*   **EIN (Employer Identification Number)** — your business tax ID from the IRS. If you don't have one, apply free at irs.gov. Allow 2-4 weeks before using a new EIN in SAM.gov.
    
*   **Legal Business Name** — exactly as it appears on your IRS documents
    
*   **Physical Business Address** — no P.O. boxes
    
*   **Bank Account Information** — routing number and account number for direct deposit payments
    
*   **NAICS Codes** — the industry codes that describe your business activities
    

* * *

## Step 1 — Create a Login.gov Account

SAM.gov uses Login.gov for secure authentication.

Go to **login.gov** and create an account with your business email address. You will need to set up two-factor authentication (2FA) using your phone.

**Important:** The email you use to create your Login.gov account is permanently linked to your SAM.gov profile. Use your professional business email from the start.

* * *

## Step 2 — Get Your Unique Entity ID (UEI)

Your UEI is a 12-character identifier that replaces the old DUNS number. You receive it automatically when SAM.gov validates your business name and address.

Go to **sam.gov** → Sign In → Workspace → Add New Entity → Get Started.

SAM.gov will validate your legal business name and physical address. This step typically takes 1-2 business days.

* * *

## Step 3 — Complete Your Entity Registration

Once you have your UEI, you can complete the full registration. You will need to fill out:

**Business Information**

*   Legal business name
    
*   Physical and mailing address
    
*   Fiscal year end date
    
*   Business start date
    

**Taxpayer Information**

*   EIN and taxpayer name (must match IRS records exactly)
    
*   Most recent tax return year
    

**Business Types**

*   Entity structure (LLC, Corporation, etc.)
    
*   Profit structure
    
*   Socio-economic categories (Small Business, Minority-Owned, Woman-Owned, Veteran-Owned, etc.)
    

**Goods & Services**

*   NAICS codes — add all codes that apply to your business
    
*   Product Service Codes (PSC)
    

**Financial Information**

*   Bank account for EFT payments
    
*   Whether you accept credit cards
    

**Points of Contact**

*   Accounts Receivable POC
    
*   Electronic Business POC
    
*   Government Business POC
    

* * *

## Step 4 — IRS TIN Match Validation

After you submit, the IRS validates your EIN and business name. This typically takes 1-2 business days.

**Common issue:** If you obtained your EIN recently (less than 4 weeks ago), the IRS TIN Match may fail because your EIN has not yet propagated to the IRS validation database. This is normal. Wait 2-4 weeks and resubmit.

* * *

## Step 5 — CAGE Code Assignment

After IRS validation, the Defense Logistics Agency (DLA) assigns you a CAGE code — a 5-character identifier used in procurement. This takes 1-5 business days.

* * *

## Step 6 — Registration Goes Active

Once all validations are complete, your registration becomes Active. You will receive an email confirmation at the address you used for Login.gov.

**Total processing time:** 7-12 business days after complete submission.

* * *

## Important: The Notarized Letter Requirement

Within 60 days of your registration becoming Active, you must mail a notarized letter to the Federal Service Desk designating your Entity Administrator. Failure to do so may result in your registration being deactivated.

* * *

## Tips to Avoid Common Mistakes

1.  **Match your IRS records exactly** — even a comma or period difference will cause TIN validation to fail
    
2.  **Use your professional email** — the Login.gov email cannot be changed without creating a new account
    
3.  **Renew annually** — SAM.gov registrations expire every 365 days. Set a calendar reminder.
    
4.  **Add multiple NAICS codes** — don't limit yourself to one industry category
    
5.  **Register early** — don't wait until you find a contract you want to bid on. The process takes 2 weeks minimum.

## Socio-Economic Certifications That Give You an Advantage

If you qualify for any of these, mark them in your registration:

*   **Small Business** — most businesses with under $25M annual revenue qualify
    
*   **Small Disadvantaged Business (SDB)** — minority-owned businesses with net worth under $750K
    
*   **Hispanic American Owned** — opens set-aside contracts exclusively for Hispanic-owned firms
    
*   **Woman-Owned Small Business (WOSB)** — government has a 5% spending goal for WOSBs
    
*   **Veteran-Owned Small Business (VOSB)** — dedicated contracting programs through VA and DoD
    

* * *

## What Happens After Registration

Once your registration is Active, you can:

*   Search and bid on federal contracts at sam.gov
    
*   Appear in searches by federal contracting officers
    
*   Receive direct deposit payments from federal agencies
    
*   Apply for set-aside contracts reserved for your business category
