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
Match your IRS records exactly — even a comma or period difference will cause TIN validation to fail
Use your professional email — the Login.gov email cannot be changed without creating a new account
Renew annually — SAM.gov registrations expire every 365 days. Set a calendar reminder.
Add multiple NAICS codes — don't limit yourself to one industry category
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
