# The Complete Guide to SAM.gov Registration and UEI Verification
## Why SAM.gov Matters (And What You Need to Know)
SAM.gov (System for Award Management) is the single, authoritative government-wide registry for all federal contracts, grants, and other financial assistance. If you want to do business with the U.S. federal government, you must be registered on SAM.gov. It's non-negotiable.
In February 2022, the federal government transitioned from using DUNS numbers to UEI (Unique Entity Identifier) as the primary business identifier for federal procurement. This represents the most significant change to federal contractor registration in decades.
**Bottom line**: If you're not on SAM.gov with an active UEI, you cannot legally be awarded federal contracts, grants, or cooperative agreements.
## Key Concepts Before You Start
### What is a UEI?
A Unique Entity Identifier (UEI) is a 12-character alphanumeric code assigned by SAM.gov that uniquely identifies your business entity. It replaces the legacy DUNS number (though DUNS numbers still exist for credit reporting purposes).
**Examples of valid UEIs**:
- ABCDE1234567
- XYZ9876543210
- 123ABCXYZ987
### How UEI Differs from DUNS
| Feature | UEI | DUNS |
|---------|-----|------|
| **Issued by** | SAM.gov | Dun & Bradstreet (private company) |
| **Cost** | Free | $80 - $500 (if purchasing from D&B) |
| **Used for federal contracting** | Yes (current) | No (legacy, being phased out) |
| **Lifetime** | As long as registration is maintained | Perpetual (with D&B) |
| **Multiple entities** | Can have multiple UEIs for one business | Can have multiple DUNS for one business |
### Why the Government Changed
The shift from DUNS to UEI happened because:
1. **Cost**: DUNS required paying Dun & Bradstreet annually; UEI is free
2. **Control**: The government wanted authority over its identifier system
3. **Efficiency**: UEI streamlines federal systems
4. **Fraud reduction**: Centralized registration reduces duplicate accounts
## SAM.gov Registration: The Complete Process
### Step 1: Prepare Your Documentation
Before you start, gather these documents:
**For All Entities**:
- Employer Identification Number (EIN) from IRS
- Business address and business type documentation
- Banking information (account number, routing number)
- Name and contact info for authorized representative
**For Sole Proprietorships**:
- Social Security Number (SSN)
- Driver's license or passport
- Self-employment tax documentation
**For Corporations, LLCs, Partnerships**:
- Formation documents (articles of incorporation, articles of organization, partnership agreement)
- Ownership structure documentation
- Federal tax ID (EIN)
**If Claiming Set-Asides (SDVOSB, Woman-Owned, etc.)**:
- Certification documentation from the SBA or respective authority
- Proof of status (VA verification, women-owned certification, etc.)
### Step 2: Create Your SAM.gov Account
**Access SAM.gov**
- Go to https://sam.gov
- Click "Register" in the upper right
- Provide email address and create a password
- Verify your email
**Designate Authorized Representative**
- The person registering must be authorized to represent the business
- This is typically the owner, CEO, or designated officer
- You can designate other authorized representatives after initial registration
### Step 3: Register Your Entity
**Entity Information**
- Legal business name (exactly as registered with state/federal authorities)
- Doing Business As (DBA) names, if applicable
- Entity type (sole proprietorship, LLC, corporation, partnership, etc.)
- Business address (principal office location)
- Congressional district where headquarters is located
**Tax Information**
- Employer Identification Number (EIN)
- Taxpayer Name (as it appears on tax forms)
- UEI will be automatically assigned
**Physical Address vs. Mailing Address**
- Physical address must be accurate (government may conduct site visits)
- Mailing address can differ if you use a PO box
- Correcting address errors after registration can delay processing
### Step 4: Provide Financial Information
**Banking Details**
- Account number
- Routing number
- Account type (checking, savings, money market)
- This information is encrypted and used for federal payments
**Why It Matters**:
- Federal payments route to the bank account you specify
- Errors cause payment delays
- Verify this information is absolutely correct
**Security Consideration**:
- SAM.gov banking data is encrypted
- Only federal payment processors access this information
- This is safer than providing banking info to individual agencies
### Step 5: Business Point of Contact
**Register at least one Point of Contact (POC)**:
- Name and title
- Phone number
- Email address
- This person receives notifications about your registration
**Secondary Points of Contact** (recommended):
- Register multiple POCs for redundancy
- Ensures federal agencies can reach you if primary POC is unavailable
- Business owner should always be a POC
### Step 6: Small Business Set-Asides (If Applicable)
If you qualify for set-asides, register them:
**SDVOSB**:
- Service-disabled veteran ownership certification (from VA VIP)
- Will automatically populate if you're verified in VA's VIP database
- Confirmation number from VIP
**Women-Owned Small Business (WOSB)**:
- Certification from SBA or designated third-party certifier
- Requires proof of majority female ownership
- Must be recertified every 3 years
**8(a) Small Business**:
- SBA Program number
- Certification status and dates
- Sponsoring SBA district office
**Historically Underutilized Business Zone (HUBZone)**:
- HUBZone certification number
- Principal office location must be in designated HUBZone
- Can be self-certified if meeting requirements
**Minority Owned Business Enterprise (MBE)**:
- Certification from state or local certifying authority
- Proof of minority ownership
### Step 7: Size Standards Self-Certification
Federal contracts are often set-aside for "small businesses," but what constitutes "small" depends on your industry:
**Manufacturing**: $500K - $8.5M average annual receipts (depending on NAICS code)
**Services/Consulting**: $7M - $38.5M average annual receipts (depending on NAICS code)
**Wholesale**: $100M average annual receipts
**Retail**: $42.5M average annual receipts
You must certify your actual size status. Misrepresenting your size is fraud and results in:
- Contract termination
- Debarment from federal contracting
- Potential criminal penalties
**Action**: Look up your NAICS code and the corresponding size standard before registering.
### Step 8: NAICS Code Selection
**What is a NAICS code?**
NAICS (North American Industry Classification System) is a 6-digit code that identifies your industry. Federal contracts are often set-aside by NAICS code.
**Examples**:
- 541519 (IT Value-Added Reseller) - Corelon's primary code
- 541512 (Computer Systems Design Services)
- 334111 (Electronic Computer Manufacturing)
- 423430 (Computer and Computer Peripheral Merchant Wholesalers)
**How to Find Your NAICS Code**:
1. Go to https://www.census.gov/cgi-bin/sssd/naics/naicsrch
2. Search for your industry
3. Select the most specific code that matches your primary business
**Why It Matters**:
- Determines which contracts you can bid on
- Affects size standard applicability
- Used for federal procurement planning
You can register up to 3 NAICS codes, but pick your primary carefully.
### Step 9: Certifications and Compliance
**Representations and Certifications (R&Cs)**:
You'll attest to numerous compliance items:
- Country of incorporation
- Business relationship with federal government
- Tax compliance
- Labor law compliance
- Environmental compliance
- Suspension and debarment status
- Drug-free workplace status (if you have federal contracts)
**Cost Accounting Standards (CAS) Coverage**:
If your anticipated federal contracts exceed $50 million, you'll need CAS coverage.
### Step 10: Review and Submit
- Review all information for accuracy (this is critical)
- Correct any errors before submission
- Submit your registration
- You'll receive a confirmation number
## After Registration: What Happens Next
### Initial Review (1-3 days)
SAM.gov reviews your registration for:
- Completeness
- Accuracy of data
- Suspension/debarment status
- Compliance with regulations
### Active Registration (3-5 business days)
Once approved, your registration becomes active. Your UEI is assigned, and you can:
- Respond to Requests for Quotation (RFQs)
- Bid on government contracts
- Access contracting opportunities
**Your UEI is now active for federal contracting.**
### Annual Re-certification Required
SAM.gov registrations must be updated annually:
- New legal certifications required
- Financial information must be current
- Point of contact must verify all information
- Failure to re-certify results in registration becoming inactive
## Common Registration Mistakes
### Mistake 1: Inaccurate Business Address
Using a residential address, a mail drop, or a temporary address can result in:
- Registration rejection
- Contract award delays
- Site visit failures if address is wrong
**Fix**: Use your actual principal office address, even if it's small.
### Mistake 2: Misrepresenting Business Size
Claiming to be a small business when you're not:
- Results in contract termination if discovered
- Can trigger debarment proceedings
- May result in criminal referral for False Claims Act violation
**Fix**: Calculate your actual size status using the SBA formula for your NAICS code.
### Mistake 3: Wrong NAICS Code
Selecting a NAICS code that doesn't match your primary business:
- Prevents you from seeing relevant contract opportunities
- Makes you ineligible for certain contracts
- Complicates future contracting
**Fix**: Spend 30 minutes finding your actual NAICS code.
### Mistake 4: Outdated Banking Information
- Federal payments route to the wrong account
- Creates cash flow problems
- Delays contract payment processing
**Fix**: Update banking info immediately if it changes.
### Mistake 5: Failing to Re-certify Annually
- Registration becomes inactive
- You can't bid on new contracts
- Existing contracts may be at risk
**Fix**: Set a calendar reminder for annual re-certification (SAM.gov sends notification emails).
## Maintaining Your SAM.gov Registration
### Annual Re-certification Checklist
**Every 12 months, you must**:
1. Log into SAM.gov with your UEI
2. Review all entity information for accuracy
3. Update any changed information (address, phone, banking, etc.)
4. Recertify representations and certifications
5. Verify all points of contact are current
6. Submit updated registration
**Timeline**: Ideally complete re-certification 60 days before your anniversary date to avoid lapsed registration.
### Updating Information Between Re-certifications
- Address change: Update immediately (physical location changes are significant)
- Phone or email change: Update within 30 days
- Banking information change: Update immediately (prevents payment delays)
- Ownership changes or company restructuring: Update within 30 days
### Suspension and Debarment
The System for Award Management (SAM) also houses the Exclusions database. You must verify:
- Your company is not suspended
- No principals are debarred
- You haven't been excluded for compliance violations
If you discover you're in the Exclusions database, contact the responsible federal agency immediately to request removal.
## UEI vs. DUNS: The Transition
### Current Status (June 2026)
- UEI is now the primary identifier for federal contracting
- Many legacy systems still reference DUNS numbers
- New contracts use UEI; existing contracts may reference DUNS
### What This Means for You
- Register on SAM.gov to get your UEI
- You don't need to obtain or maintain a separate DUNS number (unless you want credit reporting)
- Federal agencies are transitioning all systems to UEI
### The One Remaining DUNS Use
- Dun & Bradstreet DUNS numbers are still used for commercial credit reporting
- This is separate from government contracting
- You can obtain a DUNS from D&B for business credit purposes (separate process, costs money)
## Troubleshooting Common Issues
### Problem: "UEI Already Exists"
**Cause**: You already have a SAM.gov registration.
**Solution**:
1. Try to recover your password on SAM.gov
2. Log in with your email and existing credentials
3. If you forgot your information, use the "Forgot Password" function
4. Contact SAM.gov help desk (help@sam.gov) if you can't recover access
### Problem: "Registration Under Review for Extended Period"
**Cause**: SAM.gov is requesting additional documentation.
**Solution**:
1. Log into your SAM.gov account
2. Look for notifications or messages requesting additional info
3. Respond to requests immediately
4. Call SAM.gov help desk for status
### Problem: "Registered but Can't Submit Bids"
**Cause**: Registration is active, but you haven't completed step 10 (finalized registration).
**Solution**:
1. Verify your registration shows "Active" status (not "Pending")
2. Ensure your re-certification is current
3. If still unable to bid, contact SAM.gov help desk
## Strategic Tips for Success
### Tip 1: Register Early
Don't wait until you have a contract opportunity to register. Register immediately:
- Gives time for any administrative issues to resolve
- Allows you to start monitoring opportunities
- Prevents rushed registrations with errors
### Tip 2: Use Generic POC Title
When registering point of contact, use:
- "Business Owner" or "Principal"
- Not a personal name tied to one person
- Allows POC changes without re-registration
### Tip 3: Register Multiple NAICS Codes
If you operate in multiple industries:
- Register up to 3 NAICS codes
- This maximizes contract opportunity visibility
- Easier to do at registration than to add later
### Tip 4: Set Automatic Re-certification Reminder
- Calendar reminder for 90 days before anniversary
- Email reminder to all team members
- Prevents lapsed registration
### Tip 5: Document Your UEI
- Store your UEI in a safe location
- Share with your accountant and banking relationships
- Reference it in all federal proposals and correspondence
## After You're Registered: Next Steps
Once your SAM.gov registration is active with your UEI:
1. **Explore FedBizOpps**
- Visit https://sam.gov/opportunities
- Search for contract opportunities in your industry
- Set up alerts for opportunities matching your NAICS code
2. **Build Your Proposal Library**
- Create standard capability statements
