What Is E-Verify?
E-Verify is an electronic system that compares your Form I-9 information to government records.
How it works:
- You complete Form I-9 with your employer
- Employer enters your information into E-Verify
- E-Verify checks DHS and SSA records
- The system returns a result
What E-Verify checks:
- Social Security Number matches name and date of birth (SSA)
- Work authorization is valid (DHS)
- Photo match for certain documents
E-Verify is not:
- A background check
- A credit check
- A criminal-history search
E-Verify only checks employment-authorization records.
Which Employers Use E-Verify?
E-Verify is mandatory for some employers and optional for others:
Required to use E-Verify:
- Federal contractors and subcontractors in covered situations
- Employers in some states or programs
Voluntarily using E-Verify:
- Many large employers choose to participate
- Participation can be part of a broader compliance process
Many staffing apps use E-Verify:
Many staffing apps use E-Verify as part of onboarding. That means your I-9 information is electronically checked and you will be notified if follow-up is needed.
How to know if your employer uses E-Verify:
- Look for the E-Verify participation poster
- Ask during the hiring process
- Check the job posting or onboarding materials
How Does the E-Verify Process Work?
Here's what happens when your employer runs E-Verify:
Step 1: You complete Form I-9
- Fill out Section 1 of Form I-9
- Provide SSN if required by an E-Verify employer
- Present acceptable documents to employer
Step 2: Employer enters information
- Employer completes Section 2
- Employer enters your information into E-Verify
- This must happen within the employer's required timeline
Step 3: E-Verify checks records
System compares against:
- SSA records
- DHS records
Step 4: A result is returned
Many cases resolve quickly, but mismatch and photo-match cases can take longer.
What Is a Tentative Nonconfirmation (TNC)?
If E-Verify finds a mismatch, you receive a TNC. But don't panic:
What Causes a TNC:
- Name mismatch (spelling, maiden name, changed name)
- SSN entry error
- Date of birth discrepancy
- Recent name change not updated in SSA records
- USCIS records not yet updated
- Citizenship status recently changed
Your Rights During a TNC:
✓ You can continue working while contesting ✓ You cannot be fired solely due to TNC ✓ You have 8 federal business days to decide whether to contest ✓ You choose whether to take action or not
If You Receive a TNC:
- Employer notifies you in private
- You receive the Further Action Notice
- Decide: Contest or don't contest
- If contesting, you have 8 federal business days to contact SSA or DHS
Two Types of TNCs:
Important: A TNC doesn't mean you did anything wrong. Records sometimes have errors, or recent changes haven't been processed.
How Do You Resolve a TNC?
If you receive a Tentative Nonconfirmation and choose to contest:
Step 1: Review the Notice
Your employer gives you:
- E-Verify Further Action Notice
- Specific instructions for your TNC type
- Referral letter (DHS cases)
Step 2: Decide to Contest
- You have 8 federal business days to decide
- If you don't contest, employer can terminate
- Contesting preserves your right to work while resolving
Step 3: Contact the Right Agency
For SSA TNC (Social Security mismatch):
- Visit your local SSA office in person
- Bring your Social Security card and photo ID
- Explain the TNC situation
- SSA will verify or correct records
For DHS TNC (Immigration records):
- Call DHS: 888-897-7781
- Or visit uscis.gov/everify
- Provide case number from referral letter
- DHS will investigate and respond
Step 4: Resolution
- Agency resolves the TNC
- E-Verify case is updated
- Employer receives new result
Timeline:
During This Time:
- You continue working normally
- Employer cannot take adverse action
- Document everything
What Is Photo Matching in E-Verify?
Some documents trigger photo matching in E-Verify:
Documents That Trigger Photo Match:
- U.S. Passport
- Passport Card
- Permanent Resident Card (Green Card)
- Employment Authorization Document (EAD)
How Photo Match Works:
- E-Verify retrieves photo from government database
- Employer compares database photo to:
- Photo on your document
- Your actual appearance
- Employer confirms match or reports mismatch
What If Photo Doesn't Match?
Possible reasons:
- Old photo in database (significant appearance change)
- Database hasn't been updated with new document photo
- Document error
If Photo Match Fails:
- Employer will follow E-Verify procedures
- May result in additional verification
- DHS will be notified if needed
- You may need to provide additional documentation
Tips for Photo Match Success:
- Use current, valid documents
- Ensure your appearance is similar to document photo
- If you've changed significantly (weight, hair, etc.), be prepared to explain
How Does E-Verify Work During Staffing-App Onboarding?
Many staffing apps use E-Verify. Here's what to expect:
During onboarding:
- Download the app
- Create profile and schedule verification interview
- Complete Section 1 of Form I-9
- Present original I-9 documents
- Your information is submitted to E-Verify
After submission:
- You'll be notified when cleared to book shifts
- If a TNC occurs, the app's support team will contact you with next steps
If You get a TNC:
- You can still work while taking action to resolve it
- Follow the resolution process above
- Keep the app's support team informed of your progress
- Provide documentation once resolved
Tips for smooth verification:
✓ Double-check your SSN before submitting ✓ Use documents with your current legal name ✓ If your name changed recently, update SSA first ✓ Bring original, unexpired documents
See our I-9 Documents List to prepare.
How Can You Check Your Records Before Applying?
If you've recently changed your name, updated your immigration status, or received a new document, review your records before applying for jobs.
USCIS says workers should make sure the information they put on Form I-9 is accurate, and E-Verify worker guidance says you should contact SSA if you recently changed your name, citizenship, or immigration status.
Good times to check your records:
- After a name change
- After receiving a new EAD or Green Card
- After a citizenship-status update
- After a prior mismatch problem
Practical first steps:
- Review your Social Security card and identification details
- Make sure your legal name matches your records
- Update SSA if your name or status changed
- Review the latest USCIS or E-Verify worker guidance before onboarding
