E-Verify vs Form I-9: what each one does, and what changes when you use both

Form I-9 and E-Verify are often mentioned together, but they are different obligations. Form I-9 is the paper or electronic form every U.S. employer must complete for every new hire, where the employer examines identity and work authorization documents in person or by an approved alternative. E-Verify is an online system that takes information from that completed form and checks it against Department of Homeland Security and Social Security Administration records. Form I-9 is universal. E-Verify is voluntary for most employers, required for some, and adds its own rules on top of the form once you use it.

Side by side

What E-Verify adds to the Form I-9 process

Enrolling does not change the Form I-9 itself, but it changes how you complete it. The memorandum of understanding lists two Form I-9 modifications: List B documents must have a photo, and you must copy any U.S. passport, passport card, Permanent Resident Card or EAD presented, for photo matching. On top of that:

• The Social Security number becomes mandatory in Section 1, because a case cannot be created without it. If a new hire has applied for a number but does not have it yet, the user manual says to let them keep working and create the case when the number arrives, noting the reason for the delay.
• The case number goes on the form. You record it on the Form I-9 or attach the case details page.
• Notices go up. The Notice of E-Verify Participation and the Right to Work poster, in English and Spanish, including for remote employees.
• Mismatches have a process. A tentative nonconfirmation must be shared with the employee, and no adverse action is allowed while it is pending. See E-Verify tentative nonconfirmation and E-Verify case results explained.

Timing is stricter in one sense. E-Verify's terms prohibit creating a case before the employee is hired, meaning a firm offer was made and accepted and the Form I-9 was completed. Neither process can be used to screen candidates; see Form I-9 timing in hiring.

What E-Verify does not replace

Every Form I-9 obligation continues for E-Verify employers. The memorandum of understanding says so directly: the employer remains responsible for completing, retaining and making Forms I-9 available for inspection, and for complying with the anti-discrimination rules. In practice that means:

• A late or incomplete Form I-9 is a paperwork violation even if the E-Verify case came back Employment Authorized.
• Reverification still happens on Supplement B, on time, without a new case.
• Retention follows the Form I-9 formula. E-Verify itself disposes of case records over 10 years old each year.
• Document abuse rules still apply. You may say that a List B document must have a photo, but you cannot tell the employee which document to bring.

What you get for the extra work

• A rebuttable presumption. Under the memorandum of understanding, confirming a new hire's identity and employment eligibility through E-Verify creates a rebuttable presumption that the employer has not knowingly hired that person in violation of the law.
• Good-faith protection. The memorandum also says no participant is civilly or criminally liable under any law for action taken in good faith based on information provided through E-Verify.
• Remote examination. Employers enrolled and in good standing can use the DHS alternative procedure instead of finding an authorized representative for every remote hire. See I-9 remote verification.
• Compliance where required. For federal contractors and employers in mandatory states, it is not optional; see E-Verify requirements by state.

What it costs, and the new risks

E-Verify is free to use. The costs are process and risk:

• After a Final Nonconfirmation. If you keep employing the person, you must notify DHS. Failing to notify carries a civil penalty of $998 to $1,992 per individual (the 2025 inflation-adjusted range, unchanged for 2026), and continuing to employ creates a rebuttable presumption that you knowingly employed an unauthorized worker.
• Consistency. You must verify every new hire at participating sites, not a selection, and apply the same rehire approach to everyone.
• Account compliance. E-Verify monitors user activity, and misuse or discriminatory practices can lead to suspension or termination of access.
• Mismatch handling. Someone must manage notices, referrals and case closures on deadlines measured in federal government working days.

Paperwork penalty ranges for Form I-9 itself are covered in I-9 penalties.

A worked example

The facts are illustrative. Two companies each hire a remote engineer who starts on a Monday.

Company A does not use E-Verify. The engineer completes Section 1 by Monday, leaving the SSN blank, as permitted. Company A cannot use the live-video alternative procedure, so it sends the engineer to an authorized representative, a local notary it has briefed, who examines the documents in person and completes Section 2 by Thursday.

Company B uses E-Verify and is in good standing. The engineer completes Section 1, including the SSN. The engineer uploads copies of a U.S. passport, and an HR coordinator examines the original over live video, checks the alternative procedure box and keeps the copies. HR creates the case by Thursday, completes photo matching with the passport copy, receives Employment Authorized, and records the case number on the form. Both companies still keep the Form I-9 for the same retention period.

Misconceptions that cause trouble

Should you use E-Verify voluntarily?

Questions worth answering before you enroll:

• How many remote hires do you make, and how hard is it to arrange authorized representatives?
• Do you expect federal contracts with the FAR clause, or hiring in a mandatory state?
• Can you staff mismatch handling reliably, including the no-adverse-action rule?
• Can you apply it to every new hire at the sites you enroll, including seasonal and rehired staff?

If the answers point to yes, E-Verify enrollment steps walks through the sign-up.
