E-Verify Requirements by State: Who Actually Has to Enroll

Nine states require private employers to use E-Verify, and no two of them define “employer” the same way. Alabama, Arizona, Mississippi and South Carolina require it of every private employer. Florida sets the line at 25 employees, North Carolina at 25, Tennessee at 35 full-time equivalents, Georgia at more than 10 — counting only people who work 35 hours a week or more — and Utah at 150. Ohio joined on March 20, 2026 for nonresidential construction only. Everywhere else the obligation reaches public employers and state contractors, not the general employer. This page cites the statute for each one.

E-Verify mandatory states at a glance

If you want the list of E-Verify required states before the detail, here it is. The question that matters is not only which states, but for whom: a state can make E-Verify mandatory for every private employer, for private employers above a size, for one industry, or only for public employers and companies holding state contracts.

Every other state leaves E-Verify voluntary for private employers. At the federal level it is mandatory only for federal contractors whose contract carries FAR 52.222-54, wherever they are based. The statute behind each private-employer row, and how each state counts its threshold, is further down this page.

What E-Verify is, in one screen

E-Verify is a federal internet service that checks whether a new hire is authorized to work. In the government's own words it is "an Internet-based system that compares information entered by an employer from an employee's Form I-9, Employment Eligibility Verification, to records available to the U.S. Department of Homeland Security and the Social Security Administration to confirm employment eligibility." It is run jointly by DHS and SSA, and it is free to use.

Three things follow from that definition and they are the source of most confusion.

• It does not replace Form I-9. The I-9 comes first and E-Verify reads from it. Every employer in the United States must complete an I-9 for every new hire; E-Verify is an additional check on top, run by a minority of employers.
• It is not federally mandatory for most employers. Federal law obliges only certain federal contractors, under FAR 52.222-54. Everyone else is there because a state told them to — which is what the rest of this page is about — or because they chose to enroll.
• It is a post-hire check, not a screening tool. A case is created after the person is hired and the I-9 is complete. Running an applicant is a violation, not a shortcut.

The deadline is the third business day after they start work for pay

Not after the offer, not after the I-9, and not after the first pay run. The E-Verify User Manual is explicit: "E-Verify cases must be created no later than the third business day after the employee starts work for pay", and an employer who discovers a missed case should "bring themselves into compliance immediately by creating a case". Creating a case three or more days late forces you to pick a reason for delay from a drop-down — awaiting Social Security number, technical problems, an audit that revealed a new hire was never run, or other — so late cases are visible to the government by design.

What a mismatch actually is

If the data does not line up, the case returns a Tentative Nonconfirmation, now generally called a mismatch. Within 10 federal government working days of the mismatch the employer must notify the employee, give them a copy of the Further Action Notice, review it with them in private, and tell them they have 10 federal working days from issuance to say whether they will contest it. Until the case becomes a Final Nonconfirmation the employer may not terminate, suspend, delay training, withhold or lower pay, or take any other adverse action because of the mismatch. If the employee declines to act, the employer may close the case and may then terminate without civil or criminal liability under the memorandum of understanding.

Federal contractors: the one place federal law says you must

Where the E-Verify clause at FAR 52.222-54 is in the contract, the deadlines are fixed: enroll as a federal contractor within 30 calendar days of contract award; within 90 calendar days of enrollment begin running all new hires, each within 3 business days of the date of hire; and for each existing employee assigned to the contract, start verification within 90 calendar days of enrollment or within 30 calendar days of that assignment, whichever is later. The clause flows down to subcontracts worth more than $3,500 that include work performed in the United States.

When the system itself goes down

It happens, most recently during the funding lapse in autumn 2025, and the rule is worth knowing before you need it: the days E-Verify was unavailable do not count toward the three business days. You create the case when the service returns, select "Other" as the reason for delay, and record that E-Verify was not available. Federal contractor deadlines pause the same way, on calendar days.

Why every list you find says something different

Search this question and you will get a dozen tables that do not agree with each other. They are not sloppy so much as flattened: they compress four legally distinct obligations into a single yes-or-no column.

Statute citations for every row in the first three groups appear below. Louisiana is frequently listed as a mandate state and is not one.

The nine states that reach private employers

Each statute read at source on September 2, 2026. Ohio is listed with the private mandates because it binds private contractors directly rather than through a state contract.

The threshold is a definition, not a headcount

This is the part the tables lose, and it is the part that decides whether the rule applies to you. Five states set a number. All five count to it differently, and three of them exclude exactly the kind of worker a frontline employer has most of.

O.C.G.A. § 36-60-6; N.C.G.S. § 64-25; Tenn. Code § 50-1-703; Fla. Stat. § 448.095; Utah Code § 13-47-201.

Read across that table and the consequence is plain. A restaurant group with forty people on the payroll, half of them working twenty-five hours a week, is over the line in North Carolina and under it in Georgia. A packing operation that runs eight months of the year may employ two hundred people and count as none of them in North Carolina. A hotel counting heads in Tennessee is counting the wrong unit entirely.

What non-compliance actually costs

The federal I-9 penalty is a fine. Most state E-Verify penalties are not: they run at your license to trade. That is a different order of risk, and it is why these statutes sit with the operations team rather than with payroll.

Ala. Code § 31-13-15; Fla. Stat. § 448.095; Miss. Code § 71-11-3; S.C. Code § 41-8-20; Ohio E-Verify Workforce Integrity Act; La. R.S. 23:995. Read at source September 2, 2026.

Two things changed in 2026, and one of them did not

Ohio is new and it is live. The E-Verify Workforce Integrity Act took effect on March 20, 2026 and covers nonresidential construction contractors, subcontractors and labor brokers with no minimum size. Covered employers create cases for new hires, keep records for three years from hire or one year from termination, whichever is later, and terminate anyone who receives a final nonconfirmation. Residential building, manufactured and mobile homes, industrialized units and agricultural structures are outside it.

Florida did not change. House Bill 197 would have removed the 25-employee threshold and reached every private employer from July 1, 2026. It passed the Florida House 80 to 30 on January 15, 2026 and then died in Rules on March 13, 2026. Florida’s threshold is still 25. Any page telling you Florida is about to cover everyone was written between those two dates and never updated.

Public employers and state contractors

Outside the states above, the obligation generally attaches to government employment or to bidding for government work rather than to employing people. These are listed as reported rather than re-read at statute, because the trigger in each case is a contract you would be reading anyway.

Compiled from published state summaries rather than read at statute, and marked as such deliberately. Before relying on any row here, read the contract clause, which will state the requirement in terms your procurement team can act on.

Hiring in more than one state

The obligation follows the worksite, not the head office. An employer headquartered in a state with no mandate that opens a location in Alabama, Arizona, Mississippi or South Carolina is enrolled from its first hire there, and one crossing 25 people in Florida or North Carolina crosses into the mandate without anyone filing anything. Remote hiring makes this sharper: a company with no premises in a mandate state can still acquire the obligation by employing people who live there.

The practical reading is that E-Verify enrollment is a function of your hiring plan rather than of your current footprint. If a market you are advertising into is in one of the nine, the question is settled before the first application arrives, not after the first offer.

Where our own numbers stop

We can tell you what it costs to reach candidates in these markets, because we measure that. Across the 891 campaigns in our 2026 social job advertising benchmark the median campaign cost $13.88 per applicant, with warehouse and production roles at $9.83 and CDL drivers at $26.86. We have no data at all on E-Verify enrollment rates, tentative nonconfirmation rates, or how long a case takes to resolve, and we are not going to estimate any of them. What we would say is that the enrollment question belongs with the decision to hire in a state, not with the paperwork after it — the same argument we make about Form I-9 requirements, where the clock also starts at the hire.

E-Verify runs on what the Form I-9 already records, so the document question comes first: our guide to work authorization covers the List A, B and C documents an employer may accept and what reverification each one triggers.
