E-Verify requirements in Arizona: the Legal Arizona Workers Act, plain

As of September 2026, Arizona requires every employer in the state to verify the employment eligibility of new hires through E-Verify, under A.R.S. section 23-214, part of the Legal Arizona Workers Act. The mandate has applied to every employer, regardless of size, since the law took effect for hires after December 31, 2007. What makes Arizona's version notable is not the enrollment rule itself, which is one of the more straightforward among mandate states, but the penalty structure behind it: a county attorney can ask a court to suspend or permanently revoke a noncompliant employer's business license.

Who is covered

There is no exemption in the statute for small employers, part-time or seasonal hiring, or independent contractor arrangements that function as employment. Public employers are not separately addressed by section 23-214 in the way some other states' laws call them out, because the Arizona statute's "every employer" language does not distinguish by employer type in the first place.

What Arizona employers must do, and by when

1. Register with E-Verify before hiring, if not already enrolled.
2. Complete Form I-9 for the new hire in full, on the standard federal timeline.
3. Create the E-Verify case once the I-9 is complete. Arizona's statute does not set its own separate deadline distinct from the federal E-Verify timing rules, which expect the case within three employer business days of the start date.
4. Resolve any tentative nonconfirmation under the federal process before taking adverse action.
5. Keep the case record for the duration of the employee's employment or three years, whichever is longer. This is Arizona's own statutory rule, separate from the federal I-9 retention period, and it is longer than the federal I-9 rule in most cases because it runs for the full length of the employment relationship rather than stopping three years after hire.

Records to keep

Section 23-214's own record rule (duration of employment or three years, whichever is longer) is the number to build a retention policy around in Arizona, because it can exceed the federal I-9 retention period for a long-tenured employee. In practice that means an Arizona employer needs a process for retaining the E-Verify case result past the point where the I-9 itself might otherwise be purged, for as long as the person remains employed. Keep the confirmation or final nonconfirmation screen with the employee's personnel file, not just with the I-9, so the three-statute clocks involved (I-9, federal E-Verify guidance, and Arizona's own rule) do not silently fall out of sync.

Penalties: the license consequences that give Arizona's law its reputation

Arizona does not fine an employer for the act of not enrolling in E-Verify. The exposure runs through a separate prohibition on knowingly or intentionally employing an unauthorized alien, investigated on a complaint and brought as a civil action by the county attorney in the county where the person was employed.

• Knowing violation, first occurrence (§ 23-212): the court orders termination of the unauthorized worker's employment, places the employer on a probationary period during which it must file compliance reports with the county attorney, and may suspend all licenses specific to the business location for up to 10 business days.
• Knowing violation, second occurrence at the same location: permanent revocation of the licenses specific to that location.
• Intentional violation (§ 23-212.01): a separate, more serious track for employers found to have intentionally, not just knowingly, employed an unauthorized worker, with its own probation and suspension provisions that mirror section 23-212 but attach to a higher standard of proof.
• Reinstatement: a suspended license is reinstated once the employer files the required sworn affidavit; the statute directs that reinstatement happen immediately once the affidavit is filed.

"License" in this context is defined broadly in the Act to include the range of state and local licenses, certificates, and permits a business needs to operate, which is why practitioners in Arizona sometimes call this the "business death penalty": a second violation does not just cost a fine, it can end the business's ability to legally operate at that location at all.

Good-faith E-Verify use is the main defense available to an employer facing a complaint. The statute treats proper use of E-Verify, and a resulting confirmation, as creating a rebuttable presumption that the employer did not knowingly employ an unauthorized worker for that hire. It is a presumption, not blanket immunity: a county attorney can still bring a case if other evidence shows the employer had actual knowledge, but the E-Verify record is the single best piece of documentation an Arizona employer can produce if a complaint is ever filed.

A worked example: two Phoenix employers, one hire each

This is an invented example to show how the presumption works, not a real company. Two 20-person warehouse operators in Phoenix each hire a worker who, months later, turns out not to be authorized to work. The first operator never enrolled in E-Verify; it relied on the documents the worker presented for Form I-9 and took them at face value. The second operator ran the same hire through E-Verify and received a confirmation before the worker started.

If a complaint reaches the county attorney, the second operator can point to the E-Verify confirmation as evidence supporting the rebuttable presumption that it did not knowingly employ an unauthorized worker for that hire. The first operator has no equivalent record and has to rely entirely on whatever else it can show about what it knew at the time, which is a much harder position in front of a court. Neither operator did anything to guarantee the worker's authorization was genuine, since a confirmation can be produced by identity fraud that E-Verify itself cannot catch, but only one of the two has the paper trail the statute treats as the strongest available defense.

How this sits on top of Form I-9

E-Verify runs off the data entered on Form I-9 and cannot be used before the I-9 is complete. Arizona's statute requires E-Verify as an addition to the I-9, not a replacement for it: an employer still completes Section 1 and Section 2 on the federal timeline, and only then creates the E-Verify case. Running a check before an offer is extended and accepted is not what the Arizona statute asks for, and using E-Verify to screen candidates before hire falls outside the good-faith use the presumption in section 23-212 is built on.

What a staffing agency placing workers into Arizona must do

A staffing or recruiting agency that employs its own workers and assigns them into Arizona is itself an employer under section 23-214, regardless of where the agency is headquartered or where its client is based. The agency needs to be enrolled in E-Verify, needs to run its own new hires through it before or as they start Arizona assignments, and needs to keep the record for the duration of that person's employment or three years, whichever is longer, using the agency's own employment relationship with the worker as the clock, not the length of any single client assignment. Because the license-suspension exposure in section 23-212 attaches to the business found to have knowingly employed the unauthorized worker, an agency cannot rely on a client's E-Verify enrollment to cover the agency's own hiring; the client's compliance and the agency's compliance are separate questions, each carrying its own license risk.

A compliance checklist for Arizona employers

1. Confirm the business, not an individual manager, holds the E-Verify enrollment.
2. Complete Form I-9 in full for every new Arizona hire, regardless of headcount.
3. Create the E-Verify case once the I-9 is complete, and keep the result with the personnel file.
4. Track retention against the longer of the employee's actual tenure or three years, not the federal I-9 clock alone.
5. If applying for a government contract or an economic development incentive, gather proof of E-Verify registration before applying.
6. If using a staffing agency for Arizona roles, confirm in writing that the agency runs its own E-Verify checks on the workers it assigns, rather than assuming the agency's compliance mirrors your own.
7. Do not use E-Verify to screen a candidate before an offer is made and accepted.
