Are Employers Required to Use E-Verify? Federal and State Rules Explained

Meta description: Find out when U.S. employers must use E-Verify, how federal contractor and state requirements work, and what employers must do when a case returns a mismatch.

Most U.S. employers are not required by federal law to use E-Verify. However, federal contractors covered by a specific contract clause and employers subject to certain state or local laws may have to participate. Even when E-Verify is optional, nearly all employers must complete Form I-9 for each new hire. Knowing which rules apply helps employers avoid compliance problems and use the system correctly.

What Is E-Verify?

E-Verify is a free, internet-based system operated by the U.S. Department of Homeland Security (DHS) in partnership with the Social Security Administration (SSA). Employers use it to compare information from a new employee’s Form I-9 with government records to help confirm employment eligibility.

E-Verify is not a replacement for Form I-9. Employers must complete and retain Form I-9 as required, whether or not they use E-Verify. The system also does not guarantee that an employee is authorized to work: a case may return a mismatch that needs to be addressed through the prescribed process.

Are Employers Required to Use E-Verify Under Federal Law?

There is no general federal requirement for every U.S. employer to use E-Verify. Federal law generally requires employers to verify the identity and employment authorization of employees hired in the United States by completing Form I-9. E-Verify is voluntary for many employers, but participation becomes mandatory in specific circumstances.

The main federal exception involves certain federal contracts that include an E-Verify clause. Employers may also face requirements under state or local laws, which can apply even when no federal contract is involved. As a result, the answer depends on the employer’s contracts, location, workforce, and applicable public-sector rules.

When Federal Contractors Must Use E-Verify

A federal contractor is not automatically required to use E-Verify simply because it does business with the federal government. The requirement generally applies when a covered contract includes the Federal Acquisition Regulation (FAR) E-Verify clause, FAR 52.222-54. The clause generally covers certain contracts above the applicable dollar threshold, including contracts for commercial or noncommercial services or construction performed in the United States.

Federal rules also address qualifying subcontractors. A subcontract may be covered when it is for services or construction and meets the applicable requirements; certain exceptions apply, including for some commercially available off-the-shelf products. Contract terms and exceptions can be technical, so contractors should check the actual award, the FAR clause, and agency guidance rather than assume every federal agreement is covered.

When the clause applies, the contractor generally must enroll in E-Verify and follow the contract’s verification rules. Depending on the contract and the employer’s election, verification may cover employees assigned to work on the contract, new hires, or a broader group of existing employees. The contractor must also require covered subcontractors to comply where the clause makes that obligation applicable.

Practical step: Review each federal contract for FAR 52.222-54 and confirm the enrollment and employee-verification deadlines with the contracting officer or legal adviser. The FAR text is available through the Acquisition.gov E-Verify clause.

State and Local E-Verify Requirements

States can require E-Verify for some or all employers, and local rules may add another layer. Requirements differ in whom they cover: a law may apply only to public agencies and government contractors, or it may extend to private employers based on business size, industry, or other criteria. Some states also impose rules on public benefits or business licensing.

Examples illustrate why employers should check current local law. Florida requires private employers with 25 or more employees to use E-Verify for new hires, subject to the state’s procedures. North Carolina requires certain private employers with 25 or more employees to use E-Verify, with statutory exceptions. Other states, including Arizona and Mississippi, have broad employment verification requirements. The details, definitions, and enforcement mechanisms are not identical.

State laws can change, and employee-count calculations or exemptions may depend on the wording of a particular statute. Employers operating in multiple states should identify the work location and the employing entity for each hire, then confirm the current requirements with the relevant state agency or official statute.

For a state-by-state overview, consult the E-Verify state and local laws resource and verify details with the state’s official labor, workforce, or attorney general website. A summary chart is a starting point, not a substitute for the law itself.

Form I-9 Is Required Even When E-Verify Is Not

Employers generally must complete Form I-9 for each person hired to work in the United States, regardless of citizenship or immigration status. The employee completes Section 1 by the first day of employment, and the employer completes Section 2 within three business days of the employee’s first day of work for pay. Special timing rules may apply to short-term employment.

Employers must allow employees to choose which acceptable documents to present from the Form I-9 Lists of Acceptable Documents. They may not demand a particular document, such as a green card or passport, because of an employee’s citizenship, immigration status, or national origin. This anti-discrimination principle applies whether or not the employer uses E-Verify.

Employers must retain completed Forms I-9 for the required period: three years after the date of hire or one year after employment ends, whichever is later. E-Verify participants may have additional recordkeeping responsibilities, including retaining case details and following the program’s rules.

How Employers Use E-Verify Correctly

For a participating employer, the basic process begins after the employee accepts a job offer and completes Form I-9. The employer enters the I-9 information into E-Verify within the required timeframe. Under the general program rules, a case is usually created no later than the third business day after the employee starts work for pay, though special rules and exceptions can apply.

1. Complete Form I-9 first. E-Verify information must be based on the completed I-9, not used to screen applicants before a job offer.
2. Create a case on time. Follow E-Verify deadlines and use the system for all covered new hires as required by the employer’s enrollment terms and applicable law.
3. Review the result. A case may return an employment-authorized result, an interim status, or a mismatch requiring further action.
4. Protect the employee’s rights. Follow the notice and referral process if the employee receives a mismatch, and do not take prohibited adverse action.

Employers must not use E-Verify to prescreen job applicants, selectively verify employees based on perceived citizenship or national origin, or create cases for existing employees except where a specific rule permits it, such as a covered federal contractor provision. E-Verify participation does not authorize different treatment during hiring.

What Happens When E-Verify Returns a Mismatch?

A mismatch, often called a Tentative Nonconfirmation (TNC), means that the information entered into E-Verify did not match records available to DHS or SSA. It does not, by itself, mean that the employee is unauthorized to work. Errors in names, dates, or data entry, as well as records that have not been updated, can contribute to a mismatch.

The employer must notify the employee promptly and privately, provide the required notice, and explain how to take action. The employee chooses whether to contest the result. If the employee contests, the employer must give instructions for contacting the appropriate agency and allow the employee to continue working while the case is pending, as required by program rules.

Employers may not fire, suspend, delay training, reduce hours, or otherwise take adverse action against an employee solely because of a TNC while the employee is contesting it or while the case remains unresolved. Employers should follow the current E-Verify instructions and keep a record of notices and case actions. A final result is handled according to the system’s rules and does not excuse the employer from following anti-discrimination laws.

What Are the Risks of Ignoring a Requirement?

Employers that fail to complete Form I-9 or follow applicable E-Verify obligations may face government investigations, civil penalties, contract consequences, or loss of eligibility for certain public contracts or benefits. The specific outcome depends on the violation, the governing law, the employer’s history, and the facts of the case.

Using E-Verify improperly can also create legal exposure. Examples include prescreening applicants, failing to notify employees about a mismatch, taking action before the process is complete, or treating workers differently based on citizenship or national origin. A sound compliance process should address both verification rules and employee protections.

How to Determine Whether E-Verify Is Required

Employers can use a simple review to identify likely obligations, while seeking qualified advice when a rule is unclear:

• Check federal contracts. Look for FAR 52.222-54 in each relevant contract and review covered subcontract obligations.
• Check every work location. Review state and local rules for the location where each employee works, not just the company’s headquarters.
• Confirm employer coverage. Check employee-count thresholds, public-contract status, industry rules, and exemptions.
• Maintain Form I-9 compliance. E-Verify does not replace I-9 completion, document-choice rules, or retention requirements.
• Train hiring staff. Make sure staff understand case deadlines, mismatch procedures, privacy, and anti-discrimination obligations.
• Recheck periodically. Laws and contract terms can change, so review requirements when entering a contract, opening a location, or changing workforce size.

Reliable Sources for E-Verify Rules

Official resources are the best place to confirm current requirements. The E-Verify website explains enrollment, case procedures, and employer responsibilities. U.S. Citizenship and Immigration Services provides the current Form I-9 Central guidance. Employers can also review the federal contract clause through Acquisition.gov and check state requirements with the relevant state agency.

In short, most employers are not required to use E-Verify under federal law alone, but Form I-9 is generally required. E-Verify becomes mandatory for employers covered by particular federal contracts or state and local laws. Because those rules vary, employers should verify obligations for each contract and work location before hiring.
