Fast, Reliable and Compliant Employment Eligibility Verification

E-Verify is a web-based program operated by the U.S. Department of Homeland Security (DHS) in partnership with the Social Security Administration (SSA). It allows enrolled employers to electronically confirm a new employee’s employment authorization by comparing information from their completed Form I-9 against government records. The process helps validate the legal name, Social Security number (SSN) and immigration status of new hires.

I-9 work verification refers to the requirement that all U.S. employers complete Form I-9 to verify the identity and employment authorization of each employee. When integrated with E-Verify, the system provides faster confirmation and flags issues such as tentative nonconfirmation (TNC) if discrepancies arise. Employers can also designate an employer agent to manage the E-Verify process on their behalf. Federal contractors and organizations with the E-Verify clause must use the system for all hires at covered hiring sites.

When E-Verify identifies a mismatch between the information provided by the employee and records held by the federal government, the employer receives a tentative nonconfirmation (TNC) notice. At that point, the employer must notify the employee promptly and provide them with a copy of the TNC and instructions on how to resolve it. The employee then decides whether to contest the result.

If the employee contests the TNC, they must contact the appropriate agency (usually USCIS or the SSA) within the timeline provided—typically eight federal government workdays. The case remains open while the employee works to correct the issue. E-Verify will return an updated result after the agency review. Employers must not take adverse action during this process. The E-Verify system also provides educational resources and webinars to help employers and employees understand how to handle these cases.
