What Documents Does an Employer Need for I-9 Verification?

Number Name Description
1 U.S. Passport or U.S. Passport Card Employers must accept a U.S. Passport or U.S. Passport Card as valid List A documents for I-9 verification, which establish both identity and employment authorization. These documents eliminate the need for additional documentation, streamlining the onboarding process while ensuring compliance with U.S. Citizenship and Immigration Services requirements.
2 Permanent Resident Card (Form I-551) Employers must collect a valid Permanent Resident Card (Form I-551) to complete the I-9 verification, confirming the employee's lawful permanent resident status in the United States. This document serves as proof of identity and employment authorization, satisfying both List A requirements on the I-9 form.
3 Employment Authorization Document (EAD, Form I-766) Employers must review the Employment Authorization Document (EAD, Form I-766) as part of the I-9 verification to confirm a worker's legal authorization to work in the United States. The EAD contains the employee's photo, name, alien registration number, and expiration date, which are critical for validating employment eligibility under U.S. Citizenship and Immigration Services (USCIS) standards.
4 Foreign Passport with Form I-94 or I-94A An employer must collect a foreign passport accompanied by Form I-94 or I-94A to verify an employee's identity and lawful presence in the United States during the I-9 verification process. The Form I-94 or I-94A provides evidence of admission, entry date, and authorized duration of stay, which are critical for validating work authorization status.
5 Driver’s License or ID Card issued by State Employers require a valid Driver's License or ID Card issued by a state as an acceptable List B document for I-9 verification to establish an employee's identity. This document must be unexpired and contain a photograph or identifying information such as name, date of birth, gender, height, eye color, and address to meet Form I-9 requirements.
6 School ID Card with Photograph Employers require a School ID Card with a Photograph as an acceptable List B document for I-9 verification, proving the employee's identity but not employment authorization. This document must be unexpired and issued by a recognized educational institution to meet U.S. Citizenship and Immigration Services (USCIS) standards.
7 Voter Registration Card Employers must verify an employee's identity and employment authorization using acceptable documents for I-9 verification, and while a Voter Registration Card alone is not an acceptable List A, B, or C document, it can serve as supplemental evidence when paired with other required documents. The primary documents accepted include passports, driver's licenses, and Social Security cards, making the voter registration card insufficient by itself for I-9 compliance.
8 U.S. Military Card or Draft Record Employers must accept the U.S. Military Card or draft record as valid List A documents for I-9 verification, proving both identity and employment authorization. This documentation ensures compliance with USCIS requirements and facilitates accurate record-keeping in the employment eligibility verification process.
9 Military Dependent’s ID Card For I-9 verification, an employer can accept a Military Dependent's ID Card as a List A document that establishes both identity and employment authorization. This form of identification is issued by the Department of Defense and is valid for proving eligibility to work in the United States without requiring additional documents.
10 U.S. Coast Guard Merchant Mariner Card Employers must verify employment eligibility using Form I-9, where the U.S. Coast Guard Merchant Mariner Card serves as a List A document, proving both identity and employment authorization. This card contains a photograph, full name, and an expiration date, satisfying the requirements to establish work eligibility for Merchant Mariners.
11 Native American Tribal Document Employers require a Native American tribal document, such as a tribal enrollment card or census membership card, to verify identity and employment authorization for the I-9 form. These documents serve as acceptable List C documents under U.S. Citizenship and Immigration Services (USCIS) guidelines for employment eligibility verification.
12 U.S. Social Security Card Employers require the U.S. Social Security Card as an acceptable document for I-9 verification to confirm an employee's identity and employment authorization. This card, combined with other identity or employment eligibility documents listed on the I-9 form, ensures compliance with U.S. Citizenship and Immigration Services regulations.
13 Birth Certificate (certified copy or original) A certified copy or original birth certificate is an essential document for I-9 verification, serving as proof of both identity and U.S. citizenship or lawful status. Employers must ensure the document is unexpired and issued by a recognized authority to comply with Form I-9 requirements.
14 Consular Report of Birth Abroad (Form FS-240) Employers require the Consular Report of Birth Abroad (Form FS-240) as a valid document to establish both identity and employment authorization for I-9 verification purposes. This form, issued by the U.S. Department of State, serves as proof of U.S. citizenship for individuals born abroad to American parents.
15 Certification of Birth issued by U.S. State (Form DS-1350, FS-545) Employers must obtain a Certification of Birth issued by a U.S. State, such as Form DS-1350 or FS-545, as valid documentation for I-9 verification to establish an employee's identity and employment authorization. These birth certificates serve as primary evidence under List C of the I-9 documents, confirming U.S. citizenship without requiring additional documents.
16 Employment Authorization Document with Photo (Form I-688, I-688A, I-688B) Employers must accept an Employment Authorization Document with Photo (Forms I-688, I-688A, I-688B) as valid proof of identity and work authorization for I-9 verification, ensuring the employee is legally permitted to work in the United States.

17 Document for individuals under 18 (e.g., school record, doctor record) Employers must obtain appropriate documents for I-9 verification, including government-issued IDs or, for individuals under 18, acceptable alternatives such as school records, medical records, or other official documentation proving identity and work authorization. These documents ensure compliance with U.S. Citizenship and Immigration Services (USCIS) requirements under the Employment Eligibility Verification process.

Overview of I-9 Acceptable Documents

The I-9 verification process requires employers to review specific documents that establish an employee's identity and employment authorization. These documents fall into three categories: List A, List B, and List C.

List A documents prove both identity and employment authorization, such as a U.S. passport or Permanent Resident Card. List B documents establish identity only, examples include a driver's license or state ID card. List C documents demonstrate employment authorization only, like a Social Security card or birth certificate.

List A: Documents Establishing Identity and Employment Authorization

Employers must verify an employee's identity and employment authorization using specific documents listed under List A for I-9 verification. These documents simultaneously establish both identity and authorization to work in the United States.

  • U.S. Passport or Passport Card - A valid U.S. passport or passport card serves as proof of identity and employment authorization without additional documents.
  • Permanent Resident Card (Form I-551) - This green card confirms that the employee is a lawful permanent resident authorized to work in the U.S.
  • Employment Authorization Document (Form I-766) - Issued by USCIS, this card allows non-citizens temporary permission to work and verifies their identity.

List B: Documents Establishing Identity Only

Employers must collect specific documents to complete the I-9 verification process, ensuring employees' identity and employment authorization. List B documents focus solely on establishing identity without proving work authorization.

  1. Driver's License or ID Card - Issued by a state or outlying possession of the United States, containing a photograph or identifying information such as name, date of birth, gender, height, eye color, and address.
  2. ID Card Issued by Federal, State, or Local Government Agencies - Must include a photograph or information like name, date of birth, gender, height, eye color, and address for identity verification.
  3. School ID Card with a Photograph - Provided by educational institutions to confirm identity through a photo ID for students.

List C: Documents Establishing Employment Authorization Only

List C documents establish an employee's authorization to work in the United States without proving identity. Employers must review these documents to complete the I-9 Employment Eligibility Verification form accurately.

Examples of List C documents include a Social Security card, a birth certificate issued by a U.S. state or territory, and a Native American tribal document. These documents confirm the employee's employment authorization but do not serve to establish identity.

How to Review and Accept I-9 Documents

Employers must carefully review original documents presented for I-9 verification to ensure they are genuine and relate to the employee. Acceptable documents fall into three categories: List A documents prove both identity and employment authorization, while List B verifies identity only, and List C confirms employment authorization. Employers should compare document details with the employee's information and reject photocopies or expired items to maintain compliance with U.S. Citizenship and Immigration Services (USCIS) guidelines.

Common I-9 Documentation Mistakes to Avoid

Employers must carefully verify employee eligibility using the correct I-9 documentation to avoid compliance issues. Common mistakes in I-9 verification can lead to legal penalties and delayed hiring processes.

  • Using Expired Documents - Employers often accept expired identification, which invalidates the I-9 verification process.
  • Incomplete Documentation - Failing to fill out all required fields on Form I-9 can result in audit failures.
  • Accepting Unacceptable Documents - Employers must only accept documents listed on the official I-9 list to prove identity and work authorization.

Maintaining strict adherence to I-9 documentation requirements ensures smooth employment verification and legal compliance.

Retention and Storage of I-9 Forms and Documents

Employers must retain completed I-9 forms for each employee for either three years after the date of hire or one year after employment ends, whichever is later. These documents can be stored on paper, microfilm, microfiche, or electronically, provided electronic storage systems allow for accurate reproduction of the original forms. Proper security measures must be in place to protect the confidentiality and integrity of I-9 forms during storage and retention.
