Form I-9 Without a Social Security Number: Employer Guide

A new employee is ready to start, but their Social Security number has not arrived. Your onboarding system requires nine digits, payroll wants a completed employee record, and the hiring manager wants to know whether the start date must change.

The answer depends on separating three processes: Form I-9, E-Verify, and wage reporting. A Social Security number serves different purposes in each. Treating it as a universal prerequisite can create unnecessary hiring delays or improper document requests.

Here is a practical approach for employees who have applied for an SSN but are still waiting to receive it.

Can an employee start work without a Social Security number?

Yes, an employee who is authorized to work can generally begin employment while waiting for an SSN, provided the employer satisfies Form I-9 requirements. A missing SSN is not, by itself, proof that someone lacks employment authorization.

However, an SSN application does not grant permission to work. The employee must still establish identity and employment authorization through acceptable Form I-9 documentation.

Keep these distinctions clear:

• Form I-9 documents verification of identity and employment authorization.
• E-Verify checks information from the completed Form I-9 against government records and requires an SSN to create a case.
• Payroll and wage reporting have separate tax and reporting requirements.

A payroll software limitation does not change the underlying I-9 rules.

Is an SSN required on Form I-9?

Employers that do not participate in E-Verify

Providing an SSN in Section 1 is voluntary for employees whose employers do not participate in E-Verify. Employers should not characterize that field as a mandatory I-9 requirement when it is not.

An employer may separately need an SSN for payroll and tax reporting. Explain that purpose rather than presenting the request as a condition of completing Form I-9.

Employers that participate in E-Verify

Employees of E-Verify employers must provide an SSN for the verification process. If an employee has applied for an SSN but has not received it, the employer should complete Form I-9 on time and wait to create the E-Verify case until the number becomes available.

The SSN field can remain blank while the employee awaits the number. Once it is available, update the Form I-9 record following current USCIS instructions and create the case promptly.

Do not enter a fabricated number, another person's SSN, or an Individual Taxpayer Identification Number to bypass a required field. An ITIN is not a substitute for an SSN in E-Verify and does not establish employment authorization.

Complete Form I-9 without waiting for the SSN

The pending number does not extend the normal Form I-9 deadlines:

• The employee completes Section 1 no later than their first day of employment for pay.
• The employer completes Section 2 within three business days after that first day.
• For employment lasting fewer than three business days, Section 2 must be completed no later than the first day of employment.

The employee chooses which acceptable documents to present. They may present one acceptable List A document or an acceptable combination of List B and List C documents. For E-Verify employers, a List B document must contain a photograph.

For example, an employee may present an unexpired Permanent Resident Card as a List A document. That employee does not also need to present a Social Security card for Form I-9.

Employers should not demand a Social Security card simply because an SSN is missing from the onboarding record. Standardized Form I-9 and E-Verify support can help keep document review separate from payroll data collection.

Does an SSA application receipt satisfy Form I-9?

Not necessarily. A receipt showing that someone applied for an initial Social Security card is not an acceptable I-9 receipt merely because it comes from the Social Security Administration.

The I-9 receipt rule generally permits certain receipts for the replacement of documents that were lost, stolen, or damaged. It does not broadly allow receipts for initial document applications.

Also, not every Social Security card is an acceptable List C document. Cards bearing restrictions such as “NOT VALID FOR EMPLOYMENT” or “VALID FOR WORK ONLY WITH DHS AUTHORIZATION” are not acceptable List C documents.

If the employee cannot present acceptable documents or a qualifying receipt within the applicable timeframe, that is a separate I-9 issue. Do not treat a pending SSN application as a blanket exception.

Consult the current USCIS Handbook for Employers when evaluating documents or receipts.

How to handle E-Verify while the SSN is pending

E-Verify cannot create a case without the employee's SSN. Its guidance addresses employees who have applied for, but have not yet received, a number.

Use a controlled follow-up process:

1. Complete Form I-9 on time. Do not postpone document examination because E-Verify must wait.
2. Record why case creation is pending. Keep a factual note that the employee is awaiting an SSN, consistent with current E-Verify instructions.
3. Assign a follow-up owner. HR should know who will request the number when available and complete the case.
4. Allow the employee to work while awaiting the SSN, provided Form I-9 requirements have been met.
5. Create the case promptly once the SSN is available. Use the actual first day of employment, not an adjusted date intended to make the case appear timely.
6. Explain delayed case creation when prompted. Select the appropriate reason and provide an accurate explanation under current system instructions.

This is different from a tentative nonconfirmation: no case result exists yet. Do not treat the employee as having failed verification.

Review the current E-Verify User Manual and your team's E-Verify case deadline procedures before processing a delayed case.

Coordinate payroll without creating a second problem

Notify payroll early that the employee is awaiting an SSN. Ask payroll or your provider to identify the applicable procedure for employee setup, tax withholding, and wage reporting.

Do not assume that a workaround permitted in one system is acceptable in another. In particular, never copy a payroll placeholder into Form I-9 or E-Verify.

If a filing deadline approaches before the SSN arrives, consult current IRS and SSA instructions and your tax adviser. Reporting procedures can depend on the filing method and circumstances.

Collect the eventual SSN through an approved, access-controlled channel rather than ordinary email or team chat.

Make pending-SSN onboarding a defined workflow

For high-volume employers, a short exception checklist prevents inconsistent decisions. Track the I-9 completion date, the pending-SSN reason, the follow-up owner, and the eventual E-Verify case status. Keep the record factual and avoid unnecessary sensitive documents.

The goal is simple: complete identity and work-authorization verification on time, follow E-Verify's pending-SSN process, and resolve payroll reporting through the appropriate channels.
