Social Security numbers work the same way everywhere, but the rules about when you need one and what you can do without one vary by state

Your Social Security number is issued by the federal government and is valid in all 50 states. However, states set their own rules about which documents require a Social Security number, which services you can access without one, and what identification alternatives they accept. A state might let you get a driver's license without a Social Security number while another requires it. Some states let you open a bank account with an Individual Taxpayer Identification Number (ITIN) instead; others do not. These differences matter most when you are applying for housing, employment, education, or state benefits.

Key Takeaways

  • States control whether a Social Security number is required for driver's licenses, state ID cards, bank accounts, and rental housing applications.
  • Some states accept an Individual Taxpayer Identification Number (ITIN) as an alternative to a Social Security number for certain services; others do not.
  • Employment verification rules differ by state — some employers can verify work history without a Social Security number, while others cannot.
  • State benefit programs (housing assistance, food assistance, Medicaid) each set their own Social Security number requirements, which may differ from federal rules.
  • If you do not have a Social Security number, contact your state's motor vehicle department, banking regulator, or housing authority directly to learn what documents they accept.

Driver's licenses and state ID cards

Most states now require a Social Security number to get a driver's license or state ID card, but the rule is not universal. Some states allow you to obtain a license using an ITIN, a passport, or a combination of other documents. A few states issue licenses to people without a Social Security number at all, though they may mark the license differently or restrict its use for federal purposes like boarding an airplane.

Your state's motor vehicle department controls this rule. Contact them directly — usually through their website or a local office — to find out what documents they accept and whether you can get a license without a Social Security number. If you cannot get a standard license, ask whether your state offers an alternative ID card and what it can be used for.

Bank accounts and financial services

Banks are regulated by federal law, but states can impose additional requirements. Most banks require a Social Security number to open a checking or savings account because federal anti-money-laundering rules require them to verify your identity. However, some banks and credit unions accept an ITIN instead, particularly in states with large immigrant populations or states that have passed laws encouraging financial inclusion.

If you do not have a Social Security number, call banks and credit unions in your area and ask whether they accept an ITIN. Some may require additional documents like a passport, a lease, or utility bills to verify your identity. Community banks and credit unions are sometimes more flexible than large national chains. If you cannot open a traditional bank account, some states allow you to use prepaid cards or money transfer services, though these usually charge fees.

Rental housing and lease applications

Landlords and property management companies are not required by federal law to ask for a Social Security number, but many do to run background checks and verify rental history. State laws vary on whether landlords can refuse to rent to someone without a Social Security number. Some states have passed laws prohibiting discrimination based on immigration status, which limits a landlord's ability to require a Social Security number as a condition of renting.

If a landlord asks for a Social Security number and you do not have one, ask whether they will accept an ITIN, a passport, or a combination of other documents instead. Some landlords will work with you; others will not. If you believe a landlord has refused to rent to you because you lack a Social Security number and your state has an anti-discrimination law, contact your state's housing authority or a local legal aid organization.

Employment and work verification

Federal law requires employers to verify that all employees are authorized to work in the United States using the I-9 form. The I-9 process accepts a Social Security number but also accepts other documents like a passport, a work permit, or a state ID. However, some employers use E-Verify, a federal system that checks Social Security numbers against government records. E-Verify is mandatory for federal contractors and some state employers, but not for all private employers.

States cannot override federal employment verification rules, but some states have passed laws limiting when E-Verify can be used or requiring employers to give workers a chance to correct errors before firing them. If an employer tells you that you must have a Social Security number to work, ask whether they use E-Verify and whether they will accept alternative work authorization documents. If you believe you have been discriminated against, contact your state's labor department or a local legal aid organization.

State benefit programs and housing assistance

Each state runs its own housing assistance, food assistance, and Medicaid programs, and each sets its own rules about Social Security numbers. Some states require a Social Security number to receive any state benefit. Others allow you to receive benefits using an ITIN or a state ID number instead. A few states have created alternative identification numbers for people without a Social Security number.

To find out what your state requires, contact your state's housing authority, department of social services, or Medicaid office directly. You can also call 211 (a free referral line available in most states) and ask what documents you need to apply for housing or other assistance. Having the right documents ready before you apply will speed up the process.

What to do if you do not have a Social Security number

If you are in the United States legally but do not have a Social Security number, you can apply for one through the Social Security Administration. You will need to show proof of identity, proof of immigration status, and proof of a U.S. address. The process usually takes one to two weeks. You can apply in person at a local Social Security office or, in some cases, by mail.

If you are not may be able to access for a Social Security number, you may be able to get an Individual Taxpayer Identification Number (ITIN) from the Internal Revenue Service. An ITIN is a nine-digit number used for tax purposes and is accepted by some banks, landlords, and state agencies as an alternative to a Social Security number. You can apply for an ITIN by filing a tax return or by submitting Form W-7 to the IRS.

Before you apply for either number, contact the specific organization (bank, landlord, state agency) that is asking for it and ask what documents they will accept. You may not need a Social Security number or ITIN at all — some organizations will work with you using a passport, a state ID, or other documents.

Frequently Asked Questions

Can I get a driver's license without a Social Security number?

It depends on your state. Some states require a Social Security number for all driver's licenses. Others accept an ITIN, a passport, or other documents instead.

Will a bank let me open an account with an ITIN instead of a Social Security number?

Some banks and credit unions do, but not all. Federal law does not require banks to accept an ITIN, so it depends on the bank's policy. Call banks and credit unions in your area and ask. Community banks and credit unions are sometimes more flexible than large national chains.
