Most banks require a Social Security number, but alternatives exist

Yes, most banks and credit unions will ask for your Social Security number (SSN) when you open a checking account. They use it to run a background check through ChexSystems or Early Warning Services, which are consumer reporting agencies that track banking history. If you don't have an SSN, you have options: some banks accept an Individual Taxpayer Identification Number (ITIN), some will open accounts without either number, and a few credit unions have specific programs for people without SSNs.

The requirement exists because banks are legally required to verify your identity and check for fraud or unpaid overdrafts at other institutions. However, the law does not explicitly require an SSN—banks choose to use it as their verification method. That means you can shop around.

Key Takeaways

  • Most major banks require an SSN to open a checking account, but some regional banks and credit unions will accept an ITIN or open accounts without either.
  • Banks use your SSN to check ChexSystems and Early Warning Services for fraud history and unpaid overdrafts at other banks.
  • If you have an ITIN (issued by the IRS to people who file taxes but don't have an SSN), several banks will accept it in place of an SSN.
  • Some credit unions and community banks have no-SSN checking accounts, though they may charge higher fees or require a larger opening deposit.
  • You will need to bring a government-issued photo ID and proof of address no matter which route you choose.

Banks that accept an ITIN instead of an SSN

If you have an Individual Taxpayer Identification Number, several national and regional banks will open a checking account using it. An ITIN is a nine-digit number issued by the IRS to people who file taxes but are not may be able to access for an SSN—typically immigrants, visa holders, and some others. It looks like an SSN but starts with 9.

Banks known to accept ITINs include Banco Popular, BBVA USA, Citibank, and Wells Fargo, though policies vary by branch and change over time. Call your local branch before you go in, because the person answering the phone can tell you whether they will open an account with an ITIN. Some branches accept them; others do not. Online banks are less likely to accept ITINs because they cannot verify your identity in person.

Bring your ITIN documentation (the IRS letter that issued it), a government-issued photo ID, and proof of your current address. The address proof can be a utility bill, lease, or bank statement in your name dated within the last 60 days.

Credit unions and community banks without SSN requirements

Some credit unions and smaller regional banks will open checking accounts without an SSN or ITIN. These institutions often serve immigrant communities or have a mission to provide banking to underbanked populations. Examples include certain branches of Self-Help Credit Union, some community development financial institutions (CDFIs), and local credit unions in areas with large immigrant populations.

The catch is that these accounts often come with trade-offs. Fees may be higher, minimum opening deposits larger, or the account may have limits on the number of withdrawals per month. Some require you to join the credit union first (which may involve buying a share or making a small deposit) before opening a checking account.

To find one near you, search for "credit union no SSN" or "CDFI checking account" plus your city name. You can also call 211 (a helpline that connects you to local services) and ask for banking resources for people without an SSN. Community action agencies and immigrant advocacy organizations in your area often maintain lists of banks that will work with you.

What banks check when you provide an SSN

When you give a bank your SSN, they run it through ChexSystems or Early Warning Services. These are not credit bureaus—they do not look at your credit score. Instead, they check for a history of fraud, unpaid overdrafts, or accounts closed due to suspicious activity at other banks.

If ChexSystems or Early Warning finds a problem, the bank may deny your account. You have the right to see what they found about you. You can request a free report from ChexSystems at chexsystems.com or from Early Warning Services at earlywarning.com. If there is an error, you can dispute it directly with the agency.

Some banks use a softer version of this check and will open an account even if you have a ChexSystems record, though they may charge higher fees or require a larger deposit. Others will not. This is why calling ahead matters—you can ask whether they will work with you if you have a previous banking issue.

What to bring when you open an account without an SSN

Whether you have an SSN, ITIN, or neither, you will need to bring a government-issued photo ID and proof of your current address. The photo ID can be a passport, driver's license, state ID card, or consular ID (issued by your country's embassy or consulate). The address proof must be dated within the last 60 days and can be a utility bill, lease agreement, bank statement, or government mail.

If you are opening an account in person at a branch, bring originals. If you are opening online, you will need to upload images of both documents. Some banks will also ask for a phone number and email address. A few may ask for a second form of ID if your first one does not have your address on it.

If you do not have a current address (you are unhoused or living with someone else), some banks will accept mail sent to you at a shelter, a friend's address, or a community organization. Call ahead and ask what they will accept.

Online banks and SSN requirements

Most online banks require an SSN because they cannot verify your identity in person. They rely on SSN verification and credit checks to reduce fraud risk. However, a few online banks have begun offering accounts to people with ITINs, and a smaller number will open accounts without either—though these are rare.

If you are looking for an online account without an SSN, start by calling the bank's customer service line and asking directly. Do not assume the website tells the whole story; policies change and customer service representatives sometimes have more flexibility than the website suggests. Be prepared to open an account in person at a physical branch if the online route does not work.

What happens if you provide false information

Do not provide a fake SSN or someone else's SSN. Banks verify the SSN you give them against Social Security Administration records. If there is a mismatch, the bank will flag it and may close your account. Providing false information to a bank is a federal crime. If you do not have an SSN, tell the bank that directly and ask whether they have an alternative process.

If you are unsure whether your SSN is correct, you can check it yourself. Call the Social Security Administration at 1-800-772-1213 or visit ssa.gov. They can confirm your number and correct any errors in their records before you apply for a bank account.

Frequently Asked Questions

Can I open a checking account with just a passport and no SSN?

Yes, if you find a bank or credit union that does not require an SSN. Bring your passport as your photo ID and a current utility bill or lease as proof of address. Call ahead to confirm the bank will open an account without an SSN, because most will not.

Will a bank accept my ITIN if I do not have a Social Security number?

Some will, but not all. Banks like Banco Popular, BBVA USA, and Wells Fargo have been known to accept ITINs, but policies vary by location. Call your local branch and ask whether they accept ITINs before you visit. Bring the IRS letter that issued your ITIN.

What if ChexSystems says I owe money from a closed account?

You can dispute the record directly with ChexSystems at chexsystems.com. If the debt is yours and unpaid, paying it off may help you open an account elsewhere. Some banks will still work with you even if you have a ChexSystems record; call and ask their policy before you apply.

Can I use someone else's SSN to open a checking account?

No. Banks verify SSNs against Social Security Administration records, and using someone else's number is identity theft and a federal crime. If you do not have an SSN, tell the bank and ask about alternatives like ITIN accounts or no-SSN programs.

Do I need an SSN to add someone else as an authorized user on my account?

That depends on the bank. Some require an SSN or ITIN for all account holders and authorized users; others do not. Ask your bank's policy when you open the account or before you add someone.
