Most banks require a Social Security number, but alternatives exist
Yes, most banks in the United States require a Social Security number (SSN) to open a checking account. They use it to verify your identity, check your banking history through ChexSystems or Early Warning Services, and report account activity to the IRS. If you have a valid SSN, the bank will ask for it during the process process—either online, by phone, or in person.
If you don't have an SSN, you have options. Some banks and credit unions will open accounts using an Individual Taxpayer Identification Number (ITIN) instead. A few institutions offer checking accounts without any identification number at all, though these come with limits on what you can do with the account. The route you take depends on your immigration status, your state, and which banks operate near you.
Key Takeaways
- Most major banks require an SSN to open a checking account and will use it to verify your identity and check your banking history.
- If you have an ITIN but no SSN, some credit unions and smaller banks will open accounts using the ITIN instead.
- A few banks offer "second chance" or basic checking accounts that require no identification number, though they usually have lower limits and higher fees.
- Some states have laws requiring banks to offer accounts to people without SSNs, so your location matters when looking for alternatives.
Why banks ask for your Social Security number
Banks use your SSN to run a background check through ChexSystems or Early Warning Services. These are banking history databases that track closed accounts, overdrafts, and fraud. The bank wants to know whether you have a history of misusing accounts at other institutions. If you have never had a checking account before, this check will straightforward show no history—which is not a problem.
The SSN also lets the bank verify your identity against government records and report your account activity to the IRS. Banks are required by federal law to report certain transactions and to know who their customers are. Without an SSN, the bank cannot complete these steps using the standard process.
Opening an account with an ITIN instead of an SSN
An Individual Taxpayer Identification Number is a nine-digit number issued by the IRS to people who are not may be able to access for an SSN but need to file taxes or conduct business in the United States. If you have an ITIN, some credit unions and regional banks will use it in place of an SSN to open a checking account.
Credit unions are more likely to accept an ITIN than large national banks. Call ahead and ask whether the institution accepts ITIN applications. You will still need to bring identification—a passport, state ID, or consular ID card—and proof of address, such as a utility bill or lease. The process is otherwise the same as opening an account with an SSN.
Not all banks accept ITINs, and policies vary by state and by individual branch. If you are turned down at one institution, try another. Some states, including California, Illinois, and New York, have laws or agreements encouraging banks to accept ITIN applications, so you may have better luck in those states.
Checking accounts that don't require an identification number
A small number of banks and fintech companies offer checking accounts without requiring an SSN or ITIN. These are sometimes called "second chance" accounts or basic checking accounts. They exist partly because some states have laws requiring banks to offer accounts to unbanked populations, and partly because some companies see a business opportunity in serving people who cannot get traditional accounts.
These accounts come with trade-offs. Limits are usually lower—you might be able to hold only $500 or $1,000 at a time. Monthly fees are often higher than standard checking. You may not be able to use a debit card or may have restrictions on how many transactions you can make per month. Some accounts require you to deposit money in person rather than by transfer. Before opening one, read the fee schedule and terms carefully.
Chime, a fintech company, has historically offered accounts without requiring an SSN, though you will need to provide some form of identification. Some community banks and credit unions in your area may also offer no-ID accounts. Search online for "checking account without SSN" plus your state name, or call local credit unions directly.
What happens if you lie about your SSN
Do not provide a false or borrowed SSN. Banks verify SSNs against Social Security Administration records during the account opening process. If the number does not match a real person or matches someone else, the process will be rejected. If you provide someone else's real SSN, you have committed identity theft, which is a federal crime.
If you are unsure whether you have an SSN, you can check by contacting the Social Security Administration directly. Call 1-800-772-1213 or visit ssa.gov. If you are may be able to access for an SSN but do not have one, you can explore through your local Social Security office.
Opening an account if you are undocumented
If you are undocumented and do not have an SSN or ITIN, your options are narrower but not zero. Some states have passed laws requiring banks to offer accounts to people without SSNs. California, Illinois, New York, and a few others have such laws or have reached agreements with banks to do so. If you live in one of these states, contact your local credit union or community bank and ask whether they offer accounts under these programs.
If your state does not have such a law, look for community banks or credit unions that serve immigrant populations. These institutions sometimes have workarounds or are more willing to take on the compliance burden of serving people without standard identification. Bring a passport or consular ID, proof of address, and be prepared to explain your situation. Some institutions will ask for a tax ID number or will create an internal identifier instead of using an SSN.
What documents you will need to bring
| If you have an SSN | If you have an ITIN | If you have neither |
|---|---|---|
| Valid government ID (driver's license, passport, state ID) | Valid government ID (passport, consular ID, state ID) | Passport or consular ID |
| Proof of address (utility bill, lease, bank statement) | Proof of address (utility bill, lease, bank statement) | Proof of address (utility bill, lease, bank statement) |
| Your SSN | Your ITIN | Varies by institution; call ahead |
Bring originals or certified copies, not photographs. If you are opening the account online, you may be able to upload images of your documents, but the bank will usually ask you to verify them in person or by video call before the account is fully activated.
Frequently Asked Questions
Can I open a checking account with just a passport and no SSN?
Some credit unions and community banks will, especially if you live in a state with laws supporting this. Call ahead to ask. You will also need proof of address. If the bank requires an SSN or ITIN and you do not have one, ask whether they offer accounts under any state programs for unbanked residents.
Will the bank report my account to immigration authorities?
No. Banks are required to report suspicious activity related to money laundering or terrorism financing, but routine account opening and use are not reported to immigration authorities. Your banking information is separate from your immigration status.
What if I have an ITIN but the bank says they don't accept them?
Try another bank or credit union. Policies vary widely. Credit unions are generally more flexible than large national banks. Some states have laws or agreements requiring banks to accept ITINs, so if you live in California, Illinois, New York, or a similar state, you may have better luck at a different branch or institution.
Can I use a fake name or borrowed SSN to open an account?
No. Banks verify SSNs and names against government records. Using a fake name or someone else's SSN is identity theft and is a federal crime. If your process is rejected, explore the legitimate alternatives listed above instead.
Do I need an SSN to use online banking or a debit card?
No. Once the account is open, you can use online banking and a debit card regardless of whether you opened it with an SSN, ITIN, or no ID number. The identification requirement is only for opening the account, not for using it afterward.
