The documents banks require before you can open an account
You need a government-issued photo ID and proof of your current address. That is the baseline. Most banks will also ask for your Social Security number or Individual Taxpayer Identification Number (ITIN), and some will run a check through ChexSystems or Early Warning Services — databases that track banking history and fraud. A few banks have different rules: some accept an ID from another country if you are a non-citizen, and some will open an account with just a passport and no address proof if you are opening online.
The exact documents vary by bank and by whether you are opening in person or online. A bank cannot legally refuse to open an account solely because you lack a Social Security number, but most do require one anyway. If you do not have one, you can still open an account at some banks and credit unions — you will just need to bring more documentation to prove who you are.
Key Takeaways
- A government-issued photo ID and proof of your current address are the two documents nearly every bank requires.
- Your Social Security number or ITIN is standard but not legally required; some banks and credit unions will open accounts without it if you bring additional ID.
- Online account opening usually needs fewer documents than in-person opening, often just a photo ID and a Social Security number.
- Banks check ChexSystems or Early Warning Services to see your banking history; a closed account or fraud flag can slow down or block approval.
Government-issued photo ID: what counts
A driver's license or state ID card is what most banks expect. A passport works too. Some banks also take a military ID, a tribal ID, or a passport card. The ID must not be expired — banks will reject an expired license even if the photo is still recognizable.
If you are a non-citizen without a US driver's license, bring your passport. Some banks will accept a national ID from your home country if it has a photo and an expiration date. Call the bank branch before you go in; policies vary widely on foreign IDs, and some branches will take them while others at the same bank will not.
Proof of current address: what banks accept
A utility bill, lease, mortgage statement, or bank statement dated within the last 60 days is standard. Some banks accept a government document with your address — a tax return, a voter registration card, or a benefits letter from Social Security or unemployment. A few accept mail from a government agency, even if it is not a bill.
The document must show your full name and current address. A cell phone bill usually does not work because banks treat it as a service bill rather than proof of residence. If you are homeless or do not have a current address, some banks and credit unions will let you use a shelter address, a mail forwarding service address, or a trusted contact's address — but you will need to bring a letter from the shelter or a statement from the mail service confirming the address is yours. Call ahead; this is not a standard process and availability depends on the bank.
Social Security number or ITIN
Most banks require a Social Security number (SSN) or an Individual Taxpayer Identification Number (ITIN). The bank uses it to report interest income to the IRS and to check your banking history through ChexSystems. If you do not have an SSN, you can get an ITIN from the IRS — it takes several weeks and requires filing a tax return, even if you do not owe taxes.
You are not legally required to have an SSN to open a checking account. If you do not have one and do not want to get an ITIN, some credit unions and a handful of banks will open an account if you bring additional ID — usually a passport plus two other forms of ID, or a combination of documents that add up to proof of identity. This is rare and not may provide. Call the bank or credit union directly and ask whether they have a process for people without an SSN.
ChexSystems and Early Warning Services checks
When you explore, the bank will check your history in ChexSystems or Early Warning Services. These are databases that record closed accounts, overdrafts, fraud, and other banking problems. A bank can see whether you have unpaid overdrafts at another bank, whether you closed an account under suspicious circumstances, or whether you have a pattern of bounced checks.
A bad ChexSystems record does not automatically disqualify you, but it can delay approval or cause a bank to deny your process. If you have been flagged, you can request your ChexSystems report for free once a year at www.chexsystems.com. If there is an error, you can dispute it. Some banks specialize in second-chance accounts and will open an account even if you have a ChexSystems flag, though they may charge higher fees or require a larger opening deposit.
Online account opening: fewer documents, faster process
Opening online usually requires only a photo ID and a Social Security number. You upload a photo of your ID — front and back — and the bank verifies it electronically. You do not need to bring proof of address; the bank uses your address from the ID or asks you to type it in during the process.
Some online banks skip the ChexSystems check entirely or use a lighter version. This can make online opening faster if you have banking history issues. However, online banks still verify your identity, and they will reject your process if the ID photo does not match your face or if the ID is expired. If you are opening an account at an online bank and you do not have a Social Security number, contact the bank's customer service before you start the process — most online banks do not have a workaround for this the way some in-person banks do.
What to bring if you do not have standard documents
If you do not have a driver's license, bring a passport or state ID card. If you do not have proof of address, bring a lease, a utility bill, or a government letter. If you do not have a Social Security number, bring your passport plus one or two additional forms of ID — a state ID, a tribal ID, a military ID, or a birth certificate. Call the bank first and ask what combination they will take.
If you have been denied at one bank, try a credit union or a second-chance bank. Credit unions often have more flexible rules than large banks, and they may not check ChexSystems at all. Second-chance banks are designed for people with banking history problems and will open an account even if you have overdrafts or fraud flags, though fees are usually higher.
Frequently Asked Questions
Can I open an account with just a passport and no other ID?
Most banks will not. A passport proves who you are, but it does not prove where you live. You need both. Some online banks will take a passport alone if you provide an address during the process, but they will verify that address through other means. Call the bank before you explore.
What if my address on my ID is old?
Bring a second document showing your current address — a utility bill, lease, or bank statement dated within the last 60 days. The bank needs proof that you live where you say you do now, not where you lived when you got your ID.
Will a ChexSystems flag stop me from opening an account?
Not always. Many banks will still open an account if you have a flag, though some may require a larger opening deposit or charge higher fees. Second-chance banks and credit unions are more likely to approve you. Request your ChexSystems report to see what is on it, and dispute any errors before you explore.
Do I need an SSN if I am not a US citizen?
No. You can get an ITIN from the IRS, or you can look for a bank or credit union that will open an account without one. Some banks accept a passport and additional ID instead. Call ahead — this is not a standard process at most banks.
Can I open an account online if I do not have a current address?
Most online banks require an address during the process. If you are homeless or do not have a permanent address, try opening in person at a local bank or credit union instead. Some will let you use a shelter address or a mail forwarding service address if you bring documentation from that organization.
