The minimum documents and information banks require
To open a bank account, you need a government-issued photo ID, proof of your current address, and your Social Security number or Individual Taxpayer Identification Number (ITIN). Most banks will also ask for your date of birth and a phone number. That is the core set. Some banks add a small deposit—often $25 to $100—though many now waive this requirement.
The specific documents vary slightly by bank and account type. A checking account and a savings account may have different requirements. Online banks often need less paperwork than branches because they verify everything digitally. Credit unions sometimes have looser rules if you are a member of their community or employer group.
If you do not have a photo ID, you can sometimes use a combination of documents instead—a utility bill plus a birth certificate, for example. Banks are required to verify your identity under federal law, but they have some flexibility in how they do it. Call the bank before you go in if your situation is unusual.
Key Takeaways
- A valid government photo ID, proof of address, and Social Security number or ITIN are the standard requirements at nearly all banks.
- Many banks no longer require an opening deposit, though some still ask for $25 to $100 to fund the account initially.
- Online banks typically need fewer documents than brick-and-branch locations because they verify identity electronically.
- If you lack a photo ID, you can often combine other documents like utility bills and birth certificates, though policies vary by bank.
- Credit unions may have different rules than traditional banks, especially if you work for or belong to their sponsoring organization.
What counts as proof of address
Proof of address means a recent document showing your name and current street address. A utility bill (electric, gas, water, internet) dated within the last 60 to 90 days works at almost every bank. So does a lease, a mortgage statement, or a property tax bill. Some banks accept a government-issued document like a state ID or driver's license that shows your address, which means you may only need to bring one piece of paper instead of two.
A bank statement from another financial institution counts at some banks but not others. A cell phone bill sometimes works, sometimes does not—call ahead if that is your only option. Post office mail forwarding notices do not count. If you recently moved and your documents still show an old address, bring the new lease or utility bill along with an explanation; most banks will accept this combination.
If you are homeless or living in temporary housing, some banks have workarounds. A letter from a shelter, a social services agency, or even a trusted community member can sometimes substitute for a traditional address document. This varies widely, so contact the bank directly before attempting to open an account.
Why banks ask for a Social Security number
Banks collect your Social Security number (or ITIN if you do not have an SSN) because federal law requires them to verify your identity and report certain account activity to the IRS. This is called Know Your Customer (KYC) compliance. The bank uses your SSN to check you against government databases and to flag suspicious patterns—not to run a credit check or judge your creditworthiness.
If you do not have a Social Security number, an ITIN (issued by the IRS to people who file taxes but are not may be able to access for an SSN) works at most banks. Some banks also accept a passport number or other government ID number in place of an SSN, though this is less common. A few banks have opened accounts for people with neither, but you will need to call and ask; it is not standard.
The bank will not deny you an account based on your credit score or banking history. They may deny you if you have an active fraud case against you, if you owe money to another bank, or if you appear on certain government watchlists. But a low credit score or a closed account from years ago will not stop you.
Opening deposit requirements and minimum balances
Many banks no longer require you to deposit money to open an account. If they do, the amount is usually $25 to $100 for a checking account and $100 to $500 for a savings account. Some banks waive the deposit if you set up direct deposit of your paycheck or if you maintain a certain minimum balance each month.
A minimum balance is different from an opening deposit. A minimum balance is money you must keep in the account at all times to avoid a monthly fee. This might be $500, $1,000, or higher depending on the account type and the bank. If your balance drops below the minimum, the bank charges you a fee—usually $10 to $15 per month. Some accounts have no minimum balance at all.
Online banks and credit unions tend to have lower or no opening deposits and lower minimum balances than large national banks. If you are opening an account with very little money, compare these options first. A bank that charges you $15 a month for falling below a $500 minimum will cost you money faster than you can build savings.
Documents you do not need (and why banks ask anyway)
You do not need a credit card, a job, or a reference from another bank. You do not need to prove your income. You do not need a letter from an employer. Banks sometimes ask for these things, but they cannot require them to open a basic checking or savings account.
Some banks ask for an employment history or income information to determine which account tier to offer you or whether to approve you for overdraft protection. If you are unemployed, retired, or living on benefits, you can say so. The bank may steer you toward a different account type, but they cannot close the door on you for that reason alone.
Banks do sometimes ask about the source of your money—where deposits will come from. This is part of anti-money-laundering compliance, not a judgment call. If you say "Social Security" or "my paycheck" or "my savings," that is the end of it. You do not need documentation unless the bank specifically asks for it in writing.
What happens after you hand over your documents
The bank will verify your identity against government records, usually within minutes if you are opening an account in person or online. They will check your SSN against IRS records and sometimes run a check against ChexSystems, a banking history database that tracks closed accounts and fraud. This is not a credit check and does not affect your credit score.
If everything clears, your account opens immediately. You will receive a debit card in the mail within 5 to 10 business days. You can start using your account right away—you can deposit checks, set up direct deposit, and make transfers even before the card arrives. Online banks may issue a temporary card number you can use immediately.
If the bank cannot verify your identity or if something flags in their system, they will contact you by phone or email. This might mean they need additional documents, or it might mean they cannot open the account. If this happens, ask why and what documents would help. You have the right to know what information triggered the decision.
Special situations: minors, non-citizens, and people without SSNs
A minor (under 18) can open an account, but a parent or guardian must be present and sign the paperwork. The adult becomes a co-owner or authorized user depending on the bank's rules. Some banks allow minors to open their own account at 13 or 14 with parental consent; others require the adult to be the primary account holder.
A non-citizen with a valid visa or passport can open an account. You will need an ITIN if you do not have an SSN. Some banks ask for additional proof of address if your ID is from another country; a lease or utility bill in your name works. A few large banks have tightened their rules around non-citizen accounts, so if you hit a wall at one bank, try a credit union or a smaller regional bank.
If you have never had an SSN and cannot get an ITIN, a very small number of banks will open an account using only your passport number and other identifying documents. This is rare and usually requires you to visit a branch in person. Call ahead and ask directly; do not assume it is impossible.
Frequently Asked Questions
Can I open a bank account online without going to a branch?
Yes. Most online banks and many traditional banks let you open an account entirely online. You upload photos of your ID and proof of address, enter your information, and verify your identity through video or text message. The process usually takes 10 to 15 minutes. You can start using the account the same day, though a physical debit card arrives by mail later.
What if I do not have a current utility bill for proof of address?
A lease, mortgage statement, property tax bill, or government-issued ID with your current address all work. If none of these are available, ask the bank what they will accept. Some take a letter from a landlord, a social services agency, or even a recent bank statement from another institution. Call before you visit so you know what to bring.
Will opening a bank account hurt my credit score?
No. Opening a bank account does not trigger a credit check and does not appear on your credit report. The bank verifies your identity and checks banking history databases, but these do not affect your credit score. Your credit score only changes when you borrow money or miss payments on existing debt.
Can a bank refuse to open an account for me?
Yes, but only for specific reasons: if you cannot verify your identity, if you have an active fraud case, if you owe money to another bank that they are collecting on, or if you appear on certain government watchlists. A low credit score, no job, or past closed accounts will not disqualify you. If a bank refuses, ask why in writing and consider trying a credit union or online bank.
Do I need to deposit money on the day I open the account?
Not necessarily. Many banks no longer require an opening deposit. If one does, it is usually $25 to $100. You can often deposit this amount by check, transfer, or cash on the same day you open the account. Some banks let you fund the account online after you open it, so you do not have to bring cash to the branch.
