Yes, you can open a bank account the day you turn 18
You become a legal adult at 18, which means you can sign contracts and open financial accounts without a parent or guardian's permission. Most banks will open a checking or savings account for you on your 18th birthday itself, though the exact process depends on whether you walk into a branch, apply online, or use a mobile app.
The main requirement is a valid government-issued ID — a driver's license, state ID card, or passport. You will also need a Social Security number or Individual Taxpayer Identification Number (ITIN). Some banks ask for a second form of ID or proof of address, like a utility bill or lease, but many waive this for customers opening accounts in person at a branch.
If you have been a minor on a joint account with a parent, that account does not automatically convert when you turn 18. You can keep it as is, convert it to an account in your name alone, or open a separate account. Talk to your bank about what happens next.
Key Takeaways
- You can open a bank account on your 18th birthday with a valid government ID and Social Security number.
- Opening in person at a branch is usually fastest and requires the fewest documents.
- Online and mobile apps may take one to three business days to verify your identity and activate your account.
- If you have a minor account with a parent, you will need to decide whether to keep it, convert it, or open a new account.
- Some banks offer accounts designed for young adults with lower fees or no minimum balance requirements.
Opening an account in person versus online
Walking into a branch on your 18th birthday is the fastest route. Bring your ID and Social Security number, and a banker can open your account in 15 to 30 minutes. You will leave with a debit card (though it may take five to seven business days to arrive by mail) and immediate access to your account number so you can start receiving direct deposits or transfers that same day.
Opening online or through a mobile app takes longer because the bank has to verify your identity remotely. Most banks use a combination of questions about your credit history, a video call where you show your ID to a representative, or a process where you photograph your ID and answer security questions. This verification usually takes one to three business days. Your account will be active before your debit card arrives.
Online accounts often have lower or no monthly fees, no minimum balance requirements, and higher interest rates on savings. In-person accounts may have more features like access to a physical branch network, but fees and minimums vary widely by bank. Compare what each bank offers before you decide.
What happens to a joint account when you turn 18
If you have been on a checking or savings account with a parent since you were younger, that account does not automatically change on your 18th birthday. Your parent remains the account owner and can still see all transactions, withdraw money, and close the account. You have no legal ownership of the money in it.
You have three options: keep the account as is (useful if your parent helps manage your money), ask your parent to convert it to an account in your name alone, or open a new account in your name only. If you convert the existing account, your parent will no longer have access to it. If you open a new account, you can transfer your money to it yourself or ask your parent to send it.
Some banks make conversion simple — a visit to a branch or a phone call can do it. Others require you to close the old account and open a new one. Call your bank before your birthday to ask what the process is and whether any fees apply.
Documents and information you will need
Bring a valid government-issued photo ID: a driver's license, state ID card, or U.S. passport. If you are opening an account in person, this is usually all you need. If you are opening online, you may need to photograph both sides of your ID and verify it matches your face through a video call or selfie.
You will need your Social Security number. If you do not have one, you can apply for one at your local Social Security office — the process takes about two weeks. Some banks will not open an account without a Social Security number, though a few accept an ITIN (Individual Taxpayer Identification Number) if you are not a U.S. citizen.
A few banks ask for proof of address, such as a utility bill, lease, or mail from a government agency. If you live with your parents and do not have mail in your name, ask the bank whether a parent's bill with your name on it counts, or whether you can use a school ID or other document instead.
Debit cards, PINs, and first transactions
When you open your account, the bank will issue you a debit card. If you open in person, you may receive a temporary card on the spot or a card number you can use immediately online and in stores. Your permanent card will arrive by mail in five to seven business days.
If you open online, your debit card will be mailed to you after your account is activated, usually within one to two weeks. In the meantime, you can use your account number and routing number to set up direct deposit or receive transfers from others. Some banks let you add your account to a digital wallet (Apple Pay, Google Pay, Samsung Pay) before your physical card arrives.
You will choose a PIN (personal identification number) for ATM withdrawals. Write it down somewhere safe, not on the card itself. Your debit card can be used at any ATM in your bank's network for free; using an out-of-network ATM usually costs $2 to $3 per transaction.
Banks that welcome new account holders at 18
Most major banks — Chase, Bank of America, Wells Fargo, Citibank, and regional banks — will open accounts for 18-year-olds. Credit unions also open accounts for new members at 18. Online banks like Ally, Charles Schwab, and Discover have no physical branches but often have lower fees and higher savings rates.
Some banks offer accounts designed for young adults, with perks like no monthly fees, no minimum balance, and no overdraft fees if you link a savings account. Chase has the Chase Secure Banking account; Bank of America has the Advantage SafeBalance Banking account; and many credit unions have student or young adult accounts. These accounts sometimes convert to standard accounts after a certain age or after you meet certain conditions.
Before you open an account, check the bank's website or call to confirm the minimum age is 18 and what documents you will need. If you have questions about fees, minimum balances, or interest rates, ask — banks are required to disclose this information, and it varies by account type and location.
What to do if you do not have a Social Security number yet
If you turned 18 but do not have a Social Security number, apply for one at your local Social Security office or online at ssa.gov. You will need your birth certificate, proof of citizenship or immigration status, and a state-issued ID. The process takes about two weeks by mail or one to two weeks if you apply in person.
While you wait, you cannot open most bank accounts. A few banks and credit unions accept an ITIN (Individual Taxpayer Identification Number) instead, which you can get from the IRS if you are not a U.S. citizen. Call banks in your area to ask which ones accept ITINs before you apply.
If you are a permanent resident or have a work visa, you may be able to open an account with your green card or visa plus a passport. Ask the bank directly — policies vary.
Frequently Asked Questions
Can I open a bank account online on my 18th birthday?
Yes. Most online banks will let you start the process on your birthday, but account activation usually takes one to three business days for identity verification. You can use your account number for transfers and direct deposits before your debit card arrives.
What if I do not have a driver's license?
A state ID card or U.S. passport works just as well. If you do not have any of these, you can get a state ID card at your DMV — bring your birth certificate, Social Security card, and proof of address. This takes a few days to a few weeks depending on your state.
Can my parent still access my account after I turn 18?
Only if you keep them on the account. If you open a new account in your name alone or convert your joint account to your name only, your parent will have no access. If you want them to help manage your money, you can add them as an authorized user or keep a joint account.
Do I need a minimum balance to open an account?
Most banks do not require a minimum balance to open an account, though some charge a monthly fee if your balance drops below a certain amount. Online banks and accounts for young adults often have no minimum balance and no monthly fees. Check the bank's fee schedule before you open.
How long does it take to receive my debit card?
If you open in person, you may get a temporary card immediately or a card number to use right away. Your permanent card arrives by mail in five to seven business days. If you open online, your card usually arrives within one to two weeks after your account is activated.
