The Real Age Requirements for Opening a Bank Account

You can open a bank account at any age, but the account structure changes based on how old you are

There is no legal minimum age to have a bank account. A newborn can have one. What changes is who controls the account and what they can do with it. A child under 18 cannot sign a contract, so a parent or guardian must open and manage the account on their behalf. Once you turn 18, you can open and control your own account without anyone else's permission or involvement.

The practical difference matters. Until you turn 18, the adult on the account can see all transactions, freeze the account, or withdraw money. At 18, you become the sole owner and decision-maker. Some banks let you transition from a youth account to a standard account automatically on your birthday; others require you to open a new one.

Key Takeaways

A parent or guardian must open and own a custodial account for anyone under 18, though some banks let teenagers co-own accounts at younger ages.
The adult on a custodial account has full access to the money and transaction history until the account converts or closes.
At 18, you can open your own account without parental involvement, and many banks will convert your youth account to a standard one automatically.
Different banks set different minimum ages for youth accounts—some start at birth, others at age 13—so the age requirement depends on which bank you choose.
You will need an ID to open an account at 18; before that, your parent's ID and your birth certificate or Social Security card usually suffice.

Custodial accounts for children under 18

A custodial account is a bank account owned by a minor but controlled by an adult. The parent or legal guardian opens it, provides their own ID and Social Security number, and the child's name goes on the account as the beneficiary. The adult is the account owner in the bank's records and has complete access to the funds and transaction history.

Banks do not require the child to be present to open a custodial account, though some ask for the child's Social Security number or birth certificate as proof of identity. You can open one for a newborn if you want to start saving for them. The account works like any other checking or savings account—you can deposit money, set up direct deposit, and use a debit card if the bank offers one for that account type.

The adult controls the account until the child turns 18 or until the account is formally transferred. At that point, the child becomes the sole owner. Some banks do this automatically; others require a visit or a form. Check with your bank about what happens on your 18th birthday.

Youth accounts and teen accounts for ages 13 and up

Many banks offer youth accounts or teen accounts starting at age 13, though some begin at age 10 or 16. These accounts are still custodial—a parent or guardian must open them and remains the account owner—but they come with features designed for teenagers: lower or no monthly fees, no minimum balance, and sometimes a debit card the teen can use independently.

The key difference from a standard custodial account is the debit card and the messaging around independence. A teen account might let a 15-year-old use the card to buy things and check their balance on a mobile app, while the parent still sees all transactions and can freeze the card if needed. The parent remains the legal owner and can withdraw money or close the account.

Youth accounts typically convert to standard adult accounts automatically when you turn 18, though the exact age varies by bank. Some convert at 18, others at 21. Ask your bank what age triggers the conversion and whether you need to do anything to make it happen.

What you need to open an account before age 18

To open a custodial or youth account, the adult needs to bring their own government-issued ID (driver's license, passport, or state ID) and provide their Social Security number. The bank will also ask for the child's name, date of birth, and usually their Social Security number or tax ID. Some banks ask for a birth certificate or other proof of the child's identity, though not all do.

You do not need the child present. Many parents open accounts for their children without them ever visiting the bank. If the bank offers a debit card for the account, the child may need to visit in person to pick it up and set a PIN, depending on the bank's policy.

Opening your own account at 18

At 18, you can walk into a bank or open an account online without a parent or guardian. You will need a government-issued ID (driver's license, passport, or state ID) and your Social Security number. Some banks also ask for a second form of ID or proof of address, such as a utility bill or lease.

If you already have a youth account, you do not have to open a new one. Most banks convert the account automatically and send you a new debit card and checks in your name alone. If your bank does not convert automatically, you can ask them to transfer the money to a new adult account, or you can straightforward stop using the youth account and open a fresh one elsewhere.

Online banks have the same requirements as brick-and-mortar banks: a valid ID and Social Security number. The process takes a few minutes, and your account is usually active the same day or within one business day.

What happens if you turn 18 with a custodial account

The account does not automatically become yours just because you turn 18. The parent or guardian remains the owner unless they take steps to change that. Some banks have automatic conversion policies that trigger on your 18th birthday—the account switches to your name alone, and the parent is removed. Others require the parent to visit the bank or sign a form to make the transfer official.

If your bank does not convert automatically and your parent does not initiate the transfer, you will still be on a custodial account with your parent as the owner. You can ask your parent to contact the bank and request the conversion, or you can open a separate adult account at the same bank or a different one and transfer your money over.

If there is a conflict—for example, your parent refuses to convert the account or remove themselves—you have the right to open your own account at 18 without their involvement. You cannot force them to close or convert the existing account, but you can stop using it and move your money elsewhere.

Age requirements vary by bank

There is no federal law setting a minimum age for bank accounts, so each bank sets its own rules. Most major banks allow custodial accounts from birth. Youth or teen accounts typically start at age 13, but some banks begin at 10, and others wait until 16. A few banks do not offer youth accounts at all and require you to wait until 18 to open an account in your own name.

If you are under 13 and want to open an account, check with banks in your area or online banks to see which ones allow custodial accounts for younger children. If you are 13 or older, you have more options: most major banks and many online banks offer youth accounts at that age.

Frequently Asked Questions

Can a 10-year-old open a bank account?

A 10-year-old cannot open an account alone, but a parent or guardian can open a custodial account for them at most banks. Some banks allow custodial accounts from birth; others have a minimum age of 13. Call your bank or check their website to see if they offer accounts for children under 13.

What happens to a youth account when I turn 18?

Most banks automatically convert youth accounts to standard adult accounts on your 18th birthday, removing the parent as the account owner. Some banks require the parent to sign a form or visit the bank to make the conversion official. Contact your bank to find out their specific process and timeline.

Can I have a bank account without my parents knowing?

At 18, yes—you can open an account on your own without telling anyone. Before 18, a parent or guardian must open and own the account, so they will be involved. If you are under 18 and want privacy, talk to your parent about opening a youth account where you control the debit card and transactions, even though they remain the account owner.

Do I need a Social Security number to open a bank account?

Most banks require a Social Security number or tax ID to open any account, including custodial accounts. If you do not have a Social Security number, some banks will accept an Individual Taxpayer Identification Number (ITIN) instead. Call ahead to confirm what your bank accepts.

Can I move money from a custodial account to my own account at 18?

Yes. Once you turn 18 and open your own account, you can transfer money from the custodial account to your new account. You can do this online, by visiting the bank, or by asking the parent to initiate the transfer. There is no law preventing you from moving your own money once you are an adult.
