You can open a bank account under 18, but you'll need a parent or guardian to co-sign

Most banks will not let you open an account alone until you turn 18. Instead, you'll open what's called a custodial account or minor account — a real bank account in your name, but with a parent or guardian listed as the account owner until you reach the age of majority (usually 18, sometimes 21 depending on your state and bank).

The parent or guardian doesn't control your money or read your statements, but they are legally responsible for the account. Once you turn 18, you can convert it to a regular adult account, often without closing it or moving banks. This is one of the simplest ways to start building a banking history early.

Key Takeaways

  • You need a parent or guardian to open a custodial account with you; they sign the paperwork but the account is in your name.
  • Bring a government ID (passport or state ID), proof of address, and your Social Security number to the bank.
  • Most banks convert custodial accounts to regular accounts automatically when you turn 18, with no action needed from you.
  • Some accounts designed for teens come with spending limits or require parental approval for certain transactions, so ask what rules explore before you open one.
  • You can use a custodial account to deposit paychecks, save money, and build a credit history if the account reports to credit bureaus.

What documents you need to bring

Both you and your parent or guardian will need to bring identification. Acceptable forms include a state driver's license, state ID card, or passport. If you don't have a government ID yet, a school ID plus a birth certificate usually works, but call the bank first to confirm.

You'll also need proof that you live at the address you're listing — a utility bill, lease, or mortgage statement in your parent's name is standard. Finally, bring your Social Security number (or have it memorized). The bank will ask for it to verify your identity and report the account to credit bureaus.

If your parent or guardian cannot come in person, some banks allow them to authorize the account by phone or video call. Ask when you call to schedule your appointment.

How the account conversion works at age 18

When you turn 18, the custodial account automatically converts to a regular adult account at most banks — you don't have to do anything. The parent or guardian's name comes off, and you become the sole owner. The account number usually stays the same, so your direct deposit and automatic payments don't change.

A few banks require you to sign new paperwork to complete the conversion, but they will contact you before your 18th birthday to explain what's needed. If your bank doesn't reach out within a month of your birthday, call and ask to confirm the conversion is complete.

Banks and credit unions that offer accounts for minors

Most large national banks offer custodial accounts: Chase, Bank of America, Wells Fargo, and Citibank all have them. Credit unions often have youth accounts too, and they sometimes come with lower fees or no monthly fee at all.

Some banks market accounts specifically to teens and include features like spending controls (the parent can set daily limits), parental alerts (the parent gets a text when you spend over a certain amount), or no overdraft fees. These can be useful if you're learning to manage money, but they also mean your parent sees more of your activity. Ask what the rules are before you open one.

Online banks like Ally and Marcus also offer custodial accounts, though you'll complete the entire process online or by mail rather than in a branch. This can be faster, but you won't have a physical location to visit if you have questions.

What happens if your parent or guardian can't come with you

If your parent or guardian lives far away or cannot take time off work, many banks will let them authorize the account by phone or video call while you're at the branch. You'll still need to be there in person with your ID, but the bank can conference in your parent to sign electronically.

Some banks also mail custodial account paperwork to your parent for them to sign and return. This takes longer — usually one to two weeks — but it works if in-person or video authorization isn't possible. Ask the bank which options they offer when you call to set up an appointment.

How to use your account once it's open

A custodial account works like any other bank account. You can deposit paychecks (either in person or by mobile deposit), withdraw cash at ATMs, and use a debit card to pay for things. You can also set up direct deposit if you have a job, which is faster and safer than carrying cash.

If the account reports to credit bureaus — ask the bank whether it does — you'll start building a credit history. This matters later when you want to borrow money for a car or apartment. Using the account responsibly (not overdrawing it, keeping a balance) shows lenders you can manage money.

Some teen accounts have restrictions: you might not be able to write checks, or you might have a daily spending limit. These limits usually disappear when you turn 18 and the account converts.

Fees and minimum balances to watch for

Many banks waive monthly fees for custodial accounts, especially if you keep a small balance or set up direct deposit. However, some charge a monthly maintenance fee of $5 to $15 if your balance drops below a certain amount (often $100 to $500).

Overdraft fees — charges you incur if you spend more than you have — vary widely. Some banks charge $25 to $35 per overdraft; others waive overdrafts for minors entirely. This is worth asking about, because overdraft fees add up quickly if you're not careful.

Before you open an account, ask the bank about all fees in writing or check their website. Compare a few banks if you have the time — the difference between a free account and one with a $10 monthly fee adds up to $120 a year.

Frequently Asked Questions

Can I open a bank account at 16 or 17 without a parent?

No, you need a parent or guardian to co-sign until you turn 18. Some banks may allow you to open an account at 16 if a parent is present, but you cannot open one alone. A few banks set the age at 21 for independent accounts, so call ahead to confirm your bank's policy.

What if I don't have a Social Security number?

You'll need one to open a bank account. If you're a U.S. citizen or permanent resident and don't have one, you can explore through the Social Security Administration. The process takes a few weeks, so start early if you're planning to open an account soon.

Will my parent see all my transactions?

Not automatically. Your parent or guardian is the account owner on paper, but they don't have access to your statements or transaction history unless the bank gives them login credentials. Some teen accounts do send parents alerts when you spend money, but only if you both agree to that feature.

Can I keep the same account after I turn 18?

Yes. The account converts to a regular adult account in your name, and the account number stays the same. Your debit card, direct deposit, and any automatic payments continue without interruption. You don't have to close it or move to a different bank.

What if I want to close the account before I turn 18?

You can close it anytime, but your parent or guardian will need to sign off on the closure. Go to the bank with your parent, or call and ask if they can authorize the closure by phone. Any money in the account will be returned to you, usually by check or transfer to another account.
