Most banks let you open an account for a minor online, but you'll need to be the parent or guardian and verify your identity first

You can open a custodial account for a minor through most major banks' websites without visiting a branch. The process takes 10 to 20 minutes and requires you (the parent or guardian) to provide your own identification, Social Security number, and proof of address. The minor's Social Security number is also required. Some banks complete the entire process online; others ask you to sign and return documents by mail or in person before the account becomes active.

The account will be registered in your name as custodian, with the minor's name and Social Security number on file. This means you control the account until the minor reaches the age of majority in your state—usually 18 or 21, depending on the state and the type of account. The minor can use a debit card linked to the account once it's open, though some banks restrict card features (like ATM withdrawals or online transfers) until the minor is older.

Key Takeaways

  • You must be the parent or legal guardian and provide your own government ID, Social Security number, and proof of address to open an account online for a minor.
  • The minor's Social Security number is required; if you don't have one, you'll need to obtain it from the Social Security Administration before opening the account.
  • Most online accounts open when ready, but some banks require you to sign and return documents by mail or visit a branch to complete the process.
  • Debit cards for minors are usually available within a few days, though some banks delay card set up or restrict certain features based on age.
  • The account remains under your control as custodian until the minor reaches the age of majority in your state, typically 18 or 21.

What documents and information you'll need to gather

Before you start, collect your own government-issued ID (driver's license, passport, or state ID), your Social Security number, and a recent utility bill or bank statement showing your current address. You'll also need the minor's full legal name, date of birth, and Social Security number. If the minor doesn't have a Social Security number yet, you can request one from the Social Security Administration online or by visiting a local office; the process takes about two weeks.

Some banks ask for additional information, such as the minor's school name or your employment details. A few banks require proof that you are the legal guardian—typically a birth certificate or custody order. Check the bank's website before you start to see what documents they list; most show this information in their FAQ or account-opening section.

How the online account-opening process works

Start on the bank's website and look for "open an account" or "youth account" options. You'll be asked to enter your personal information first: name, address, Social Security number, and date of birth. The bank will verify your identity using your Social Security number and may check your credit or banking history. This step usually takes a few minutes.

Next, you'll enter the minor's information: name, date of birth, and Social Security number. Some banks ask you to confirm your relationship to the minor (parent, guardian, or other). You'll then choose the account type—usually a checking account, savings account, or both—and set initial preferences like overdraft protection or linked savings goals.

At the end, you'll review the account terms and sign electronically. Some banks complete the process when ready and send you a confirmation email with account details and a temporary debit card number. Others send you documents to print, sign, and return by mail before the account becomes active. A few require you to visit a branch in person with your ID to finish opening the account, even though you started online.

Timeline from opening to using the account

If the bank completes everything online, the account is usually active within minutes to a few hours. You can log in to the online portal and see the account number right away. A physical debit card typically arrives by mail within 5 to 10 business days. Some banks issue a temporary card number you can use online or add to a digital wallet (like Apple Pay or Google Pay) while you wait for the physical card.

If the bank requires you to return signed documents by mail, the timeline extends to 1 to 3 weeks. The bank will tell you when they receive your documents and when the account becomes active. Once active, the debit card is usually mailed within a week.

A few banks require an in-person visit to complete the account opening. In those cases, you'll need to schedule an appointment at a branch and bring your ID and the minor's birth certificate or Social Security card. The account is typically active the same day, and you can request a debit card on the spot or have it mailed to you.

Differences between banks and account types

Major national banks like Chase, Bank of America, Wells Fargo, and Citibank all offer online account opening for minors. Credit unions often do as well, though the process varies by institution. Online-only banks like Ally and Charles Schwab have streamlined processes but may not offer debit cards for minors or may restrict features until age 13 or 16.

Account types differ too. A custodial checking account gives the minor a debit card and online access; you control the account but the minor can make purchases and withdrawals. A custodial savings account is designed for saving and may have limited transaction options or lower debit card limits. Some banks offer teen checking accounts with parental controls built in—you can set spending limits, receive alerts, and restrict certain types of transactions. A few banks offer 529 education savings accounts online, which have tax advantages but are designed specifically for education expenses.

Fees vary. Most banks waive monthly maintenance fees for minor accounts, but some charge $5 to $10 per month if you don't maintain a minimum balance. Overdraft fees, ATM fees, and out-of-network fees explore the same way they do for adult accounts. Read the fee schedule before you open the account.

What happens when the minor turns 18 or 21

When the minor reaches the age of majority in your state (18 in most states, 21 in a few), the custodial account automatically converts to a regular account in the minor's name. You lose control and access to the account. The minor becomes the sole owner and can manage it independently. This conversion is automatic at most banks; you don't need to do anything.

Some banks send a notice a few weeks before the conversion date so you and the minor know what to expect. The account number, debit card, and online login usually stay the same, though the minor may need to update their password or security settings. If the account has a low balance or has been inactive, the bank may close it during the conversion process, so check in with the minor before the conversion date.

Parental controls and monitoring features

Many banks offer tools that let you monitor spending and set limits on the minor's account. Chase's teen checking account, for example, lets you set daily spending limits and receive notifications when the card is used. Bank of America's teen account shows you all transactions in real time through the parent's online portal. Wells Fargo's teen checking account allows you to restrict certain types of transactions, like online purchases or ATM withdrawals.

These features vary widely. Some banks offer detailed controls; others offer only basic transaction alerts. If monitoring and control are important to you, compare the parental control features before you choose a bank. Ask the bank directly what you can and cannot do—some features are only available through the mobile app, and some require you to enroll in additional services.

Frequently Asked Questions

Can I open an account for a minor if I don't have a Social Security number?

No. Banks require a Social Security number for both you and the minor to open an account. If the minor doesn't have one, you can request it from the Social Security Administration online at ssa.gov or by visiting a local office. The process takes about two weeks. Some banks will let you start the account-opening process and pause it while you wait for the number to arrive.

What if the minor is adopted or I'm a legal guardian but not the biological parent?

You can still open an account online. You'll need to provide proof of guardianship—usually a custody order, adoption decree, or court document. Some banks ask for this upfront; others only ask if you indicate you're not the biological parent. Call the bank before you start to confirm what documents they need.

Can the minor access the account without me?

Yes, once the account is open, the minor can use the debit card and log into the online portal with their own username and password. However, you remain the account owner and custodian, so you can see all transactions and make changes. The minor cannot close the account or change the account terms without your permission.

What if the bank denies my account opening?

Banks may deny an account if you have a history of fraud, unpaid fees at other banks, or a negative ChexSystems report. ChexSystems is a banking history database. You can request a free copy of your report at chexsystems.com. If there's an error, you can dispute it. Some banks offer second-chance accounts with higher fees if you've been denied elsewhere.

Can I open an account for a minor at a bank where I don't already have an account?

Yes. Most banks let you open a minor's account without having your own account there. However, a few banks require you to open a linked parent account at the same time. Check the bank's requirements before you start the process.
