Yes, minors can get debit cards, but the account must be opened and managed by a parent or guardian

A minor cannot open a debit card account on their own. Banks and credit unions require the account holder to be at least 18 years old to sign a contract. What a parent or guardian can do instead is open a custodial checking account—a real bank account with a debit card attached—where the adult maintains legal control while the child uses the card to make purchases and withdraw cash.

The debit card itself works exactly like an adult's card: it draws money directly from the account balance, teaches spending limits because the child can only spend what is there, and builds familiarity with how banking works. The difference is in who owns the account and who can make decisions about it. The parent can set spending limits, monitor transactions, freeze the card, or close the account at any time.

The age at which a child can have a debit card varies by bank. Some institutions offer cards to children as young as 6 or 7; others wait until age 13. A few banks allow teenagers to transition to their own account at 16 or 17 without parental co-ownership, though this is less common. Check with your bank directly about their minimum age and what documentation they require.

Key Takeaways

  • A parent or guardian must open and own the account; the minor cannot open it alone.
  • Custodial checking accounts come with debit cards that teach spending discipline because the child can only spend available funds.
  • Minimum age requirements vary by bank, ranging from age 6 or 7 to age 13, so you will need to contact your bank to confirm.
  • Parents can monitor all transactions, set spending limits, and control the card without the child's permission.
  • Some banks allow teenagers to take over the account at 16 or 17, converting it to a standard account in their name alone.

How custodial accounts work in practice

When you open a custodial checking account at a bank or credit union, you provide your identification and sign the account agreement. The account is legally yours, but it is designated as being for the benefit of your child. You receive a debit card in your name and a debit card in your child's name, both connected to the same account balance.

Money in the account belongs to your child, but you control how it is spent. You can deposit funds, set up automatic transfers, and review every transaction online or through the bank's app. Most banks let you set daily spending limits on the child's card—for example, limiting purchases to $20 per day or $100 per week. Some banks also let you block certain types of transactions, such as online purchases or ATM withdrawals.

Your child can use the card at stores, restaurants, and ATMs just like anyone else. The card will be declined if there is not enough money in the account or if the transaction exceeds the limit you set. This creates a natural boundary: the child learns that money runs out and that spending has consequences.

What to look for when choosing a bank

Not all banks offer custodial accounts, and the features vary widely. Before opening an account, compare what each bank provides. Some key differences include the minimum age, whether there is a monthly fee, whether the account earns interest, and what parental controls are available through the app or online banking.

Many online banks and credit unions offer custodial accounts with no monthly fee, which is better than accounts that charge $5 to $15 per month. Some accounts are free only if you meet certain conditions—for example, if you set up direct deposit or maintain a minimum balance. Read the fee schedule carefully.

Check whether the bank's app lets you set spending limits and view transactions in real time. Some banks show you a detailed breakdown of where your child is spending money; others show only basic transaction history. If teaching your child about budgeting is part of your goal, an app with good visibility and control features will help.

Also confirm the age at which your child can transition to their own account. Some banks automatically convert the account when the child turns 18; others require you to close the custodial account and open a new one. A few banks let teenagers take over earlier, which can be useful if your child is working and wants more independence.

Debit cards versus prepaid cards for minors

A custodial debit card is different from a prepaid card, though both limit spending to available funds. A debit card is connected to a real bank account that you control. A prepaid card is loaded with a set amount of money and works more like a gift card—once the balance is gone, the card stops working until you add more money.

Prepaid cards can be useful if you want to give your child a fixed allowance without access to the full account. However, prepaid cards often charge fees for loading money, checking the balance, or making ATM withdrawals. They also do not build a banking relationship or teach your child how a real checking account works. A custodial debit card is usually the better choice if your goal is financial education.

Teaching your child to use the card responsibly

Having a debit card is a tool for learning, not a substitute for conversation. Before giving your child the card, talk about what it is for. Is it for everyday purchases like lunch at school? For saving toward a goal? For learning to manage money? Be clear about what you expect.

Set a spending limit that matches your child's age and maturity. A 10-year-old might have a $5 daily limit; a 15-year-old might have $50 per week. The limit should be low enough that mistakes do not hurt, but high enough that the card feels useful.

Review transactions together regularly—weekly for younger children, monthly for teenagers. Ask your child why they made certain purchases. This turns the card into a teaching moment rather than just a way to spend money. Over time, your child learns to think about spending decisions before making them.

What happens when your child turns 18

At age 18, your child becomes a legal adult and can open their own bank account. Most banks will convert a custodial account to a standard account in your child's name alone, though the process varies. Some banks do this automatically on the child's 18th birthday; others require you to visit a branch or call to request the conversion.

After the conversion, you no longer have access to the account or the ability to monitor transactions. Your child can change the PIN, set their own limits, and make all decisions about the account. If you want to maintain visibility into your child's finances after 18, that is a conversation to have before the birthday arrives.

If your bank does not offer automatic conversion, you may need to close the custodial account and help your child open a new account in their name. This is a good time to discuss banking basics—overdraft fees, how to avoid them, and what to do if the card is lost or stolen.

Frequently Asked Questions

Can my child use the debit card online or just in stores?

Most custodial debit cards work online and in stores, just like adult cards. However, some banks restrict online purchases by default and require you to enable them through the app. Check your bank's settings to see what your child's card can do. Some parents disable online purchases to reduce the risk of unauthorized spending.

What happens if my child loses the debit card?

Contact your bank immediately to report the card lost or stolen. The bank will freeze the card so no one else can use it, and you can request a replacement card. Most banks send a new card within 5 to 10 business days. In the meantime, your child can still access the account through an ATM if they know the PIN, or you can withdraw cash for them.

Does a custodial debit card build credit?

No. Debit cards do not report to credit bureaus and do not build a credit history. They only teach spending discipline. If your goal is to help your child build credit later, a custodial debit card is a good first step, but they will need a credit card or other credit product as a teenager or young adult to actually build a credit score.

Can I set up automatic allowance deposits to the account?

Yes. Most banks let you set up automatic transfers from your account to your child's account on a schedule you choose—weekly, biweekly, or monthly. This teaches your child to budget around a regular income and removes the need for you to hand over cash or make manual transfers each week.

What if my child spends more than the limit I set?

The card will be declined. The transaction will not go through, and your child will not be able to complete the purchase. This is the main advantage of a debit card over a credit card—your child cannot overspend or go into debt. If your child regularly tries to exceed the limit, it is a sign that the limit is too low or that you need to discuss spending priorities together.
