You cannot open a credit card in your child's name without their consent, but you have other options that build credit
A credit card issued solely in your child's name requires their signature and a Social Security number, which means you cannot legally open one for a minor without their knowledge. However, you can add them to your own account as an authorized user, which reports to their credit history. You can also wait until they turn 18 and help them open their first card, or explore secured credit cards designed for young adults with no credit history.
The distinction matters because each path affects your child's credit differently and carries different legal and financial responsibilities. Understanding what is actually available helps you choose the approach that fits your family's situation and your child's age.
Key Takeaways
- You can add your child as an authorized user to your existing credit card, which reports account history to their credit file even though they cannot use the card independently.
- A minor cannot sign a legal contract, so opening a card in their name alone is not possible until they turn 18.
- Authorized user accounts report to the three major credit bureaus (Equifax, Experian, and TransUnion) and can help build credit before your child applies for their own card.
- When your child turns 18, they can open a secured credit card or become a joint account holder on your card, giving them more control over their own credit.
- Your payment history on the account affects your child's credit score, so missed payments or high balances will harm their credit even if they never use the card.
How authorized user accounts work and what they report
When you add your child as an authorized user, the credit card company issues them a card with their name on it, but the account remains in your name and under your legal responsibility. You make all payments, set all limits, and control all activity. The account history—including the credit limit, payment history, and balance—reports to your child's credit file at the three major credit bureaus.
This means your child builds a credit history without having signed any contract or taken on any legal obligation. If you pay on time and keep the balance low, their credit score rises. If you miss payments or carry a high balance, their score falls. The card issuer does not verify that your child actually uses the card; they straightforward report the account to their credit file because they are listed as an authorized user.
Not all card issuers report authorized user accounts to the credit bureaus, so check with your card company before adding your child. Most major issuers (Chase, American Express, Capital One, Discover, Citi) do report these accounts, but some smaller banks and credit unions do not. If the account does not report, it will not build your child's credit.
The age requirement and when your child can use the card
There is no legal minimum age to be an authorized user. Some card issuers set their own minimums (often age 13 or 16), but many have no age restriction at all. You can add a child of any age to your account if the issuer allows it.
However, being an authorized user does not mean your child can legally use the card. A minor cannot enter into a contract with a merchant, so technically they should not be making purchases. In practice, many parents give their authorized user children a card to use for specific purposes (groceries, gas, school supplies) and monitor the spending. Others keep the card in their own wallet and use it only to build the child's credit history without letting them spend.
The card issuer does not enforce how the card is used—that is between you and your child. But you remain legally and financially responsible for all charges, regardless of who made them.
What happens to your child's credit when you remove them
If you remove your child as an authorized user, the account stops reporting to their credit file. The history of that account may remain on their credit report for up to seven years (depending on whether the account was in good standing), but new activity will not be added.
This matters if you are using an authorized user account as a stepping stone to your child's own card. If you remove them right before they turn 18, they lose the benefit of that account history when they explore for their first card in their own name. If you keep them on the account, the positive history continues to help their credit score.
Some parents remove their child as an authorized user if the child's own credit score becomes strong enough, or if the parent's financial situation changes and they want to limit the child's exposure to their account. There is no penalty for removing an authorized user, but the timing affects how much credit-building benefit your child receives.
Opening a card in your child's name once they turn 18
At 18, your child can sign a contract and open a credit card in their own name. If they have been an authorized user on your account for several years, they will have an established credit history and a credit score, which makes approval easier and may may have access to them for better terms.
If they have no credit history, a secured credit card is often the easiest first option. Secured cards require a cash deposit (usually $200 to $2,500) that serves as collateral and becomes the credit limit. The card reports to all three credit bureaus, and after 6 to 18 months of on-time payments, many issuers convert it to a regular unsecured card and return the deposit.
Your child can also become a joint account holder on your existing card at 18, which gives them full legal responsibility for the account alongside you. This is different from being an authorized user because both of you can make charges and both of you are liable for the debt. This option makes sense if your child is ready to share financial responsibility, but it carries more risk than the authorized user route.
The risks of authorized user accounts for your credit
Adding your child as an authorized user does not affect your credit score directly, but the account itself does. If you already have high balances or a history of missed payments on this card, adding your child exposes them to that negative history. They inherit the account's entire payment record, not just the positive parts.
If you later miss a payment or let the balance grow, your child's credit score drops along with yours. This is why authorized user accounts work best when you have strong payment habits and low balances. If your finances are unstable, the authorized user route may harm your child's credit rather than help it.
You also cannot remove negative history from your child's credit report by removing them as an authorized user. If the account had missed payments while they were on it, that history stays on their report for seven years. This is another reason to use an account with a clean payment record.
Alternatives if you cannot add your child to your own card
If you do not have a credit card, or if your card issuer does not allow authorized users, you have other options. A credit-builder loan from a credit union or online lender lets your child borrow a small amount (usually $500 to $1,000) and repay it over time. The lender reports the payments to the credit bureaus, building credit history without requiring an existing credit score.
You can also co-sign a credit card process when your child turns 18. As a co-signer, you are legally responsible for the debt if your child does not pay, but your child owns the account and builds their own credit history. This is riskier than the authorized user route because you are liable for the full balance, not just monitoring an account you control.
Some parents open a joint savings account with their child and teach them to manage money before moving to credit products. This builds financial habits without credit risk, though it does not build a credit score.
Frequently Asked Questions
Will adding my child as an authorized user hurt my credit score?
No. Adding an authorized user does not change your credit score. The account itself already affects your score based on your payment history and balance, but adding your child's name to it does not make that impact worse or better.
Can my child use the authorized user card without my permission?
Legally, no—a minor cannot enter into a contract with a merchant. In practice, if you give them the card, they can swipe it. You remain responsible for all charges. Many parents keep the card in their own wallet and use it only to build the child's credit history.
What age should I add my child as an authorized user?
There is no legal minimum, though card issuers may set their own (often 13 or 16). The earlier you add them, the longer their credit history grows before they turn 18. Adding them at 13 or 14 gives them several years of history by the time they explore for their own card.
Does my child need a Social Security number to be an authorized user?
Most card issuers require a Social Security number to add someone as an authorized user, though some may accept an Individual Taxpayer Identification Number (ITIN). Check with your card issuer about their specific requirements.
What happens to my child's credit if I miss a payment?
Missed payments on the account report to your child's credit file and lower their credit score, even though they did not make the purchase or miss the payment themselves. This is why authorized user accounts only help credit if you maintain strong payment habits.
