What teenagers need to know before getting a credit card

Teenagers under 18 cannot get a credit card in their own name. Federal law requires cardholders to be at least 18 years old and have an independent income that the issuer can verify. Before that age, a teenager's options are limited to becoming an authorized user on a parent's card, opening a teen checking account with a debit card, or using a secured credit card once they turn 18.

The reason for the age requirement is that credit card companies need someone legally responsible for the debt. A parent or guardian can add a teenager to their account as an authorized user, which means the teenager gets a card linked to that account but the parent remains liable for all charges. This approach builds credit history without requiring the teenager to may have access to on their own.

Starting early matters because credit history takes time to build. A teenager who becomes an authorized user at 16 will have several years of payment history by the time they explore for their first independent card at 18 or 19. That history can mean lower interest rates and better terms than someone starting from zero.

Key Takeaways

  • Teenagers under 18 cannot hold a credit card in their own name, but can become authorized users on a parent's account to start building credit history.
  • Authorized user accounts report to credit bureaus, so on-time payments help the teenager's credit score even though the parent is legally responsible for the debt.
  • At 18, teenagers can explore for their own secured credit card, which requires a cash deposit but reports to credit bureaus like a regular card.
  • Debit cards and prepaid cards do not build credit history because they do not report to credit bureaus.
  • The goal before age 18 is to demonstrate responsible money habits so that independent credit applications at 18 or 19 are more likely to be approved.

How authorized user accounts work

When a parent adds a teenager as an authorized user, the teenager receives a card with their name on it but linked to the parent's account. The parent controls the account, sets spending limits (if the card issuer allows), and receives all the bills. The teenager can make purchases, but the parent is legally responsible for paying the balance.

Most credit card issuers report authorized user accounts to the three major credit bureaus: Equifax, Experian, and TransUnion. This means the teenager's credit file begins to build as soon as the account is opened. If the parent makes on-time payments, the teenager's credit score benefits. If the parent misses payments or carries high balances, the teenager's score is damaged.

The teenager has no control over whether the account is paid on time or how much is charged. This is both a strength and a risk. The strength is that the teenager benefits from the parent's good credit habits without having to manage the account themselves. The risk is that if the parent's finances deteriorate, the teenager's credit score suffers even though they made no decisions about the account.

Some issuers allow parents to set spending limits for authorized users, and a few offer separate statements or alerts so the teenager can track their own charges. Chase, American Express, and Discover offer some form of spending controls or monitoring. Check with your card issuer about what options are available.

Secured credit cards for teenagers turning 18

A secured credit card is designed for people with no credit history or poor credit. The cardholder deposits cash into a savings account held by the card issuer, and that deposit becomes the credit limit. A teenager with $500 in the deposit account gets a $500 credit limit. The deposit stays in the account; the teenager uses the card to make purchases and pays the bill each month, just like a regular credit card.

Secured cards report to credit bureaus, so on-time payments build credit history. After 6 to 18 months of responsible use, many issuers will convert the account to a regular unsecured card and return the deposit. Some teenagers graduate to a better card with rewards or lower fees once their credit score improves.

The main cost is the deposit itself, which is money the teenager cannot access while it secures the card. Some issuers also charge an annual fee, typically $25 to $50. Interest rates on secured cards are usually higher than on regular cards—often 18% to 22%—because the issuer sees the cardholder as higher risk. The goal is to pay the full balance each month so interest charges do not accumulate.

Issuers that offer secured cards to teenagers include Capital One, Discover, and U.S. Bank. Each has different deposit requirements, fees, and conversion timelines. A teenager should compare these before choosing, because the terms affect how quickly credit history builds and how much the card costs.

Debit cards and prepaid cards do not build credit

A debit card draws directly from a checking account and does not create debt. A prepaid card is loaded with cash in advance and works like a debit card. Neither one reports to credit bureaus, so neither one builds credit history. A teenager can use a debit card responsibly for years and still have no credit score when they turn 18.

Debit and prepaid cards are useful for teaching spending discipline and money management. They let a teenager practice budgeting, track expenses, and avoid overspending. But they do not accomplish the goal of building credit history before adulthood. If credit building is the priority, an authorized user account or a secured card is necessary.

Some banks offer teen checking accounts with debit cards and educational tools. These accounts are designed to teach financial habits but should not be confused with credit-building products. A teenager might use both—a debit card for daily spending and an authorized user account for credit history—to get the benefits of each.

What parents should watch for when adding a teenager as an authorized user

Adding a teenager as an authorized user is a way to teach spending habits and build credit, but it requires clear expectations. The parent should decide in advance whether the teenager can make purchases freely or whether certain categories (like restaurants or online shopping) are off-limits. Some parents set a dollar limit per transaction or per month. Others require the teenager to ask permission before using the card.

The parent should also explain how credit works: that charges are not information programs, that the bill must be paid in full or interest accrues, and that late payments damage both their credit scores. A teenager who understands these consequences is less likely to treat the card as a gift card.

Parents should monitor the account regularly, either by checking statements online or by reviewing them with the teenager each month. This teaches the teenager to read a credit card statement and gives the parent a chance to catch unauthorized charges or overspending early. It also creates a habit of accountability that the teenager can carry into their own accounts later.

If the parent's financial situation changes—job loss, divorce, medical debt—the parent should consider removing the teenager from the account to protect the teenager's credit score. The authorized user account will remain on the teenager's credit report, but new damage will not accumulate after removal.

Moving from authorized user to an independent card at 18

At 18, a teenager can explore for their own credit card. Issuers will look at the teenager's credit history, which may include years of authorized user accounts. A teenager with a good credit score from being an authorized user on a parent's account is more likely to be approved for a regular card with better terms than someone explore with no credit history.

The teenager should gather documents before explore: a government-issued ID, proof of income (a job offer letter, pay stub, or tax return), and proof of address (a utility bill or lease). Some issuers also ask for a Social Security number. Having these ready speeds up the process.

A teenager's first independent card may have a lower credit limit and higher interest rate than a parent's card, even with good credit history. This is normal. As the teenager builds their own payment history over time, they can request credit limit increases or explore for better cards with rewards or lower rates.

The teenager should understand that they are now solely responsible for the debt. Missed payments, high balances, and late fees are their responsibility, not the parent's. This is the moment when the habits learned as an authorized user become critical.

Frequently Asked Questions

Can a teenager get a credit card without a parent?

No. Federal law requires cardholders to be at least 18 years old. Before 18, the only way to build credit is to become an authorized user on a parent's or guardian's account. At 18, a teenager can explore for their own card if they have income and a valid ID.

Does being an authorized user hurt the parent's credit?

No. Adding an authorized user does not change the parent's credit score. However, if the parent misses payments or carries high balances on the account, both the parent's and the authorized user's credit scores are affected. The account is shared, so both people benefit from good payment history and both are harmed by poor payment history.

What happens to the teenager's credit if the parent removes them as an authorized user?

The account remains on the teenager's credit report and continues to affect their score based on the payment history it built. Removing the teenager stops new charges and new payment history from being added to their credit file, but the past history stays. This is useful if the parent's finances deteriorate and they want to protect the teenager's score from future damage.

Is a secured card worth the deposit for a teenager?

Yes, if the teenager has no other way to build credit. If the teenager is already an authorized user on a parent's account with good payment history, a secured card may not be necessary. If the teenager is starting from zero at 18, a secured card is one of the fastest ways to build credit because it reports to credit bureaus and can be converted to a regular card within a year or two.

Can a teenager build credit with a debit card?

No. Debit cards do not report to credit bureaus, so they do not build credit history no matter how responsibly they are used. Debit cards are useful for teaching spending habits and money management, but they should not be the only tool if the goal is to have a credit score by age 18.
