Credit cards for minors under 18 do not exist as standalone products. Federal law requires applicants to be at least 18 to sign a binding credit contract, so a minor cannot open an account in their own name. What a minor can do is join a parent or guardian as an authorized user, which gives them a card with their name on it and a real shot at building credit history before they turn 18.
This guide walks through how authorized user setups work, which issuers accept the youngest teens, and what teen-focused alternatives exist for families that want to teach money habits. The right setup depends on your child's age, your goals, and how much control you want to keep.
Why Credit Cards for Minors Under 18 Do Not Exist on Their Own
Contract law is the main reason. Most states do not let people under 18 sign enforceable contracts for loans or credit. Even if a bank approved a minor, the bank could not force repayment in court if the minor defaulted.
The Credit CARD Act of 2009 added another layer. It requires applicants aged 18 to 21 to either prove independent income or have a cosigner. For applicants under 18, there is no approval path at all. For a full look at the age rules, see our guide on can you build credit before 18.
So when you see ads for teen credit cards, read carefully. Most are either authorized user products, teen debit cards, or prepaid cards marketed with similar language.
The Difference Between Credit, Debit, and Prepaid
Credit cards let you borrow from the issuer and pay back later, often with interest. Only adults can open one in their name.
Debit cards pull from a checking account you already own. Teens can hold debit cards as joint accounts with a parent as young as 13.
Prepaid cards work like debit cards but are loaded with a set amount. No bank account is required. Neither debit nor prepaid cards build credit, since they do not report to the credit bureaus.
How Authorized User Status Works for Minors
Adding an authorized user is the one legitimate way to put a credit card in a minor's hands. The parent or guardian opens the account, and the bank sends a second card with the minor's name on it.
The minor can use the card like any other credit card. At the same time, the account history typically appears on the minor's credit report. That means months or years of on-time payments can build a credit file before the minor turns 18.
Minimum Age by Issuer
Each bank sets its own minimum age for authorized users. Here are common thresholds:
- American Express: no minimum age
- Capital One: no set minimum on most cards
- Chase: 16 or older for most consumer cards
- Discover: 15 or older
- Citi: 13 or older
- Wells Fargo: no set minimum
Always verify the current policy before adding a child. Banks adjust these rules periodically.
Does the Account History Actually Transfer?
Most major issuers report authorized user activity to all three credit bureaus. That means a teen added to a parent's long-standing account may start with a thin credit file that already shows a long history, low utilization, and on-time payments.
But a few issuers report only to certain bureaus or only under specific conditions. Call the bank or check the disclosure before relying on credit building as a motivation.
Also remember that late payments on the primary account may appear on the authorized user's file too. Choose the account carefully.
The Best Setup for Teaching Money Habits
Adding a minor as an authorized user works best when paired with clear ground rules. Set expectations before the card arrives. Our build credit as a teenager guide has a full checklist for families setting this up for the first time.
Common rules that parents use include:
- Spending limits per purchase or per month
- A short list of approved categories like gas, groceries, or lunch
- A requirement to show receipts or transactions weekly
- A rule that the teen reimburses the parent monthly
Apps like Monarch Money help families track spending across multiple cards without handing over bank passwords. Brigit is another budgeting tool that shows real-time balance projections, which helps teens avoid surprises.
If the teen has a part-time job, reimbursing charges each month builds the habit of paying a full balance. That is the single most important credit card habit to learn early.
Alternatives to Credit Cards for Minors Under 18
Authorized user status is not the only route. Families with different goals may want a debit card, a prepaid card, or a credit builder tool. If you want card-specific picks, our roundup of the best credit cards for teens compares the top options.
Teen Debit Cards
Most major banks offer joint teen accounts with debit cards for ages 13 and up. These accounts come with parental controls, spending alerts, and often a savings feature. They do not build credit, but they teach the mechanics of card payments.
Prepaid Cards
Prepaid cards do not require a checking account. You load money on the card, the teen spends it, and you reload as needed. They are useful for younger teens or families without bank accounts. Fees and low limits are the main drawbacks.
Credit Builder Products at 18
The day a teen turns 18, new options open up. The Self.Inc Credit Builder Account lets an 18 year old pay into a locked savings account that reports to the bureaus. When the term ends, the money returns minus fees.
Self Visa Credit Card becomes available once the credit builder account has saved enough to cover the card deposit. That combined product is a powerful way to start a credit file from zero.
Kikoff Credit Account is another option with smaller monthly payments. The Kikoff Secured Credit Card adds a secured card option with a low annual cost.
OpenSky Secured Visa does not require a credit check at all, which makes it a good first credit card for 18 year olds who want immediate access to a real Visa card.
Risks to Watch For
Authorized user setups can backfire if the primary account has problems. Late payments on the parent's card may show up on the teen's credit report.
Before adding a minor, pull your own credit report and check that the account is current. If you are carrying high balances or have missed payments, delay the authorized user setup until you fix those issues.
Credit monitoring through Dovly or free credit monitoring with Creditship helps track what shows up on the teen's file once they are added. Catching errors early is easier than disputing old items later. Credit Saint is a good option if inaccurate items do appear and need to be challenged.
Removing an Authorized User
You can remove an authorized user any time by calling the issuer. Some parents do this right before the teen turns 18 so the teen starts with clean credit under their own habits.
Removing an authorized user may erase that account's history from the teen's credit report at most issuers. If the history was positive, that can drop the teen's score. Weigh the trade-off before removing.
What to Expect After Turning 18
When the authorized user turns 18, they can apply for a card in their own name. The earlier the authorized user setup, the thicker the credit file when they apply. Our step-by-step guide on how to get a credit card at 18 covers the application timeline.
A typical path looks like this:
- Age 13 to 15: added as authorized user on a parent's account
- Age 16: opens a teen checking account with a debit card
- Age 18: opens a secured card or credit builder account
- Age 19 or 20: applies for a student credit card
- Age 21: qualifies for standard adult cards
This sequence builds a FICO score quickly by stacking on-time payment history across multiple accounts.
Saving for the First Card Deposit
Eighteen year olds often need a few hundred dollars for a secured card deposit. Saving through simple challenges like the 100 envelope challenge can fund that deposit in a few months. A high-yield savings account keeps the money accessible and earning interest until the birthday arrives.
Personal loans from MoneyLion or EzLoan are not typically available to 18 year olds with no credit, so saving ahead is the realistic path.
Frequently Asked Questions
Can a 16 year old have a credit card?
A 16 year old cannot have a credit card in their own name but can be added to a parent's card as an authorized user. Chase, Capital One, American Express, and many other issuers allow authorized users at 16 or younger. Some issuers have no minimum age for authorized users.
Does adding my teen as an authorized user affect my credit?
Adding an authorized user typically does not change your credit score. The account stays in your name, and you remain fully responsible for all charges. If your teen overspends, your balance goes up and may raise your utilization, which can indirectly affect your score.
Can minors build credit before turning 18?
Yes. Authorized user status is the main way minors build credit before 18. If the parent's account is reported to the credit bureaus with a strong history, the minor's credit file may show that account once they turn 18 and can access their credit report.
What happens to an authorized user account when the child turns 18?
Nothing automatic. The teen stays on the account until removed. Many parents leave the authorized user status in place while the teen opens their first card on their own, then remove the authorized user card after a year or two. Removing the card may reduce the teen's credit history length.
