You cannot open a credit card in your own name at 17 in the United States
Federal law requires you to be 18 years old to sign a binding contract, and a credit card agreement is a contract. Issuers like Chase, Capital One, and American Express will not approve an application from someone under 18, regardless of income or credit history. This applies even if you have a job, pay taxes, or have excellent grades.
There are three actual paths forward: becoming an authorized user on someone else's card, getting a secured card once you turn 18, or waiting until your 18th birthday to apply. Which one makes sense depends on why you want a card now and what you want to build.
Key Takeaways
- You must be 18 to hold a credit card in your own name; federal law treats it as a binding contract you cannot legally sign at 17.
- Becoming an authorized user on a parent's or guardian's card can help you build credit history before you turn 18, though you are not legally responsible for the bill.
- Secured cards designed for first-time cardholders become available the day you turn 18 and require a cash deposit but report to credit bureaus like regular cards.
- Your credit score at 18 depends partly on what you do now: authorized user accounts can help, but only if the primary cardholder pays on time.
Becoming an Authorized User Before 18
An authorized user is someone who can use a credit card but is not the person responsible for paying the bill. A parent, guardian, or other adult can add you to their existing card without you being 18. You get a physical card with your name on it, you can make purchases, and the account appears on your credit report.
The catch: you have no legal obligation to pay, and the primary cardholder's payment history is what matters. If your parent pays the bill on time every month, that positive history builds your credit score. If they miss payments or carry high balances, your score gets damaged too. You are essentially borrowing their credit reputation.
This works best if the primary cardholder has good habits and is willing to keep the account open after you turn 18. Some issuers let you convert to your own card at 18 without closing the account; others require you to apply separately. Ask the card issuer before you get added.
What Happens When You Turn 18
The day you turn 18, you can apply for a credit card in your own name. Most issuers will not approve you immediately if you have no credit history — they have no record of you paying bills or managing debt. This is where a secured card becomes useful.
A secured card requires you to deposit cash into a savings account held by the issuer. That deposit becomes your credit limit. You use the card like any other card, the issuer reports your payments to the three credit bureaus (Equifax, Experian, and TransUnion), and after 6 to 18 months of on-time payments, many issuers convert it to a regular unsecured card and return your deposit. Capital One, Discover, and Bank of America all offer secured cards to people with no credit history.
If you were an authorized user before 18, that history helps. Issuers see that you have been using credit responsibly (assuming the primary cardholder paid on time), and you may be approved for a regular card without needing a deposit. This is why starting as an authorized user at 17 can matter.
Building Credit Before You Are 18
Credit bureaus track authorized user accounts the same way they track primary accounts. If you are added to a card with a long history and low balances, your credit score can jump 20 to 50 points within a month or two. This head start matters when you apply for your own card at 18.
The account stays on your report even after you turn 18, as long as the primary cardholder keeps it open. If they close it, the account stops helping your score, though it remains visible for seven years. This is why you want to stay on a card with a good payment history, not one that is about to be closed.
If the primary cardholder has poor credit or high balances, being added to their card can hurt you. Ask to see their credit report or at least ask directly: do they pay on time, and what is their balance relative to the credit limit? If the answer is no or high, it is better to wait until 18 and start with a secured card on your own terms.
Other Ways to Build Credit at 17
A credit card is not the only way to build a credit history. Some credit unions offer credit-builder loans to people under 18 with a parent's co-signature. You borrow a small amount (usually $500 to $1,000), the money goes into a savings account you cannot touch, and you make monthly payments. Once you pay it off, you have a loan history on your credit report and the money is yours.
Becoming an authorized user on a utility bill or phone plan does not build credit — those accounts do not report to credit bureaus. Only credit accounts (cards, loans, lines of credit) show up on your report. If you have a job, ask your employer whether they report to credit bureaus; some do, though most do not.
What to Avoid at 17
Do not apply for a credit card in your own name before 18. The application will be denied, and multiple denials in a short time can lower your score slightly (though you do not have a score yet if you have never had credit). More importantly, it wastes time and can make you look unprepared when you do apply at 18.
Do not ask someone to co-sign a credit card for you. Co-signers are responsible for the debt if you do not pay, and most issuers do not allow co-signers on credit cards anyway. If an adult is willing to help you build credit, being an authorized user is the safer route for both of you.
Do not assume that being added to someone's card means you can spend without limits. The primary cardholder can remove you at any time, and if you run up charges they do not approve, it damages your relationship and your credit history. Treat it like your own money.
Frequently Asked Questions
Can I get a credit card if I turn 18 next month?
You can apply the day you turn 18. Some issuers approve applications within hours; others take a few business days. If you want a card ready to use on your birthday, apply a few days before and have your ID ready to verify your age when you turn 18.
Does being an authorized user hurt my credit if the primary cardholder stops paying?
Yes. Late payments on the account show up on your credit report just as they do on the primary cardholder's. If you are concerned about their payment habits, ask them directly or check their credit report before agreeing to be added. You can ask to be removed at any time.
What if my parents do not have a credit card I can be added to?
You can wait until 18 and open a secured card. You will need a Social Security number, a checking account, and a cash deposit (usually $200 to $2,500). The deposit becomes your credit limit, and after six months of on-time payments, many issuers will convert it to a regular card.
Will my authorized user account stay on my credit report after I turn 18?
Yes, as long as the primary cardholder keeps the account open. If they close it, the account stops helping your score but remains visible on your report for seven years. This is why staying on a good account matters even after you have your own card.
Can I use a debit card instead of a credit card to build credit?
No. Debit cards do not report to credit bureaus because you are spending your own money, not borrowing. Only credit accounts (credit cards, loans, lines of credit) build a credit history. A debit card is useful for managing money, but it does not help your credit score.
