You must be at least 18 years old to hold a credit card in your own name
Federal law sets 18 as the minimum age to sign a credit card agreement. This applies across all states and all card issuers — there is no exception for minors, regardless of income or credit history. If you are under 18, you cannot be the primary cardholder on an account.
The age requirement exists because a credit card agreement is a legal contract. Until you turn 18, you do not have the legal capacity to enter into binding contracts in most situations. Card issuers need someone who can be held responsible if the account goes unpaid.
Some people under 18 can still access credit through other routes — as an authorized user on a parent's card, or through a secured card once they turn 18 — but these are different from holding your own account.
Key Takeaways
- You must be 18 years old to be the primary cardholder on a credit card account.
- Authorized users on a parent's card can be any age, but the parent remains legally responsible for all charges.
- Some card issuers offer secured cards designed for people building credit, available at 18 with a cash deposit.
- Being added as an authorized user does not build your own credit history — only accounts in your name do that.
- Age alone is not enough to get a card at 18; you will also need income or a co-signer, depending on the issuer's requirements.
What happens if you are under 18 but want to build credit
The most common option is becoming an authorized user on a parent's or guardian's credit card. An authorized user can use the card to make purchases, but the primary cardholder — the adult — is legally responsible for paying the bill. The account appears on the primary cardholder's credit report, not yours.
Some card issuers report authorized user accounts to credit bureaus, which means activity on that card may show up on your credit report. This can help you build a credit history before you turn 18. However, this depends entirely on the issuer's policy — not all of them report authorized user accounts. Ask the card issuer directly whether they report to the three major credit bureaus (Equifax, Experian, and TransUnion) for authorized users.
The risk of being an authorized user is that you have no control over the account. If the primary cardholder misses payments or runs up debt, that damage appears on your credit report too. You also cannot remove yourself from the account — only the primary cardholder can do that.
Getting your own card at 18 with no credit history
At 18, you can apply for a card in your own name, but most issuers will ask for proof of income. This can be a job, a student loan, or in some cases a scholarship or grant. If you have no income, some issuers will accept a co-signer — usually a parent — who agrees to pay the bill if you do not.
If you have no income and no one willing to co-sign, a secured credit card is often the only option. You deposit cash with the card issuer — typically $200 to $2,500 — and that amount becomes your credit limit. You use the card like a regular card, make monthly payments, and the issuer reports your activity to credit bureaus. After 6 to 18 months of on-time payments, many issuers will convert the account to a regular unsecured card and return your deposit.
Secured cards charge annual fees (usually $25 to $95) and often have higher interest rates than standard cards. But they are designed specifically for people with no credit history or poor credit, and they do build your credit report from the ground up.
Why card issuers ask for income at 18
The Credit Card Accountability Responsibility and Disclosure Act (CARD Act) requires issuers to verify that cardholders have a "reasonable ability to pay." For someone 18 or older with no credit history, this usually means documented income. The issuer wants evidence that you can cover at least the minimum monthly payment.
Income can come from employment, but it does not have to. Student loans, grants, and regular support from family members can count, depending on the issuer. Some issuers are stricter than others — a large bank may require a job, while a credit union might accept a student loan or parental support.
If you are denied for a card because of insufficient income, you have the right to request the specific reason in writing. The issuer must provide this within 30 days of your request. Understanding why you were denied helps you know whether to try a different issuer, wait until your income changes, or pursue a secured card instead.
State laws do not override the federal age requirement
Some states have their own consumer protection laws around credit, but none of them lower the age requirement below 18. A few states have laws that make it easier for minors to work or earn income, which indirectly affects credit access, but the credit card age floor remains 18 nationwide.
If you live in a state with a higher age of majority (a few states use 19 or 21 for some legal purposes), that does not affect credit cards. Federal banking law sets 18 as the threshold, and that is what card issuers follow.
What to know about student credit cards
Many card issuers market cards specifically to college students, often with lower income requirements or the option to list a parent's income on your application. These cards typically have lower credit limits and higher interest rates than standard cards, but they are easier to get at 18 with limited income.
Student cards usually require proof that you are enrolled in a degree program at an accredited school. Some issuers ask for this at application; others verify it later. The card itself does not look different, but the issuer uses student status as a substitute for income verification.
Student cards often come with rewards or benefits aimed at college life — cash back on dining or books, for example — but read the terms carefully. The interest rate and annual fee matter far more than a small rewards rate if you carry a balance.
Frequently Asked Questions
Can I get a credit card at 17 if I turn 18 soon?
No. You must be 18 at the time you apply. Some issuers may allow you to apply a few weeks before your birthday and have the card arrive after you turn 18, but you cannot be approved while you are still 17. Check with the issuer about their specific policy if your birthday is very close.
Does being an authorized user on my parent's card build my credit?
Only if the card issuer reports authorized user activity to the credit bureaus. Not all issuers do this. Ask your parent to contact the card issuer and confirm whether authorized users appear on credit reports. If they do not, being an authorized user will not help you build credit history.
What if I have a job but no Social Security number yet?
You will need a Social Security number to open a credit card account. If you are a U.S. citizen or permanent resident and have a job, you can apply for a Social Security number at your local Social Security office. The process usually takes a few weeks. Until you have one, you cannot apply for a card.
Can I use a prepaid card instead of a credit card to build credit?
No. Prepaid cards do not build credit history because they are not credit products — you load money onto them first, then spend it. Credit bureaus do not track prepaid card activity. To build credit, you need an actual credit card or other credit product that reports to the bureaus.
What happens to my authorized user account when I turn 18?
Nothing automatic happens. You remain an authorized user on your parent's card unless one of you requests to remove you. At 18, you can apply for your own card separately. Some people keep the authorized user account for the credit history it provides while also opening their own card to build independent credit.
