You must be at least 18 years old to get a credit card in your own name

Federal law sets 18 as the minimum age to enter a binding contract, which includes a credit card agreement. You cannot hold a credit card account as the primary cardholder before then, even if a parent or guardian co-signs. Some card issuers set their own minimum age higher — occasionally 21 — but 18 is the legal floor across all U.S. states.

If you are under 18, you have two real options: become an authorized user on someone else's card, or wait until you turn 18 and open your own account. Being an authorized user means the primary cardholder is legally responsible for all charges, but the card activity may be reported to credit bureaus under your name, which can help build your credit history.

Key Takeaways

  • You must be 18 years old to be the primary cardholder on a credit card account.
  • Before 18, you can become an authorized user on a parent's or guardian's card, and this activity may appear on your credit report.
  • Some issuers require you to be 21 or older, so age requirements vary by card and by bank.
  • Having income or a job is not required by law to get a credit card at 18, though many issuers prefer it.

What happens when you turn 18

At 18, you can walk into a bank branch or apply online for a credit card without parental permission. The card issuer will check your credit report — if you have no history, they will see a blank file. Many issuers will still approve you, especially if you have a bank account with them or a steady income, but the credit limit will usually be low, often $300 to $500.

If you have been an authorized user on a parent's card for a year or more, that history may already be on your credit report, which can improve your chances of approval and your starting credit limit. Not all card issuers report authorized user activity, so ask before relying on it.

Income and employment requirements

Federal law does not require you to have a job or income to get a credit card at 18. However, most issuers do ask about income on the application — they want to know you can pay the bill. If you have no income, some issuers will decline you. Others will approve you with a very low limit.

If you are a student with no job, you can still apply. List any income you receive: allowance, work-study, part-time work, or money from family. Some issuers have student credit card products that are designed for people with limited income. These cards often come with lower limits and higher interest rates, but they exist specifically for this situation.

Building credit as a young adult

Your first credit card is a tool to build credit history, not to borrow money you do not have. Credit bureaus track how you use credit — whether you pay on time, how much of your limit you use, and how long you keep accounts open. This history becomes your credit score, which affects your ability to rent an apartment, get a car loan, or may have access to for better credit cards later.

The fastest way to build credit is to use your card for small purchases you would make anyway, then pay the full balance before the due date each month. This shows lenders you can handle credit responsibly. Carrying a balance and paying interest does not build credit faster — it just costs you money.

Authorized users under 18

If you are under 18 and want to start building credit, ask a parent or guardian to add you as an authorized user on their card. You will receive your own card with your name on it, but the primary cardholder is responsible for all charges. The account activity will appear on your credit report under your name, which means on-time payments help your credit score.

This arrangement works best when the primary cardholder has good payment habits and a low balance. If they miss payments or carry high balances, that negative history will also appear on your credit report. Before becoming an authorized user, understand that you are building credit based on someone else's behavior.

What to watch out for

Do not apply for multiple cards in a short time. Each application triggers a hard inquiry on your credit report, and too many inquiries in a few weeks can lower your score. Space applications out by at least a few months.

Do not assume a high credit limit means you should use it. A common mistake is to max out a new card early on. This raises your credit utilization ratio — the percentage of your limit you are using — and damages your score. Keep your balance below 30 percent of your limit, even if you pay it off monthly.

Do not ignore the card once you get it. Set up a payment reminder so you never miss a due date. One late payment can stay on your credit report for seven years and will significantly lower your score.

Frequently Asked Questions

Can I get a credit card at 17 if I turn 18 soon?

No. You must be 18 on the day you apply. Some issuers may let you apply a few weeks before your birthday and activate the card on your 18th birthday, but you cannot hold an active account before then. Contact the issuer directly to ask about their specific policy.

Does being an authorized user build my credit score?

It can, but only if the issuer reports authorized user activity to the credit bureaus. Not all do. Ask the cardholder's bank whether they report authorized users before you rely on this to build your credit. Even if they do, your score depends on the primary cardholder's payment behavior.

What if I have no credit history at all?

You can still get a credit card at 18. Many issuers approve first-time applicants, though your limit will be low and your interest rate higher. A secured credit card — one backed by a cash deposit — is another option if you are declined for a regular card. You deposit money, receive a card with that amount as your limit, and build credit by using it responsibly.

Do I need a Social Security number to get a credit card?

Yes. Card issuers use your Social Security number to check your credit report and verify your identity. If you do not have one, you cannot open a credit card account in the United States.
