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

Credit card issuers require you to be a legal adult — 18 or older — to sign a contract and be held responsible for debt. This is a federal requirement, not a choice individual card companies make. If you are under 18, you cannot open an account by yourself, but you have other options to build credit history before you reach that age.

The age requirement exists because credit card agreements are legally binding contracts. When you sign the application, you are promising to repay what you borrow. The law does not allow minors to enter binding contracts, so banks cannot issue cards to anyone under 18, even if a parent co-signs.

Key Takeaways

  • You must be 18 years old to open a credit card account in your own name, regardless of your income or credit history.
  • If you are under 18, you can become an authorized user on a parent's or guardian's card, which may help you build credit history.
  • Some banks offer student credit cards starting at age 18, though they often require proof of income or a co-signer.
  • Turning 18 does not automatically give you access to credit — you will still need to meet the issuer's income and creditworthiness requirements.

Becoming an Authorized User Before Age 18

If you are under 18, you can ask a parent or guardian to add you as an authorized user on their existing credit card account. As an authorized user, you receive your own card linked to their account and can make purchases, but the account holder remains responsible for all payments and debt.

Being an authorized user can help you build credit history because the account activity reports to the credit bureaus under your name. If the primary account holder pays on time and keeps the balance low, this positive history appears on your credit report. This gives you a head start when you turn 18 and open your own card.

The account holder can remove you at any time, and you have no legal obligation to pay the balance. This is why it works well for younger people — you get the credit-building benefit without the legal responsibility.

What Happens When You Turn 18

Reaching 18 makes you legally able to open a credit card, but it does not may provide approval. Card issuers will still check your credit report, income, and other financial information before deciding whether to issue you a card.

If you have been an authorized user on a parent's account since you were younger, you will have a credit history already. This makes approval more likely and may may have access to you for better terms. If you have no credit history at all, issuers may require you to provide proof of income, offer you a card with a lower credit limit, or ask you to find a co-signer.

Some issuers have student credit cards designed specifically for people aged 18 to 21 who are in school. These cards often have lower credit limits and may require less income documentation, but they still require you to be 18.

Income and Employment Requirements at 18

Even at 18, you will need to show the card issuer that you have income or a way to repay what you borrow. This can come from a job, a scholarship, student loans, or money from a parent or guardian — the issuer just needs to see that funds exist to cover the debt.

You will need to provide your Social Security number and answer questions about your annual income on the application. The issuer will verify this information and may contact your employer. If you have no income, some issuers will let a parent or guardian co-sign, making them responsible for the debt if you do not pay.

The amount of income you need varies by issuer and card type. Student cards often have lower income thresholds than premium cards, and some issuers are more flexible with 18-year-olds than others.

Using a Co-Signer if You Have No Credit History

If you are 18 but have no credit history and limited income, a co-signer can help you open a card. A co-signer is usually a parent or guardian who agrees to be legally responsible for the debt if you do not pay. Their credit history and income are considered alongside yours during the approval process.

Having a co-signer does not mean they control the account — you make the purchases and payments. But if you miss payments, the issuer can pursue the co-signer for the full balance. This is why co-signers are usually family members who trust you to manage the account responsibly.

Once you have built your own credit history over time, you may be able to remove the co-signer from the account, though this depends on the issuer's policies.

Secured Cards as an Alternative at 18

If you are 18 and cannot get approval for a standard credit card, a secured credit card may be an option. Secured cards require you to deposit money into a savings account held by the bank — usually between $200 and $2,500. That deposit becomes your credit limit, and you use the card like a regular card.

Secured cards report to the credit bureaus just like regular cards, so on-time payments build your credit history. After 6 to 18 months of responsible use, many issuers will convert your secured card to a regular unsecured card and return your deposit.

Secured cards have higher fees and interest rates than standard cards, so they are best used as a stepping stone to build credit quickly, not as a long-term solution.

State Laws and Special Circumstances

Federal law sets the minimum age at 18, and no state can lower this requirement. However, some states have additional rules about minors and financial accounts. For example, some states allow minors to open savings accounts or have limited financial powers at 16 or 17, but credit cards are not included in these exceptions.

If you are 18 but still in high school or living with parents, you can still open a credit card — age is the only legal barrier. Your living situation or school status does not affect your right to apply.

Emancipated minors — young people who have been legally declared independent by a court — can sometimes open accounts before 18, but this is rare and varies by state. If you believe you may may have access to, contact your state's court system or a legal aid organization for guidance.

Frequently Asked Questions

Can I get a credit card at 17 if my parents co-sign?

No. Federal law requires you to be 18 to sign a credit card contract, and co-signing does not change this. A parent can add you as an authorized user on their card, but you cannot open your own account until you turn 18.

Will my credit history as an authorized user transfer to my own card?

Yes. The account activity you built as an authorized user stays on your credit report after you turn 18 and open your own card. This history helps you get approval and may may have access to you for better terms.

What if I turn 18 but have no job?

You can still apply, but you will need to show some source of income — a part-time job, student loans, a scholarship, or money from family. If you have none, a co-signer with income can help you get approved.

Do I need a Social Security number to open a credit card at 18?

Yes. Card issuers require a Social Security number to pull your credit report and verify your identity. If you do not have one, you will need to apply for one before you can open a credit card account.

Can I remove a co-signer from my credit card later?

It depends on the issuer. Some allow you to remove a co-signer after a certain period of on-time payments, while others do not. Check your card's terms or contact the issuer to ask about their co-signer removal policy.
