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

The federal law that governs credit cards — the Truth in Lending Act — requires you to be a legal adult to sign a credit contract. That means 18 is the minimum age across all 50 states, with no exceptions for emancipated minors or those with parental permission.

If you are under 18, you have two paths forward: become an authorized user on someone else's card, or wait until you turn 18 to open your own account. Each path works differently and has different consequences for your credit history.

Key Takeaways

  • You must be 18 to open a credit card account in your name, and this age requirement applies in every state.
  • Before 18, you can be added as an authorized user on a parent's or guardian's card, which may help build credit history without requiring your own account.
  • When you turn 18, card issuers will often send you offers, but you will need to meet their income and credit requirements to be approved.
  • Becoming an authorized user does not require you to pay the bill, but it does appear on your credit report if the card issuer reports authorized user accounts.
  • Some card issuers require you to be 21 and have independent income to open a card without a co-signer, depending on how they interpret the CARD Act.

Why 18 is the legal minimum

Credit card companies are lending you money. The law treats a credit card agreement as a binding contract, and you cannot sign a binding contract until you are 18. This is the same reason you cannot sign a lease, take out a loan, or enter most other financial agreements before that age.

The Truth in Lending Act does not give issuers any discretion on this point. A 17-year-old cannot open a credit card account, even if they have a job, a co-signer, or excellent credit history. The moment you turn 18, you become legally able to sign the agreement, but that does not mean every issuer will approve you — they still check your income, credit history, and other factors.

Becoming an authorized user before 18

An authorized user is someone who can use a credit card account but is not legally responsible for paying the bill. The primary account holder — usually a parent or guardian — remains responsible for all charges and payments. You can become an authorized user at any age, and many card issuers allow it for children as young as 13.

When you are an authorized user, the card issuer may report your activity to the credit bureaus. This means the account can appear on your credit report and help build your credit history before you turn 18. However, not all issuers report authorized user accounts, so ask before you are added. If the account is reported and the primary holder misses payments or carries high balances, that damage appears on your credit report too.

Being an authorized user does not teach you how to manage your own money or build credit in your own name. When you turn 18 and open your first card, you will start with a blank credit history unless the authorized user account was reported. Even if it was reported, you will likely face stricter terms — lower credit limits, higher interest rates — because you have no independent credit record.

What happens when you turn 18

On your 18th birthday, you become legally able to open a credit card. In practice, card issuers begin sending you offers weeks or months before that date, and you may see pre-approved offers arrive in the mail. These offers are not guarantees — they are invitations to explore, and the issuer will still review your process and may deny it.

To open a card at 18, you will need to provide your Social Security number, proof of income (a job, a student loan, or other regular income), and a valid government ID. If you have no credit history, you may be offered a secured card, which requires a cash deposit that becomes your credit limit. If you have been an authorized user on a reported account with good payment history, you may may have access to for an unsecured card with a small credit limit.

Some card issuers interpret the CARD Act of 2009 to require that you be 21 and have independent income before they will approve you without a co-signer. Others have no such requirement and will approve 18-year-olds with a job. This varies by issuer, so if you are denied, try a different card company or ask whether adding a co-signer would change the decision.

Income requirements and how they are verified

Card issuers must verify that you have income before they approve you. Income means money you receive regularly — wages from a job, student loans, allowance from a parent, disability payments, or other sources. The issuer will ask you to report your annual income on the process, and they may ask for proof.

Proof of income usually means a recent pay stub, a tax return, a letter from your employer, or a bank statement showing regular deposits. If you are 18 and living at home, some issuers will count parental support as income if you can document it. If you have no income at all, you cannot open a credit card in your name — the law requires issuers to verify that you have the ability to pay.

At 18, your income does not have to be high. Many issuers approve first-time cardholders with part-time jobs earning $12,000 to $15,000 per year. The income requirement exists to protect you from taking on debt you cannot pay back, not to exclude young people from credit.

Credit limits and interest rates for young cardholders

If you are approved for your first card at 18, expect a low credit limit — often $300 to $500. This is not a punishment; it is standard practice for anyone with no credit history. The issuer is managing risk by limiting how much you can borrow until you prove you will pay on time.

Your interest rate will likely be higher than what older cardholders with established credit receive. A typical first card for an 18-year-old might carry an APR of 18% to 24%, compared to 12% to 16% for someone with a long history of on-time payments. This difference reflects the fact that young people statistically default more often than older cardholders.

You can improve both your limit and your rate by paying your full balance on time every month for six to twelve months. After that, you can ask for a credit limit increase, and you may may have access to for a card with better terms. Building credit takes time, but it starts the moment you open your first account.

Co-signers and parent-linked accounts

If you are 18 but have no income or a very low income, you may be able to open a card with a co-signer — usually a parent or guardian who agrees to pay the bill if you do not. A co-signer is legally responsible for the debt, so they are taking on real risk. Not all card issuers offer co-signed accounts, and those that do may charge higher interest rates or require a larger deposit.

Some banks offer student credit cards or young adult accounts that are designed for people 18 to 21 with limited credit history. These accounts sometimes allow a parent to monitor spending or set limits, but the card is still in your name and your responsibility. Read the terms carefully to understand what a parent can and cannot do with the account.

A co-signer is different from an authorized user. If you are an authorized user on your parent's card, they are the account holder and you are just using their card. If your parent is a co-signer on your card, you are the account holder and they are backing you up. Only the account holder's name appears on the credit report as the primary borrower.

Frequently Asked Questions

Can I get a credit card at 17 if I have a job and a co-signer?

No. The Truth in Lending Act requires you to be 18 to sign a credit card agreement, and this applies even with a co-signer or a job. You can become an authorized user on someone else's card at any age, but you cannot open your own account until you turn 18.

Will being an authorized user hurt my credit if the primary holder misses payments?

Yes, if the card issuer reports the authorized user account to the credit bureaus. Late payments and high balances on that account will appear on your credit report and lower your credit score. Ask the issuer whether they report authorized user accounts before you are added, and monitor your credit report after you are added to catch any problems early.

What if I turn 18 but have no income yet?

You will not be approved for a credit card without income. If you are in school, you may may have access to for a student loan, which counts as income for credit card purposes. Otherwise, you will need to find a job or other source of regular income before you can open a card. A secured card, which requires a cash deposit, may be easier to get approved for than an unsecured card.

Do I need to wait until I turn 18 to start building credit?

No. If you become an authorized user on a parent's card before 18 and the issuer reports the account, that activity will appear on your credit report and help build your credit history. This gives you a head start when you open your own card at 18, though you will still start with a low limit and higher interest rate.

Can a credit card issuer require me to be 21 to open an account?

Some issuers interpret the CARD Act to require applicants to be 21 and have independent income, but this is not a federal requirement. The law only requires you to be 18. If one issuer denies you, try another, or ask whether adding a co-signer would change the decision.
