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

Federal law sets 18 as the minimum age to enter into a credit card contract. This applies across all states and all card issuers — Visa, Mastercard, American Express, Discover, and every bank or credit union that issues cards. You cannot get around this age requirement by having a parent co-sign or by applying online instead of in person.

If you are under 18, you have two real options: become an authorized user on someone else's account, or wait until you turn 18. Being an authorized user means the card belongs to the primary account holder (usually a parent), but you receive your own card linked to that account and can make purchases. You build a credit history this way, though the account owner is responsible for all payments.

Some banks will issue a debit card to minors with no age minimum, but a debit card is not a credit card — it draws from money you already have rather than borrowing. A debit card does not build credit history the way a credit card does.

Key Takeaways

  • You must be 18 years old to open a credit card account in your own name; no exceptions exist for high income or good credit history.
  • If you are under 18, you can become an authorized user on a parent's or guardian's card and receive your own card to use.
  • Being an authorized user builds your credit history, but the primary account holder remains legally responsible for all charges and payments.
  • Debit cards have no age requirement but do not build credit history the way credit cards do.
  • Once you turn 18, you can open your own card immediately; most issuers do not require you to have an existing credit history.

What happens when you turn 18

The day you turn 18, you become legally able to sign a credit card contract. You do not need to wait for your birthday to pass or for any official verification — you can walk into a bank or apply online as soon as you reach that age. Most card issuers will not ask for proof of age beyond what you provide on the application form.

If you have been an authorized user on someone else's account, that history may appear on your credit report and help you when you open your first card in your own name. However, many issuers will still issue a card to an 18-year-old with no credit history at all. Student credit cards and cards designed for people building credit typically have lower credit score requirements than premium cards.

How being an authorized user works before 18

When you are added as an authorized user, the primary account holder's bank sends you a card with your name on it. You can use it to make purchases, but the bill goes to the primary account holder. They decide the spending limit, receive the statement, and make the payments. You have no legal obligation to pay anything.

The account appears on your credit report in most cases, which means on-time payments help your credit score and missed payments hurt it — even though you are not the one making the payments. This is why parents sometimes add teenagers as authorized users: it builds credit history before the teenager is old enough to open their own account.

Being an authorized user ends when the primary account holder removes you, when you turn 18 and choose to close the card, or when the account itself is closed. The account history may remain on your credit report for several years after it closes, which can help or hurt depending on whether payments were made on time.

Age requirements for different card types

The 18-year-old minimum applies to every type of credit card: student cards, secured cards, rewards cards, business cards, and premium travel cards. No card issuer can legally offer a credit card to someone under 18, regardless of income, employment status, or creditworthiness.

Business credit cards also require the applicant to be 18, even if the business itself is younger or is owned by someone under 18. A minor cannot open a business credit card in their own name.

Some financial institutions offer youth savings accounts or teen checking accounts with no age minimum, but these are not credit products — they do not involve borrowing money or building a credit history.

Building credit as a teenager

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 credit card. Choose an account where payments are made on time consistently, because late payments will damage your credit score just as much as they help it when payments are on time.

You can also ask about becoming an authorized user on a secured credit card, which requires a cash deposit but often has lower approval requirements. The deposit protects the card issuer if you miss payments, and after a year or two of on-time payments, many issuers will convert the card to a regular unsecured card and return your deposit.

Once you turn 18, you can open your own card. Many banks offer student credit cards with no annual fee and lower credit limits, designed specifically for people just starting to build credit. These cards typically have higher interest rates than premium cards, but the interest rate only matters if you carry a balance — if you pay the full statement balance each month, you pay no interest at all.

What to know about credit limits and age

Federal law also limits how much credit card companies can offer to people under 21. If you open your first card between 18 and 21, the card issuer must base your credit limit on your own income, not your parents' income. This usually means a lower starting limit than someone older might receive.

Once you turn 21, card issuers can consider your parents' income if you list them as a reference, which may allow for a higher credit limit. However, listing a parent's income does not make them responsible for your debt — you remain the only person legally obligated to pay.

Frequently Asked Questions

Can I get a credit card at 17 if I have a job?

No. Federal law requires you to be 18 regardless of income or employment. Having a job does not change the age requirement. Your best option is to become an authorized user on a parent's card and wait until you turn 18 to open your own account.

What if I am 18 but have no credit history?

You can still open a credit card. Student cards and secured cards are designed for people with no credit history. A secured card requires a cash deposit but is easier to get approved for. After six to twelve months of on-time payments, you may be able to upgrade to a regular card.

Does being an authorized user hurt my credit if the account owner misses payments?

Yes. Late payments on an account where you are an authorized user appear on your credit report and lower your credit score, even though you are not responsible for paying. This is why it matters which account you ask to join — choose one with a strong payment history.

Can my parent remove me as an authorized user?

Yes. The primary account holder can remove an authorized user at any time without notice. The account will remain on your credit report for several years after removal, so the payment history continues to affect your score.

What is the difference between a credit card and a debit card for age requirements?

Debit cards have no age minimum because they use money you already have. Credit cards require you to be 18 because they involve borrowing money and signing a legal contract. Only credit cards build a credit history.
