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 card issuers — banks, credit unions, and finance companies. You cannot get around this by having a parent co-sign; the law treats 18 as the legal threshold for financial contracts, not a guideline that varies by circumstance.

Before 18, your only option is to become an authorized user on someone else's card — typically a parent's. As an authorized user, you get your own card linked to their account, but they remain legally responsible for all charges. This does not build credit in your name, though some issuers now report authorized user activity to credit bureaus.

At 18, you can walk into a bank or explore online and open a card yourself. Issuers will still check your credit history and income, so being old enough is necessary but not sufficient — you also need to meet their lending standards.

Key Takeaways

  • You must be 18 to sign a credit card agreement; no exceptions exist for younger applicants, even with parental permission.
  • Before 18, you can be added as an authorized user on a parent's card, which gives you a card to use but does not build your own credit history.
  • At 18, issuers will still review your credit score and income before approving you, so age alone does not may provide you will receive a card.
  • The Credit Card Accountability Responsibility and Disclosure Act (CARD Act) of 2009 requires issuers to verify income for applicants under 21, which may slow approval if you have little work history.

Why 18 is the legal floor, not a may provide of approval

Reaching 18 means you can explore, but issuers have their own standards. Most require a credit score, which you may not have if you have never borrowed money. If you have no credit history at all, some issuers will deny you outright; others will offer a secured credit card that requires a cash deposit.

Income verification is another hurdle. The CARD Act requires issuers to confirm that applicants under 21 have a reasonable ability to pay. If you are 18 and just starting work, you may need to show recent pay stubs or a job offer letter. Some issuers will count parental income if you can document it, but this varies by bank.

A few issuers market cards specifically to young adults with no credit history — these often come with higher interest rates and lower credit limits. The tradeoff is that approval is more likely, and building a positive payment history can help you move to better cards later.

Becoming an authorized user before you turn 18

If a parent adds you to their card before you are 18, you can start using credit while still a minor. The parent's credit limit and payment history explore to the account, so if they pay on time, that history may help you when you later open your own card. Some issuers now report authorized user accounts to the credit bureaus in the authorized user's name, which means you build a credit history without legal responsibility.

Being an authorized user has limits. You cannot change the credit limit, request a different card design, or close the account. If the primary account holder misses payments or runs up debt, that damage appears on your credit report too. You also have no legal recourse if the primary holder disputes charges or disputes your use of the card.

The benefit is practical: you learn how credit works, you get a card to use for everyday purchases, and you may start building a credit score before you are old enough to sign your own agreement. When you turn 18, you can explore for your own card with some credit history already in place.

What happens when you turn 18 and have no credit history

If you reach 18 without ever being an authorized user, you are starting from zero. Credit bureaus have no record of you, so you have no credit score. Issuers cannot predict whether you will pay them back based on past behavior.

Your options narrow to cards designed for people with no credit or poor credit. A secured credit card requires you to deposit cash — typically $200 to $2,500 — which becomes your credit limit. You use the card like any other, and after 12 to 24 months of on-time payments, the issuer may convert it to an unsecured card and return your deposit. Secured cards charge annual fees and higher interest rates, but they are one of the few paths open to someone with no credit history.

Some issuers offer student credit cards to people aged 18 to 24 who are enrolled in college. These typically have lower credit limits and higher interest rates, but they do not require a credit history. You will need proof of enrollment and income (from work or financial aid).

Income requirements for applicants under 21

The CARD Act requires issuers to verify that applicants under 21 have income sufficient to pay their bills. This does not mean you need a high income — it means you need to show you have some income and that it is reasonable relative to the credit limit you are requesting.

Income can come from employment, financial aid, investment returns, or support from family members. If you list parental support, you will usually need to provide documentation — a letter from the parent, a bank statement showing transfers, or a tax return. If you work, recent pay stubs or an offer letter will do.

This requirement exists because younger borrowers are statistically more likely to default on credit card debt. Issuers use income verification to reduce their risk. If you cannot document income, you will likely be denied, even if you are 18 or older.

The difference between being 18 and being 21

At 21, the CARD Act's income verification requirement no longer applies. Issuers can still check your credit and income, but they are not legally required to do so. In practice, most still will — income verification is standard underwriting, not just a rule for young people.

The real difference is that by 21, you have had three years to build a credit history. If you opened a card at 18 and paid on time, your credit score has improved, and you now may have access to for better cards with lower interest rates and higher limits. If you did not open a card until 21, you are still starting from scratch.

Some issuers also raise credit limits automatically for customers who reach 21 and have a clean payment history. This is not may provide, but it is common enough that age 21 marks a subtle shift in how issuers treat you.

Frequently Asked Questions

Can I get a credit card at 17 if my parent co-signs?

No. Co-signing does not change the age requirement. Federal law requires you to be 18 to enter a credit card contract, regardless of parental involvement. Your parent can add you as an authorized user instead, which lets you use a card linked to their account.

What if I am 18 but have no income?

You will likely be denied by most issuers, because the CARD Act requires them to verify income for applicants under 21. If you can document parental support or financial aid, some issuers will count that. Otherwise, a secured credit card is your best option — it requires a cash deposit instead of income verification.

Does being an authorized user build my credit score?

It depends on the issuer. Some report authorized user accounts to credit bureaus, which means the account history appears on your credit report. Others do not report it. Ask the card issuer before you are added whether they report authorized user activity to Equifax, Experian, and TransUnion.

Can I remove myself from my parent's card once I turn 18?

You cannot remove yourself unilaterally — only the primary account holder can do that. If you want your own card, you explore separately. Your parent's card remains on your credit report as long as the account is open, which can help or hurt your credit score depending on how well the account is managed.

What is the highest credit limit I can get at 18?

There is no legal maximum, but issuers typically start young cardholders with limits between $300 and $1,000. The limit depends on your credit score, income, and the issuer's policies. Secured cards often match your deposit amount, so a $500 deposit gives you a $500 limit.
