You must be at least 18 years old and have a Social Security number or ITIN to open a credit card account in the United States

Credit card companies are required by federal law to verify your age and identity before issuing a card. You cannot hold a credit card in your own name before age 18, even if a parent co-signs. If you are under 18, your only option is to be added as an authorized user on someone else's account — you get a card linked to their account, but you do not own it and are not legally responsible for the debt.

Once you turn 18, you can open your own account. The card issuer will ask for your Social Security number (or an Individual Taxpayer Identification Number if you do not have a Social Security number). They use this to pull your credit report and verify your identity. Without one of these numbers, you cannot open a credit card account.

Key Takeaways

  • You must be at least 18 years old and have a Social Security number or ITIN to open a credit card in your own name.
  • If you are under 18, you can be added as an authorized user on a parent's or guardian's account, but you will not build your own credit history.
  • Having no credit history does not disqualify you — secured cards and cards designed for first-time users exist specifically for people starting from zero.
  • A credit card company will check your credit report, income, and existing debts before deciding whether to issue a card.
  • Being denied once does not lock you out permanently; you can reapply after addressing the reason you were denied.

What happens if you have no credit history yet

A blank credit report does not mean you cannot get a card. Many card issuers offer products specifically for people with no credit history or a very short one. These cards typically have a lower credit limit (often $300 to $500) and a higher interest rate than cards offered to people with established credit, but they work the same way and report to the credit bureaus, so using one responsibly builds your credit score over time.

The most common option for someone with no history is a secured credit card. You deposit cash into a savings account held by the card issuer — usually $200 to $2,500 — and that amount becomes your credit limit. You use the card like any other card, pay your bill each month, and after 6 to 18 months of on-time payments, the issuer typically converts it to a regular unsecured card and returns your deposit. During that time, your payment history is reported to the credit bureaus and begins building your score.

Some issuers also offer unsecured cards for people with limited or no credit history. These cards do not require a deposit, but they come with higher fees and interest rates. The trade-off is that you do not have to tie up cash upfront.

What card issuers check before saying yes or no

When you submit an application, the card issuer looks at three main things: your credit report, your income, and your existing debts. Your credit report shows whether you have paid past bills on time, how much debt you currently owe, and how long you have had credit accounts open. If you have no report yet, that is not automatically a rejection — it just means the issuer has less information to work with.

The issuer will also ask for your annual income. They use this to set a credit limit and to check whether you have the income to support the debt. There is no minimum income requirement set by law, but individual issuers set their own thresholds. Some will issue cards to people with very low income; others will not.

If you already have credit accounts open — a car loan, student loans, or other credit cards — the issuer will look at how much you owe and whether you are paying on time. High existing debt or late payments make approval less likely, because the issuer is assessing the risk that you will not pay this card either.

When a card issuer will deny you

A card issuer can turn down your application for several reasons. The most common are: no credit history and no income to offset that risk; a credit score below the issuer's minimum (this varies by card, from around 550 to 700); late payments or defaults on past accounts; or income too low relative to the credit limit you are requesting. Being denied does not mean you can never get a card — it means that particular issuer decided the risk was too high at that moment.

If you are denied, the issuer is required by law to tell you why, either in the denial letter or by phone if you ask. Read that reason carefully. If it is "no credit history," a secured card is your next step. If it is "credit score too low," you can work on paying down existing debt and making on-time payments for several months, then reapply. If it is "income too low," you may need to reapply when your income increases, or look for a card issuer with lower income thresholds.

How being an authorized user affects your options

If you are under 18, you can ask a parent or guardian to add you as an authorized user on their credit card account. You will receive a card with your name on it, and you can use it to make purchases. However, you are not the account holder — the parent or guardian is legally responsible for all charges, and the account appears on their credit report, not yours.

Being an authorized user does build some credit history in your name, depending on the card issuer and the credit bureau. Some issuers report authorized user accounts to all three credit bureaus (Equifax, Experian, and TransUnion); others report to only one or two; some do not report at all. This means the benefit to your credit score varies. When you turn 18 and want to open your own card, you may have a small credit history, or you may still be treated as someone with no history — it depends on which accounts were reported.

The advantage of being an authorized user is that you can start learning how credit cards work before you are legally responsible for one. The disadvantage is that you are not building a credit history you can control, and if the primary account holder misses payments or runs up high balances, that damage appears on your credit report too.

Age requirements for specific card types

All credit cards require you to be 18 or older to hold them in your own name. This applies to student cards, business cards, travel cards, and every other type. The only exception is the authorized user status described above.

Some card issuers market cards specifically to college students or people in their first years of work. These cards often have lower credit limits and higher interest rates, but they are designed to be easier to get approved for if you have limited income or credit history. The age requirement is still 18, but the income requirement may be lower or the issuer may count student loans or financial aid as income.

What to do if you are denied

Request the reason for the denial in writing. The issuer must provide this within 30 days of your application. Once you know why you were denied, you have a few options. If the reason is no credit history, apply for a secured card or a card designed for first-time users. If the reason is a low credit score, focus on paying down existing debt and making all payments on time for at least three to six months, then reapply to the same issuer or try a different one with lower credit score requirements.

If the reason is insufficient income, you can reapply once your income increases, or you can look for issuers that have lower income thresholds or that count other income sources (such as financial aid, disability payments, or spousal income). Do not apply to multiple issuers in a short period — each application creates a hard inquiry on your credit report, and too many inquiries in a short time can lower your score and make future denials more likely.

Frequently Asked Questions

Can I get a credit card if I am 17?

No, you must be 18 to open a credit card account in your own name. Before age 18, you can be added as an authorized user on a parent's or guardian's account, which gives you a card to use but does not make you the account holder.

Do I need a job to get a credit card?

You do not need a traditional job, but you do need to report some form of income. This can include employment income, self-employment income, investment income, disability payments, student loans, or spousal income. Different issuers accept different income sources, so if one declines you, another may not.

What is the difference between a secured card and a regular card?

A secured card requires you to deposit cash upfront, which becomes your credit limit. A regular card does not require a deposit. Secured cards are easier to get approved for if you have no credit history, but they come with the trade-off of tying up your own money. After six to eighteen months of on-time payments, most secured cards convert to regular cards and return your deposit.

Will being denied for a credit card hurt my credit score?

The application itself creates a hard inquiry on your credit report, which can lower your score slightly. However, the denial itself does not appear on your credit report. Multiple applications in a short time will have a larger impact on your score, so space out applications by at least a few months.

Can I reapply to the same card issuer after being denied?

Yes, but wait at least three to six months and address the reason you were denied first. If you were denied for a low credit score, spend that time paying down debt and making on-time payments. If you were denied for low income, reapply once your income has increased. Reapplying immediately after a denial is unlikely to result in approval.
