You must be at least 18 years old to get a credit card in your own name
Credit card companies are required by federal law to verify that you are a legal adult before they issue you a card. That means you need to be 18 or older. There is no exception for minors, even if a parent co-signs or gives permission. If you are under 18, the only way to build credit history is through an authorized user account on someone else's card, or through a secured credit card once you turn 18.
The age requirement exists because credit cards create a legal contract between you and the card issuer. At 18, you can sign binding contracts. Before that, you cannot. This is the same reason you cannot sign a lease, take out a loan, or open a bank account in your own name until you turn 18.
Key Takeaways
- You must be 18 years old to open a credit card account in your own name, with no exceptions for minors.
- Before 18, you can become an authorized user on a parent's or guardian's credit card to start building credit history.
- At 18, you can open a secured credit card (which requires a cash deposit) even if you have no credit history yet.
- Credit card companies verify your age and identity using your Social Security number and other documents before issuing a card.
What happens if you are under 18 and want to build credit
Being an authorized user means your name is added to someone else's credit card account. You get your own card linked to that account, but the account holder is responsible for paying the bill. The payment history shows up on your credit report, which means you start building a credit score even though you do not own the account.
This is the most common way teenagers build credit before turning 18. A parent or guardian adds you to their card, you use it for small purchases (or they use it on your behalf), and the on-time payments help your credit score grow. When you turn 18 and explore for your own card, you will already have a credit history, which makes approval more likely.
The downside is that you have no control over the account. If the account holder misses a payment or carries a high balance, that damage shows up on your credit report too. You are building credit, but you are not building it alone.
Getting your first credit card at 18
When you turn 18, you have two main paths. If you already have a credit history from being an authorized user, you can explore for a regular credit card from most issuers. Your chances of approval are better because you have a track record of on-time payments.
If you have no credit history, you will likely need a secured credit card. This is a real credit card, but it requires you to put down a cash deposit first — usually between $200 and $2,500. The deposit becomes your credit limit. You use the card like any other card, make monthly payments, and the payment history builds your credit score. After six to twelve months of on-time payments, many issuers will convert your account to a regular unsecured card and return your deposit.
Secured cards are not a punishment — they are a tool designed specifically for people with no credit history or poor credit. Banks use the deposit as protection because they have no way to know yet whether you will pay your bills on time.
What credit card companies check before issuing a card
When you explore for a credit card at 18 or older, the issuer verifies your age and identity using your Social Security number. They run a background check through the major credit bureaus (Equifax, Experian, and TransUnion) to see your credit history and score. They also verify your income or employment to make sure you have a way to pay the bill.
The issuer is required by law to confirm you are who you say you are and that you are old enough to sign a contract. This is why you need to provide your full legal name, date of birth, and Social Security number on every process. If the information does not match government records, the process will be denied.
Some issuers also check your bank account history or ask for recent pay stubs. This is not about your age — it is about whether you have income. At 18, you do not need to have a job to get a credit card, but you do need to show some way to repay what you borrow.
Why 18 is the legal threshold
The age of 18 is the legal definition of adulthood in the United States. At 18, you can sign contracts, vote, serve in the military, and take on debt. Credit cards are a form of debt, so the law requires you to be an adult to sign the agreement that comes with them.
Before 18, you are considered a minor, and contracts you sign are not legally binding in most cases. A credit card company cannot force you to pay a bill if you are under 18 because the contract itself would not hold up in court. This is why they will not issue you a card, even if your parents promise to pay the bill.
The difference between being an authorized user and a cardholder
An authorized user is someone added to an existing account. You can use the card, but you do not own the account and you are not legally responsible for the debt. The primary cardholder is responsible for all payments.
A cardholder is the person whose name is on the account and who signed the credit agreement. You are legally responsible for paying the bill, even if someone else uses the card. You own the account, and the payment history is tied to your credit report.
At 18, you can become a cardholder for the first time. Before 18, you can only be an authorized user. This is an important distinction because it affects your legal responsibility and your credit-building power.
What to know before you get your first card at 18
Getting a credit card at 18 is a real financial responsibility. You are borrowing money that you have to pay back, usually with interest. If you do not pay your full balance each month, the card issuer charges you a fee based on your interest rate, which can be 15% to 25% or higher depending on your credit score and the card.
Missing payments damages your credit score, which affects your ability to borrow money for years. Late payments stay on your credit report for seven years. This is why it is important to understand how credit cards work before you explore — not just how to use one, but what happens if you do not pay.
Many people recommend starting with a secured card or a card with a low credit limit so you can learn to manage debt without taking on too much risk. Use the card for small purchases you would make anyway, pay the full balance each month, and watch your credit score grow.
Frequently Asked Questions
Can I get a credit card before I turn 18 if my parent co-signs?
No. Federal law does not allow credit card companies to issue cards to anyone under 18, even with a co-signer or parental permission. A co-signer would make a parent legally responsible for your debt, but it does not change the fact that you are a minor. The only option before 18 is to become an authorized user on an existing account.
Does being an authorized user hurt my credit if the account holder misses a payment?
Yes. Payment history shows up on your credit report whether you own the account or not. If the primary cardholder misses a payment, it damages your credit score too. This is why it matters who adds you to their card — you are trusting them to pay on time.
What if I turn 18 but have no income yet?
You can still get a secured credit card, which requires a cash deposit instead of proof of income. Some issuers also count financial aid, allowance, or part-time work as income. Call the card issuer and ask what they accept. If you cannot get approved for any card, wait a few months and try again — your situation may change.
Will my credit score go down if I open a new credit card at 18?
It may go down slightly in the short term because opening a new account is a hard inquiry on your credit report. But if you use the card responsibly and pay on time, your score will recover and grow over the next few months. The long-term benefit of building credit history outweighs the small temporary dip.
Can I remove myself from my parent's credit card account once I turn 18?
Yes. You can ask the card issuer to remove you as an authorized user at any time. However, once you are removed, that account's payment history stops showing up on your credit report. If you have no other credit history, your credit score may drop. It is usually better to keep the account open and build your own credit card account alongside it.
