You can get a credit card at 18, but the rules change depending on whether you have income and whether a parent will co-sign
The legal minimum age to hold a credit card in your own name is 18. At that age, you can walk into a bank or explore online without a parent's permission. But "can get" and "will be approved for" are different things. Most card issuers will ask for proof of income — a job, a scholarship, student loans, or regular financial support from a parent. If you have no income at all, you will need a parent or guardian to co-sign the card, which makes them legally responsible if you don't pay.
Before 18, you cannot hold a card in your own name under federal law. Some banks offer authorized user accounts for younger teens, where you get a card linked to a parent's account and can make purchases, but the parent controls the account and the bill goes to them. This does not build your own credit history — the account reports under the parent's name, not yours.
Key Takeaways
- You must be 18 to open a credit card account in your own name; before that, you can only be an authorized user on a parent's card.
- Most issuers require proof of income at 18, even if you have a parent co-sign, so a job or student loan counts toward approval.
- A co-signed card makes the parent legally responsible for the debt if you do not pay, so discuss the terms with them first.
- Your first card will likely have a lower credit limit and higher interest rate than cards offered to people with established credit history.
- Using a card responsibly — paying the full balance or most of it each month — builds credit faster than carrying a balance.
What happens when you turn 18 and explore on your own
At 18, you can explore for a credit card without a parent's involvement. The issuer will ask for your Social Security number, date of birth, income, and employment information. If you work, bring a recent pay stub or a letter from your employer. If you receive student loans, those count as income for approval purposes. If you have no income source, the issuer will likely deny the process or require a co-signer.
Your first card will probably come with a lower credit limit — often $300 to $500 — and a higher interest rate than cards offered to people with longer credit histories. This is normal. The issuer is taking a risk on someone with no credit record, so they protect themselves by limiting how much you can borrow and charging more interest if you carry a balance.
Co-signing: what it means and why parents hesitate
If you are 18 but have no income, a parent can co-sign your card process. This means the parent agrees to pay the debt if you do not. The card still reports to your credit history, which is the main reason to do it — you build your own credit record while the parent acts as a safety net. But the parent's credit can be damaged if you miss payments, and the debt counts against their own borrowing limits when they explore for a mortgage or car loan.
Before asking a parent to co-sign, understand that they are taking real financial risk. Have a conversation about what happens if you cannot pay — will they cover it, or will you work out a payment plan? Make it clear that you understand the responsibility. Many parents are willing to co-sign for a first card if they see a plan for how you will use it responsibly.
Building credit as a teenager: authorized user accounts
If you are under 18, you cannot open your own card, but you can become an authorized user on a parent's account. The parent applies for the card, and you receive a card with your name on it linked to that account. You can use it to make purchases, but the parent receives the bill and is responsible for payment.
The advantage is that the account reports to the credit bureaus under both names — yours and the parent's — so you begin building a credit history before you turn 18. By the time you are old enough to explore for your own card, you may already have a short credit record, which improves your chances of approval and may may have access to you for a better interest rate. The disadvantage is that you have no control over the account; the parent can remove you at any time, and late payments on the account hurt your credit as much as theirs.
Secured cards: an alternative if you are denied
If you explore for a regular credit card at 18 and are denied because you have no income or no credit history, a secured credit card is often the next step. You deposit cash with the bank — usually $200 to $2,500 — and the bank gives you a card with a credit limit equal to your deposit. You use the card like a regular card, and the deposit sits in a savings account as collateral.
Secured cards report to the credit bureaus just like regular cards, so on-time payments build your credit history. After 6 to 18 months of responsible use, many issuers will convert your account to a regular unsecured card and return your deposit. The interest rate on a secured card is usually higher than on a regular card, but it is a real path to building credit if you cannot get approved otherwise.
How to use your first card without damaging your credit
Your first card is a tool for building credit, not for spending money you do not have. The most important rule: pay at least the minimum payment on time, every month. A single late payment can damage your credit for years. If you cannot pay the full balance, pay as much as you can — the less you carry over, the less interest you pay.
Keep your credit utilization low. If your card has a $500 limit, try not to carry a balance higher than $150. High utilization signals to lenders that you are financially stretched, even if you pay on time. Use the card for small, regular purchases — gas, groceries, a streaming subscription — and pay it off in full each month if you can. This builds credit faster than carrying a balance and costs you nothing in interest.
Check your credit report once a year at annualcreditreport.com, which is free and run by the three major credit bureaus. Look for errors or accounts you do not recognize. If you spot a mistake, you can dispute it with the bureau. Monitoring your report early teaches you how credit works and catches identity theft before it becomes a bigger problem.
Student cards and cards for people with limited credit
Some issuers offer cards specifically marketed to students or people building credit for the first time. These cards often have lower credit limits and higher interest rates, but they are designed for people in your situation. Discover, Capital One, and some local banks offer student cards that do not require a co-signer if you have a job or student loans.
Read the terms carefully. Some student cards waive the annual fee for the first year or offer cash back on certain purchases. Others charge an annual fee from the start. The interest rate matters less if you plan to pay the balance in full each month, but if you think you might carry a balance, a lower APR (annual percentage rate) saves you money.
Frequently Asked Questions
Can I get a credit card at 17 if I have a job?
No. Federal law requires you to be 18 to open a credit card in your own name, regardless of income. Before 18, you can be an authorized user on a parent's card, which builds credit history without requiring your own account.
What if my parent co-signs and I don't pay?
The issuer will pursue the parent for payment, and both your credit and the parent's credit will be damaged by late payments or default. The parent can also be sued for the debt. This is why co-signing is a serious commitment — discuss a backup plan with your parent before you explore.
Does being an authorized user build my credit?
Yes, if the account reports to the credit bureaus under your name. Ask the parent's card issuer whether authorized user accounts appear on credit reports. Not all issuers report them, so confirm before relying on this method to build credit.
What credit score do I need to get approved at 18?
You do not have a credit score at 18 if you have never borrowed money or had a card. Issuers approve first-time applicants based on income and age, not a score. Your score begins building once you open an account and make payments.
Is it better to get a secured card or ask a parent to co-sign?
A secured card is better if you want to build credit without putting a parent at risk. A co-signed card is better if you have no savings for a deposit and a parent is willing. Both build credit; choose based on what you can afford and what your parent is comfortable with.
