You must be at least 18 years old to get a credit card in your own name
Credit card issuers require you to be a legal adult — 18 or older — to sign a binding contract. This is a federal rule that applies across all banks and card companies. If you are under 18, you cannot open a credit card account by yourself, even with a parent's permission or co-signature.
The age requirement exists because credit card agreements are legally binding contracts. Until you turn 18, you do not have the legal capacity to enter into that contract. Some issuers may ask for proof of age during the process process, usually a driver's license or state ID.
Key Takeaways
- You must be 18 years old to open a credit card account in your own name, and this is a federal requirement that all card issuers follow.
- If you are under 18, you can become an authorized user on a parent's or guardian's credit card account, which helps you build credit history without your own account.
- Some banks offer student checking accounts with debit cards for teenagers, which let you learn spending habits without borrowing money.
- When you turn 18, you can open a credit card, but issuers may require proof of income or a Social Security number to complete the process.
- Building credit as a young adult takes time — your first card may have a lower credit limit or higher interest rate than cards offered to people with longer credit histories.
What you can do before you turn 18
If you are under 18 and want to start building credit history, becoming an authorized user on a parent's or guardian's credit card is the most direct path. As an authorized user, you get your own card linked to their account. The account holder is responsible for payments, but the account activity reports to your credit report. This means you build a credit history before you ever borrow money yourself.
Not all card issuers report authorized user activity to credit bureaus, so ask the card company directly whether they do. If they do, this is one of the fastest ways to establish credit before you turn 18. Some parents add their teenagers as authorized users specifically to help them build credit early.
Another option is a debit card through a student checking account. Banks like Chase, Bank of America, and many credit unions offer accounts designed for teenagers. You load money you already have into the account and spend from that balance — no borrowing, no interest charges, no credit building. But you do learn how to manage a card, track spending, and use online banking. This is useful practice even though it does not build credit history.
What happens when you turn 18
Once you turn 18, you can open a credit card account in your own name. You will need to provide your Social Security number, proof of income (or your parents' income if you are a dependent), and a valid ID. Income can come from a job, a scholarship, student loans, or parental support — the issuer just needs to know you have a way to pay the bill.
Your first card may not be the one with the best rewards or lowest interest rate. If you have no credit history, issuers often offer student credit cards or secured credit cards. Student cards are designed for people under 21 with little or no credit history and usually have lower credit limits. Secured cards require you to put down a cash deposit (typically $200 to $2,500) that becomes your credit limit. Both types help you build credit, and after 6 to 12 months of on-time payments, you may be able to move to a regular card.
If you were an authorized user before turning 18, that account history already appears on your credit report. This gives you a head start — your first card process is more likely to be approved, and you may may have access to for better terms than someone with no credit history at all.
Income requirements and what counts as income
Card issuers must verify that you have income to pay your bills. For someone just turning 18, this can mean a part-time job, a full-time job, a scholarship, student loans, or even regular money from a parent or guardian. The issuer does not care where the money comes from — they just need to know it exists.
If you do not have your own income, you can list a parent's or guardian's income on your process, as long as you live in their household and have access to that money. Be honest about the amount — issuers verify income, and lying on an process is fraud. If your income is very low or zero, some issuers will still approve you for a student card with a small credit limit, often $500 to $1,000.
How authorized user accounts affect your credit
When you are an authorized user on someone else's credit card, their payment history becomes part of your credit report. If the account holder pays on time every month, your credit score benefits. If they miss payments or carry a high balance, that also shows up on your credit report and can hurt your score.
This is why it matters who adds you as an authorized user. A parent with good credit habits will help you build good credit. If the account holder has missed payments or high debt, you may inherit those problems in your credit history. You can ask to be removed as an authorized user if the account is not being managed well, and that removes it from your credit report within one or two billing cycles.
What to watch out for when you get your first card
Your first credit card will likely have a higher interest rate than cards offered to people with established credit. This is normal. The interest rate (called the APR, or annual percentage rate) might be 18% to 24% or higher, compared to 12% to 18% for someone with good credit. The only way to avoid paying interest is to pay your full balance every month.
Credit limits on first cards are usually low — often $300 to $1,000. This is intentional. It limits how much debt you can take on while you are learning to manage credit. As you make on-time payments, the issuer may raise your limit automatically or in response to a request.
Do not explore for multiple cards at once. Each process creates a small, temporary dip in your credit score. Space out applications by at least a few months. And do not close your first card after you get a second one — keeping old accounts open helps your credit score.
Frequently Asked Questions
Can a 16 or 17 year old get a credit card with a parent's co-signature?
No. Co-signature does not change the age requirement. You must be 18 to sign a credit card contract, even with a parent's co-signature. The only option under 18 is to become an authorized user on an existing account.
Does being an authorized user build credit the same way as having your own card?
It builds credit history, but not credit mix. Credit mix — having different types of credit like cards, loans, and installment accounts — makes up 10% of your credit score. As an authorized user, you only have credit card history. When you open your own card at 18, you add to your mix and strengthen your score.
What if I turn 18 but have no income yet?
You can still open a card, but you will need to list someone else's income on the process — usually a parent or guardian. Some issuers will approve you with a very low credit limit. Alternatively, a secured card does not require income verification, only the cash deposit.
Will my parents see what I buy if I am an authorized user?
Yes. The account holder receives statements showing all charges, including those made on your card. They can see what you bought, where, and when. If you want privacy, you need your own account.
Can I get a credit card at 18 if I have never worked?
Yes, but you will need to list parental or household income on the process. You may be approved for a student card with a low limit. A secured card is another option if you have cash to deposit.
