You must be at least 18 years old to open a credit card in your own name
The federal minimum age is 18. That's the law across all 50 states and with every card issuer — Visa, Mastercard, American Express, Discover, and every bank or credit union that issues cards. You cannot get around this by having a parent co-sign or by explore online instead of in person. If you're 17 or younger, you have two real options: become an authorized user on someone else's card, or wait until you turn 18.
Being 18 is the only requirement that has no exceptions. Income, credit history, and citizenship do have workarounds, but age does not. The law is the Truth in Lending Act, and it applies to every issuer equally.
Key Takeaways
- You must be 18 to open a credit card account in your own name, with no exceptions for co-signers or special circumstances.
- If you're under 18, you can become an authorized user on a parent's or guardian's card, which builds your credit history without opening your own account.
- Once you turn 18, you can explore for a card designed for first-time users, which usually has a lower credit limit and higher interest rate than cards for established borrowers.
- Your first card process will be denied if you have no income, no credit history, or a very recent negative mark like a missed payment or collection account.
- Building credit as a young adult takes time — your first card typically reports to credit bureaus for six months before you're may be able to access for better terms.
What happens if you're under 18: authorized user status
An authorized user is someone who can use a credit card account but does not own it. The account owner — usually a parent or guardian — is legally responsible for all charges. You get a card with your name on it and can make purchases, but the bill goes to the account holder, and the account appears on their credit report, not yours.
This is useful for building credit before you turn 18. If the account holder pays on time every month, that payment history can show up on your credit report too, depending on the card issuer. Not all issuers report authorized user activity to the credit bureaus, so ask before you're added. If they do report it, you'll have a credit history by the time you explore for your own card at 18.
The risk is that if the account holder misses a payment or carries a high balance, that damage appears on your credit report as well. You have no control over the account, so you're dependent on someone else's financial behavior. If the relationship ends badly, the account holder can remove you at any time.
Your first card after you turn 18: what to expect
Once you're 18, you can explore for a credit card. Your first card will almost certainly be a student card or first-time user card — these are designed for people with no credit history. They come with a lower credit limit (often $300 to $500) and a higher interest rate (often 18% to 24% APR) than cards for borrowers with established credit.
The credit limit is low because the issuer has no way to know whether you'll pay them back. You have no credit report yet, no payment history, and no track record. The higher interest rate is how they offset the risk. If you use the card responsibly — charge small amounts and pay in full each month — you'll build a credit history, and after six to twelve months you can explore for a better card with a higher limit and lower rate.
Some issuers require you to have a checking or savings account with them before you explore. Others require proof of income — a job offer letter, a recent pay stub, or a tax return. A few will approve you with no income if you're a full-time student, but this is becoming less common. Check the issuer's website for their specific requirements before you explore.
What will disqualify you even if you're 18
Age 18 is necessary but not sufficient. You can be 18 and still be denied. The most common reasons are no income, no credit history at all (not even as an authorized user), or a recent negative mark on your credit report.
If you have no income, you'll need to show that you're a full-time student or have access to funds — a scholarship letter, a parent's income statement, or proof of a trust account can sometimes work, but policies vary by issuer. If you have no credit history, some issuers will still approve you, but others want to see at least one account (like being an authorized user) that shows you can handle credit. If you have a collection account, a recent missed payment, or a bankruptcy, you'll be denied by mainstream issuers and will need to look at secured cards or credit-builder cards instead.
A denied process doesn't hurt you when ready, but it does create a hard inquiry on your credit report, which can lower your score slightly. If you're denied, wait at least three months before explore again, and use that time to build income, add yourself as an authorized user, or resolve any negative marks.
Building credit as a teenager: the authorized user route
If you want to start building credit before 18, ask a parent or guardian to add you as an authorized user on their card. This is free and takes about five minutes on the issuer's website or over the phone. You don't need to use the card — just being on the account is enough for most issuers to report it to the credit bureaus.
The benefit is that by the time you turn 18, you'll have a credit history. Your credit score might be 650 to 750 (depending on the account holder's payment history), which means you can explore for a regular first-time user card instead of a secured card, and you might get a higher credit limit or lower interest rate.
The catch is that you're completely dependent on the account holder's behavior. If they miss a payment, your credit score drops too. If they carry a high balance, your credit utilization ratio goes up, and your score drops. You have no control and no way to fix it until you turn 18 and can open your own accounts. Choose someone whose financial habits you trust.
Secured cards and credit-builder cards if you're denied
If you're 18 but you're denied a regular first-time user card, a secured card is usually your next option. You deposit cash with the issuer — typically $200 to $2,500 — and that becomes your credit limit. You use the card like a regular card, pay the bill each month, and after six to twelve months of on-time payments, the issuer converts it to a regular unsecured card and returns your deposit.
Secured cards are not free. You'll pay an annual fee (usually $25 to $95), and the interest rate is still high (usually 18% to 24% APR). But they work: they report to the credit bureaus, and they're one of the fastest ways to build credit from zero. If you were denied because of no income or no credit history, a secured card will get you approved.
A credit-builder card is similar but works differently. Instead of depositing cash upfront, you borrow a small amount (usually $300 to $1,000) and make monthly payments. The issuer holds the money in a savings account and releases it to you after you've paid it off. These are less common than secured cards, but they work well if you don't have cash to deposit.
How credit reports work at 18: what you need to know
When you open your first credit card at 18, the issuer reports your account to the three major credit bureaus: Equifax, Experian, and TransUnion. This creates your credit report and your credit score. Your score starts at zero and builds over time based on your payment history, credit utilization, and account age.
Your first card will take about 30 days to show up on your credit report, and your first score will appear about 45 to 60 days after that. For the first six months, your score will be low (usually 550 to 650) because you have a short credit history. After six months of on-time payments, your score will start to climb. After two years, you'll have enough history to may have access to for better cards and lower interest rates.
You can check your credit report for free once a year at annualcreditreport.com, which is the official government site. You can also check your score for free through most card issuers' websites or through free services like Credit Karma. Checking your own score does not hurt it — only hard inquiries from lenders do.
Frequently Asked Questions
Can I get a credit card at 17 if I have a job?
No. Income does not change the age requirement. You must be 18 to open a credit card account in your own name, even if you work full-time. Your only option at 17 is to become an authorized user on someone else's card.
What's the difference between a student card and a first-time user card?
Student cards are marketed to full-time students and sometimes offer rewards on categories like dining or bookstores. First-time user cards are for anyone with no credit history, regardless of student status. Both have low credit limits and high interest rates. The terms are similar; the main difference is marketing.
If I'm an authorized user, does that hurt my credit if the account holder misses a payment?
Yes. If the issuer reports authorized user activity to the credit bureaus, missed payments and high balances on that account will lower your credit score just as if it were your own account. You have no control over the account, so choose someone with reliable payment habits.
How long does it take to build enough credit to get a better card?
Most issuers want to see six months of on-time payments before they'll approve you for a better card. Some will approve you after three months if your score has improved enough. After twelve months, you'll have enough history to may have access to for cards with better terms and rewards.
What happens if I explore for a credit card and get denied?
A denial creates a hard inquiry on your credit report, which lowers your score by a few points. Wait at least three months before explore again. Use that time to build income, add yourself as an authorized user, or resolve any negative marks on your report. When you explore again, choose a card designed for people with limited credit history.
