A 17-year-old cannot open a credit card in their own name in the United States
Credit card issuers require you to be at least 18 years old to sign a contract. At 17, you lack the legal capacity to enter into a binding agreement, which is what a credit card account is. No major issuer — Visa, Mastercard, American Express, Discover — will issue a card to someone under 18, regardless of income or credit history.
This is a federal requirement under the Truth in Lending Act and the Credit Card Accountability Responsibility and Disclosure Act (CARD Act). The law treats credit agreements the same way it treats other contracts: a minor cannot be held to the terms.
Key Takeaways
- You must be 18 years old to open a credit card account in your own name; no exceptions exist for high earners or employed teenagers.
- Being added as an authorized user on a parent's or guardian's card is the only way to use a credit card before you turn 18.
- Authorized user accounts do not build your own credit history — the account history belongs to the primary cardholder.
- At 18, you can open a card in your own name, but issuers may require proof of income or a co-signer depending on your credit history and employment status.
Becoming an authorized user on a parent's card
If you need to use a credit card before turning 18, ask a parent or guardian to add you as an authorized user on their existing account. The primary cardholder remains responsible for all charges and payments. You receive a card with your name on it and can make purchases, but you have no legal obligation to pay the bill.
The parent or guardian can set limits on what you can spend, and they see every transaction on their statement. Some issuers allow the primary cardholder to set a spending cap through their online account or mobile app. This arrangement lets you learn how credit cards work — how charges post, how statements arrive, what interest means — without the legal responsibility.
Ask the card issuer whether they report authorized user activity to the credit bureaus. Some do, some do not. If they do report it, the account history will appear on your credit report, but it belongs to the primary cardholder. When you turn 18 and open your own card, you start with a blank credit history unless the issuer has been reporting your authorized user activity.
What happens when you turn 18
On your 18th birthday, you can open a credit card account in your own name. You are now legally an adult and can sign a contract. However, issuers do not automatically approve every 18-year-old. They will ask for proof of income — a pay stub, tax return, or letter from an employer — or they may require a co-signer.
If you have no credit history, issuers may offer you a secured card, which requires a cash deposit (usually $200 to $2,500) that serves as your credit limit. You use the card like a regular card, and after 6 to 18 months of on-time payments, the issuer may convert it to an unsecured card and return your deposit.
If you have been an authorized user on a parent's card and the issuer reported that activity to the credit bureaus, you may have a thin credit file. This can help you get approved for a regular card, though interest rates may be higher than they would be for someone with a longer credit history.
Why issuers require you to be 18
Credit card companies cannot legally enforce a contract with a minor. If you were 17 and opened an account, you could theoretically dispute every charge and refuse to pay once you turned 18, and the issuer would have no legal recourse. The law protects minors from being bound to contracts they did not fully understand or that were signed under pressure.
The CARD Act of 2009 added another layer: it prohibits issuers from marketing credit cards to people under 21 on college campuses or through direct mail to college addresses. The law also requires issuers to verify that applicants 21 and older have the income to pay their bills, though this rule does not apply to 18- to 20-year-olds.
Building credit as a teenager
If you want to start building credit before you turn 18, being an authorized user is your main option. Make sure the primary cardholder pays the bill on time every month. Payment history is the largest factor in credit scores, and late payments will hurt both your credit and theirs.
Some issuers offer teen checking accounts with debit cards, which do not build credit but teach you how to manage money. A debit card draws from your own bank account and does not create debt. This is a good way to practice budgeting and learn how transactions work without the complexity of interest or credit reporting.
At 18, if you have been an authorized user for a year or more and the account has a clean payment history, you will have a head start when you open your own card. Your credit score may be high enough to get approved for a regular card without a deposit or co-signer.
Co-signers and alternatives at 18
If you turn 18 with no income and no credit history, you can ask a parent or guardian to co-sign a credit card application. A co-signer is legally responsible for the debt if you do not pay. This is different from being an authorized user — the co-signer's credit is on the line, and the account appears on both your credit reports.
Some issuers do not accept co-signers for credit cards, though they may for other products like loans. If you cannot find a co-signer or prefer not to ask, a secured card is the standard path. You put down a deposit, use the card responsibly for several months, and graduate to an unsecured card.
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 sign a credit card contract, even if you earn $100,000 a year. Being an authorized user on a parent's card is your only option until you turn 18.
Will being an authorized user hurt my parent's credit?
No, not if you and the primary cardholder use the card responsibly. On-time payments help both of you. Late payments or high balances will hurt the primary cardholder's credit score, and may appear on your credit report if the issuer reports authorized user activity.
What if my parent adds me as an authorized user and then removes me?
The account will fall off your credit report within 30 to 60 days. If you had built credit through that account, removing you stops the positive history from helping your score, but it does not erase what already happened. Any late payments that occurred while you were an authorized user will remain on your report.
Can I use a debit card to build credit?
No. Debit cards draw from your bank account and do not create debt, so credit bureaus do not track them. They do not build credit history. A debit card is useful for learning to manage money, but to build credit you need a credit card or loan that is reported to the bureaus.
Do I need a Social Security number to be an authorized user?
Most issuers require a Social Security number for authorized users, though some may accept an Individual Taxpayer Identification Number (ITIN). Ask the card issuer before the primary cardholder requests to add you.
