The Legal Minimum Age for Credit Cards
You must be at least 18 years old to open a credit card in your own name. This is a federal requirement under the Truth in Lending Act. At 18, you can sign a contract with a card issuer, and they can report your payment history to the credit bureaus — which means you start building a credit record.
Before 18, you cannot hold a credit card account by yourself. Some card issuers allow parents or guardians to add a minor as an authorized user on an existing account, but that is a different arrangement and does not create a separate account in the minor's name.
Key Takeaways
- You must be 18 years old to open a credit card account in your own name, and the card issuer will verify your age before approval.
- Minors can become authorized users on a parent's or guardian's card before turning 18, which may help build credit history if the issuer reports it.
- At 18, you will need to show proof of income or have a co-signer, depending on the card issuer's requirements and your credit history.
- Your first card as an 18-year-old will likely have a lower credit limit and higher interest rate than cards offered to people with established credit.
- Building credit early — even with a secured card or as an authorized user — makes it easier to get better terms on future cards and loans.
What Happens When You Turn 18
Once you reach 18, you become legally able to enter into a credit agreement. Card issuers will ask you to provide your Social Security number, date of birth, and income information. They will verify your age through the information you submit and may check your credit report if you have one.
At 18 with no credit history, most issuers will either decline your process, require a co-signer (usually a parent), or offer you a card with a lower starting credit limit — often $300 to $500. Some issuers have products specifically designed for first-time cardholders or students, which may have less stringent income requirements.
Building Credit Before You Turn 18
If you want to start building credit history before 18, the most common route is becoming an authorized user on a parent's or guardian's account. As an authorized user, you receive a card linked to their account and can make purchases, but the account holder remains responsible for the bill. Your payment history on that account may be reported to the credit bureaus under your name, depending on the card issuer.
Not all issuers report authorized user activity to the credit bureaus, so ask before you are added to an account. If they do report it, on-time payments will help you build a positive credit record. Late payments will also be reported, so this arrangement works best if the account holder pays on time consistently.
Another option is a secured credit card, which some issuers offer to people under 18 with a co-signer. You deposit money into a savings account held by the issuer, and that deposit becomes your credit limit. You use the card like a regular card, and your payments are reported to the credit bureaus. After 12 to 24 months of on-time payments, many issuers will convert the account to a standard card and return your deposit.
Income Requirements at 18
Card issuers are required by federal law to verify that you have a reasonable ability to repay what you charge. At 18, this usually means showing proof of income. Income can come from a job, a stipend from a parent or guardian, investment returns, or other regular sources — the issuer will define what counts.
If you have no income, some issuers will let a parent or guardian co-sign the process. A co-signer is legally responsible for the debt if you do not pay, so the issuer is more willing to approve the card. Other issuers will straightforward decline if you cannot show income, regardless of whether someone is willing to co-sign.
Credit Limits and Interest Rates for Young Cardholders
Your first card at 18 will almost certainly have a lower credit limit than cards offered to people with established credit. A typical starting limit is $300 to $1,000, though some cards for first-time users start lower. The limit is based on your income, credit history (or lack of it), and the issuer's risk assessment.
Interest rates for first-time cardholders are also typically higher. A card for someone with no credit history might carry an APR (annual percentage rate) of 18% to 25%, compared to 12% to 18% for someone with good credit. This is because you have no track record of repaying debt, so the issuer charges more to offset the risk.
Your credit limit and interest rate are not permanent. As you make on-time payments and build credit history, you can request a credit limit increase after six months to a year. Over time, you may also be offered cards with lower interest rates and better terms.
What to Avoid as a Young Cardholder
The most common mistake young cardholders make is carrying a balance and paying interest. Credit cards are meant to be paid in full each month if possible. If you charge $500 and pay only the minimum, you will owe interest on the remaining balance, and that interest compounds monthly. Over time, a small purchase can cost far more than the original price.
Another mistake is opening multiple cards at once to build credit faster. Each process triggers a hard inquiry on your credit report, which temporarily lowers your score. Opening several cards in a short period signals to issuers that you may be taking on more debt than you can handle, which can hurt your chances of approval on future applications.
A third mistake is missing payments. Even one late payment will be reported to the credit bureaus and will lower your credit score. It will also trigger late fees and may cause your interest rate to increase. If you are struggling to pay, contact the card issuer before the due date — many offer hardship programs or payment plans.
Student Cards and Special Programs for Young Adults
Many card issuers offer cards specifically for college students or young adults with limited credit history. These cards often have lower income requirements, smaller starting credit limits, and rewards tailored to student spending (such as cash back on groceries or gas). Some require proof of student status, such as a .edu email address or enrollment verification.
Student cards may also come with educational resources about credit and budgeting. Some issuers waive the annual fee for the first year or offer a lower APR for the first few months. These cards are designed to help you build credit while you are still in school, so the terms are usually more forgiving than standard cards.
Frequently Asked Questions
Can I get a credit card at 17 if I have a co-signer?
No. Federal law requires you to be 18 to sign a credit card contract, and a co-signer does not change that requirement. A co-signer makes themselves responsible for the debt, but they cannot make you legally able to sign the agreement. You will need to wait until you turn 18.
Will being an authorized user hurt my credit if the account holder misses a payment?
Yes. If the primary account holder misses a payment and the issuer reports it to the credit bureaus, that late payment will appear on your credit report as well. This is why it is important to be added to an account only if the account holder has a strong history of on-time payments.
What is the difference between a secured card and a regular card?
A secured card requires you to deposit money upfront, and that deposit becomes your credit limit. A regular card does not require a deposit. Secured cards are easier to get at 18 with no credit history, but they charge interest on purchases just like regular cards. After you build credit, you can move to a regular card.
Do I need to have a job to get a credit card at 18?
Most issuers require proof of income, which usually means a job. However, income can also come from a parent or guardian, student loans, investments, or other regular sources. If you have no income, you may need a co-signer, though not all issuers accept co-signers.
How long does it take to build credit as an authorized user?
Credit bureaus typically begin reporting authorized user activity within one to two billing cycles after you are added to the account. However, building a strong credit score takes time — usually six months to a year of on-time payments before you see a meaningful improvement in your score.
