You must be at least 18 years old to open a credit card in your own name
Credit card issuers — banks, credit unions, and card companies — are required by federal law to verify that you are a legal adult before they issue you a card. That means you need to be 18 or older. There is no exception for minors, even if a parent co-signs or guarantees the debt.
If you are under 18 and want to build credit history, your options are different. You can become an authorized user on a parent's or guardian's card, or you can open a savings account and work toward a secured credit card once you turn 18. Both paths let you start building a credit record before you explore for your own card.
Key Takeaways
- You must be 18 years old to open a credit card account in your own name, and no co-signer can change this requirement.
- Becoming an authorized user on a parent's card before age 18 can help you build credit history without opening your own account.
- Once you turn 18, you can open a secured credit card, which requires a cash deposit and is designed for people with no credit history.
- Card issuers will ask for proof of income or employment when you turn 18, so having a job or other income source makes approval more likely.
- Your credit score at 18 starts at zero, not negative, so your first card is the beginning of your credit record.
Why 18 is the legal minimum
The Credit Card Accountability Responsibility and Disclosure Act (CARD Act) of 2009 set 18 as the minimum age for credit card ownership. The law treats a credit card contract the same way it treats any other legal contract — you must be a legal adult to sign one and be held responsible for the debt.
A parent or guardian cannot sign the contract on your behalf or co-sign to lower the age requirement. The card must be in your name, and you must be 18 to sign it. Some card issuers may ask for additional proof of income or a Social Security number, but age is the first gate.
Becoming an authorized user before 18
An authorized user is someone who can use a credit card account but is not legally responsible for paying the bill. The primary cardholder — usually a parent — remains responsible for all charges and payments. As an authorized user, you get your own card with your name on it, and your activity on that card can be reported to the credit bureaus.
This means that if the primary cardholder pays on time and keeps the balance low, your credit score can start building while you are still under 18. When you turn 18 and open your own card, you will already have a credit history, which can help you get better terms and interest rates.
Not all card issuers report authorized user activity to credit bureaus, so ask the card company before you become an authorized user. Some do it automatically; others require you to request it. The primary cardholder can also remove you from the account at any time, which will stop the credit reporting.
Opening your first card at 18
When you turn 18, you can open a credit card account in your own name. Most card issuers will ask for a few pieces of information: your Social Security number, proof of income (a recent pay stub or tax return), and your date of birth to confirm you are 18.
If you have no credit history — because you were never an authorized user — you may not be approved for a standard credit card right away. In that case, a secured credit card is usually the next step. A secured card requires you to put down a cash deposit, typically between $200 and $2,500. That deposit becomes your credit limit. You use the card like a regular card, and if you pay on time, the issuer reports your activity to credit bureaus. After 6 to 18 months of on-time payments, many issuers will convert your account to an unsecured card and return your deposit.
Some card issuers also offer student credit cards designed for people aged 18 to 21 with limited or no credit history. These cards usually have lower credit limits and higher interest rates than cards for people with established credit, but they are easier to get approved for.
What you need to bring when you explore
When you turn 18 and explore for a credit card, have these documents ready:
- A government-issued photo ID (driver's license, passport, or state ID) to prove your age and identity
- Your Social Security number
- Proof of income, such as a recent pay stub, tax return, or letter from your employer stating your job title and salary
- Your current address
You can explore online, by phone, or in person at a bank or credit union branch. Online applications are usually the fastest — you can complete them in 10 to 15 minutes. The issuer will contact you within a few days to confirm your information or ask follow-up questions.
If you do not have a job, some issuers will count other income sources: financial aid from school, money from a parent or guardian, or income from a side job or freelance work. Be honest about what you earn, because the issuer will verify it and lying on an process can result in denial or account closure later.
Building credit as a young adult
Your credit score at 18 starts at zero, not negative. You have no history yet, so there is nothing to hurt you. Every on-time payment, every low balance, and every year you keep the account open adds to your score. Missing a payment or carrying a high balance will lower it.
The fastest way to build credit is to use your card for small purchases you can pay off in full each month. This shows lenders that you can borrow money and repay it reliably. Avoid carrying a balance just to "build credit" — the interest you pay is not worth the small boost to your score.
After 6 to 12 months of on-time payments, you may receive offers for other cards or higher credit limits. Do not rush to accept them. One card used responsibly is better than multiple cards with high balances. Focus on keeping your first card active and paid on time.
Frequently Asked Questions
Can I get a credit card before I turn 18 if my parent co-signs?
No. Federal law does not allow co-signers to lower the age requirement for credit cards. You must be 18 to open an account in your own name, even with a parent's may provide. Before 18, your only option is to become an authorized user on a parent's existing card.
What happens to my authorized user account when I turn 18?
Your authorized user account stays open and active unless the primary cardholder closes it or removes you. The credit history you built as an authorized user remains on your credit report, which helps your score when you open your own card. You can keep using the authorized user card and have your own card at the same time.
Do I need a job to get a credit card at 18?
Most card issuers prefer that you have income, but it does not have to be from a job. School financial aid, money from a parent, or income from freelance work can count. Be truthful about your income on the process, because issuers verify it and false information can lead to denial or account closure.
What is the difference between a secured card and a regular card?
A secured card requires a cash deposit that becomes your credit limit. A regular card does not. Secured cards are designed for people with no credit history or poor credit. Once you build a good payment history, most issuers will convert your secured card to a regular card and return your deposit.
Will my credit score go down if I open a credit card at 18?
Opening a new card will cause a small, temporary dip in your score because the issuer runs a hard inquiry on your credit report. This dip usually recovers within a few months. The long-term benefit of having an active, paid-on-time account far outweighs this small initial drop.
