The Legal Minimum Age for a Credit Card
You must be at least 18 years old to open a credit card in your own name. This is a federal requirement — no card issuer can bypass it. If you are under 18, you cannot be the primary cardholder on any credit card account.
The 18-year minimum exists because credit card agreements are legally binding contracts. Until you reach the age of majority, you do not have the legal capacity to sign a binding contract on your own. Once you turn 18, you can sign the cardholder agreement yourself and become responsible for the debt you create.
Some issuers may require you to be older than 18 — often 21 — but 18 is the legal floor. A few cards have no stated age cap, though most do not advertise an upper limit either.
Key Takeaways
- You must be 18 years old to open a credit card as the primary cardholder, and this is a federal requirement that no issuer can waive.
- If you are under 18, you can become an authorized user on a parent's or guardian's card, which does not require you to sign a contract.
- Some issuers require you to be 21 or older, so check the issuer's specific requirements before you start the process.
- Building credit history early — even as an authorized user — can help you get better rates and terms when you open your own card at 18.
Getting a Credit Card Before You Turn 18
If you are under 18, you cannot hold a credit card in your own name. However, you can become an authorized user on someone else's card — usually a parent's or guardian's. As an authorized user, you get your own card linked to their account, but they remain the legal account holder and are responsible for all charges.
Being an authorized user does not require you to sign anything. The primary cardholder adds you to their account, and the card issuer sends you a card. You can use it to make purchases, and the charges go to the primary cardholder's bill. Many card issuers report authorized user activity to the credit bureaus, which means your credit history can start building even before you turn 18.
This is one of the fastest ways to start building credit as a teenager. Your payment history, credit utilization, and account age all get reported under your name. Just make sure the primary cardholder pays the bill on time — late payments will hurt your credit score too.
What Happens When You Turn 18
Once you turn 18, you can open a credit card in your own name. You will need to provide your Social Security number, proof of income or employment, and a valid government-issued ID. Most issuers also ask for your date of birth to confirm you meet the age requirement.
If you have been an authorized user on a parent's card, that history stays on your credit report. This can work in your favor — issuers see that you have a track record of responsible use, even though you were not the one making payments. Your credit score may already be established, which can help you get approved for a card with better terms.
If you have no credit history at all, you may be offered a secured credit card instead of a standard card. A secured card requires a cash deposit (usually $200 to $2,500) that serves as your credit limit. You use it like a regular card, and after six to twelve months of on-time payments, many issuers will convert it to an unsecured card and return your deposit.
Age Requirements Beyond 18
While 18 is the legal minimum, some card issuers set their own higher age limits. A few major issuers require you to be 21 before you can open a card. This is their own policy, not a legal requirement — they choose to be more restrictive than the law allows.
If you are 18 to 20 and an issuer declines you because of age, try a different card. Many issuers have no age restriction beyond 18, and secured cards almost always accept 18-year-olds. You are not locked out of credit — you just need to find an issuer whose requirements match your age.
Income and Employment Requirements at 18
Being 18 is necessary but not sufficient. You also need to show that you have income. This can be from a job, a scholarship, student loans, or regular financial support from a parent. The issuer wants to know that you have money coming in and can pay your bill.
If you are a full-time student with no job, you may still be approved if you list financial support from a parent as your income. Be honest about the amount — issuers verify income, and lying on the process can result in denial or account closure later. If you have no income at all, you will likely be declined, even if you are 18.
Some issuers are stricter about income verification than others. If one declines you, another may approve you. Secured cards tend to be more lenient on income requirements because the deposit reduces their risk.
Building Credit as a Young Cardholder
Once you have a card, your credit behavior matters when ready. Every payment you make — or miss — gets reported to the credit bureaus. Late payments, high balances, and missed due dates all damage your credit score, which affects your ability to borrow money in the future.
Start with a low credit limit and keep your balance well below that limit. Aim to use no more than 10 to 30 percent of your available credit. Pay your full balance on time every month, or at least pay more than the minimum. This builds a strong credit history that will help you get better rates on future cards, car loans, and mortgages.
If you are an authorized user on a parent's card, you have the same responsibility to use it wisely. The primary cardholder is legally responsible for the debt, but your credit report is affected by how the account is managed. Treat it like your own card.
What to Do If You Are Denied
If you are 18 or older and an issuer declines you, ask why. They are required to tell you the reason — usually insufficient credit history, low income, or their own age policy. This information helps you decide your next step.
If the reason is no credit history, a secured card is your best option. If the reason is age, try a different issuer. If the reason is income, you may need to wait until your income increases or find a co-signer (though few issuers allow co-signers on credit cards anymore).
You can also ask a parent to add you as an authorized user on their card if you are not already. This builds your credit history without requiring you to open your own account, and you can transition to your own card once you have established a credit record.
Frequently Asked Questions
Can a 17-year-old get a credit card?
No, you must be 18 to be the primary cardholder. However, you can become an authorized user on a parent's card at any age. This lets you build credit before you turn 18 and makes it easier to open your own card once you are legally able to.
Do I need a job to get a credit card at 18?
You need to show income, but it does not have to be from employment. Student loans, scholarships, allowances, or financial support from a parent all count as income. Be honest about the amount — issuers verify it, and overstating your income can get your process denied.
What is a secured credit card and how does it work?
A secured card requires you to deposit cash (usually $200 to $2,500) that becomes your credit limit. You use it like a regular card, and the issuer reports your payment history to the credit bureaus. After six to twelve months of on-time payments, many issuers convert it to a regular card and return your deposit.
Will being an authorized user hurt my credit?
No, being an authorized user can help your credit if the primary cardholder pays on time. Your credit report includes the account's payment history, credit limit, and balance, all of which build your credit score. Late payments on the account will hurt your score, but on-time payments help it.
Can I get a credit card if I am 18 but have no credit history?
Yes, but you may be offered a secured card instead of a standard card. A secured card is easier to get approved for because your deposit reduces the issuer's risk. After you build a credit history with it, you can move to a regular card with better terms.
