The Short Answer: Not Alone, But With an Adult Co-Signer
A minor cannot open a credit card account by themselves. Credit card companies require the account holder to be at least 18 years old and have a Social Security number. If you are under 18, you have three real paths: become an authorized user on a parent's or guardian's card, open a secured credit card once you turn 18, or wait until you reach the age requirement.
The most common route for teenagers is becoming an authorized user. This means a parent or guardian opens the account in their name, and the card issuer adds you to that account. You get your own card with your name on it, but the adult is legally responsible for all charges. The account appears on your credit report, which means your payment history — good or bad — starts building now.
Key Takeaways
- Minors cannot hold a credit card account in their own name; you must be 18 and have a Social Security number to be the primary account holder.
- Becoming an authorized user on a parent's or guardian's account is the fastest way to start building credit before age 18.
- As an authorized user, you build credit history based on how the primary account holder pays the bill, even if you do not make the payments yourself.
- Once you turn 18, you can open your own secured credit card, which requires a cash deposit but does not require a co-signer.
- Some card issuers allow you to convert from authorized user to primary account holder on your 18th birthday without reapplying.
Becoming an Authorized User: How It Works
When a parent or guardian adds you as an authorized user, the card issuer sends you a card in your name linked to their account. You can use it to make purchases, but the primary account holder receives the bill and is responsible for paying it. The account shows up on your credit report when ready, which means every payment — on time or late — affects your credit score.
This is the most straightforward way to build credit as a minor. You learn how to use a card responsibly while the adult manages the account. Many card issuers report authorized user accounts to the three major credit bureaus (Equifax, Experian, and TransUnion), so your credit history grows even though you are not the one paying the bill.
Not all card issuers report authorized user accounts to credit bureaus, so ask before the account is opened. Discover, Chase, American Express, and Capital One all report authorized user activity, but smaller issuers or store cards may not. If building credit is your goal, confirm the card issuer reports to all three bureaus.
What Happens When You Turn 18
On your 18th birthday, you become a legal adult and can hold a credit card account in your own name. Some card issuers allow you to convert your authorized user account to a primary account without reapplying — you straightforward contact them and request the change. This is the easiest path because your credit history transfers with you, and you keep the same account number and card.
If the card issuer does not offer conversion, or if you want a different card, you can open your own account once you turn 18. Your credit report already shows the payment history from being an authorized user, which gives you a head start. A card issuer reviewing your process will see that you have managed credit responsibly (or not), which affects whether they approve you and what interest rate they offer.
If you do not have an authorized user account by age 18, you will likely need to open a secured credit card. This card requires you to deposit cash into a savings account held by the card issuer — usually $200 to $2,500 — which becomes your credit limit. You use the card like a regular card, pay the bill each month, and after 6 to 18 months of on-time payments, the issuer converts it to a regular unsecured card and returns your deposit.
The Risks of Being an Authorized User
Being an authorized user builds your credit, but it also exposes you to the primary account holder's mistakes. If the account goes unpaid, the late payment appears on your credit report too. If the account is closed with a balance owed, that negative mark follows you. You have no control over the account, so you cannot fix these problems yourself.
Some authorized users also face the temptation to overspend. Because you are not receiving the bill, it is straightforward to lose track of how much you have charged. Set a spending limit with the primary account holder before you start using the card, and check the balance regularly online or through the card issuer's app.
If the primary account holder's credit is poor or they have a history of missed payments, being added as an authorized user will not help your credit. In fact, it may hurt it if they continue to miss payments after you are added. Only become an authorized user on an account managed by someone with a solid payment history.
Other Ways Minors Can Build Credit
Credit cards are not the only way to build credit before age 18. A secured savings account or credit-builder loan through a credit union can also create a credit history. With a credit-builder loan, you deposit money into a savings account, and the credit union lends you that same amount. You make monthly payments on the loan, and the credit union reports your payments to the credit bureaus. After you repay the loan, you get your money back plus interest.
Some credit unions also offer youth savings accounts that report to credit bureaus. These accounts do not require a deposit or a loan; you straightforward open a savings account and make regular deposits. The credit union reports your account activity, which builds a credit history without any debt.
A parent or guardian can also co-sign a loan with you, though this is less common for minors. The co-signer is legally responsible if you do not pay, so they take on real risk. This option works better once you are 18 and have a reason to borrow — for example, to buy a car or pay for college.
Comparing Your Options Before Age 18
| Option | Age Requirement | What You Need | Credit Building | Risk Level |
|---|---|---|---|---|
| Authorized User on Parent's Card | Any age | Parent or guardian with a credit card | Yes, if issuer reports to bureaus | Depends on parent's payment habits |
| Credit-Builder Loan | Usually 18, varies by credit union | Deposit money; credit union co-signs | Yes, if credit union reports | Low; you control the money |
| Youth Savings Account | Any age | Parent or guardian; savings deposit | Yes, if credit union reports | Very low; savings account only |
| Secured Credit Card | 18 | Cash deposit ($200–$2,500) | Yes, if issuer reports | Moderate; you manage the card |
Questions to Ask Before Becoming an Authorized User
Before a parent or guardian adds you to their card, ask these questions to make sure it will actually build your credit. First, does the card issuer report authorized user accounts to all three credit bureaus? If they do not, the account will not show up on your credit report, and you will not build credit history. Second, what is the current balance and payment history on the account? If the account has missed payments or a high balance, being added will hurt your credit rather than help it.
Third, what is the credit limit, and is there a spending agreement? Discuss how much you can charge each month and what the card is for. Fourth, will the primary account holder let you check the balance online or through the app? You need to see what you have charged so you do not overspend. Finally, ask whether the account can be converted to your name when you turn 18, or whether you will need to open a new account.
Frequently Asked Questions
Can I get a credit card without a parent or guardian?
No. You must be 18 years old and have a Social Security number to open a credit card account in your own name. Before age 18, your only option is to become an authorized user on someone else's account.
Does being an authorized user hurt my credit if the account has a high balance?
Yes. A high balance on the account increases the credit utilization ratio, which lowers your credit score. This happens whether you charged the balance or not. Ask the primary account holder to keep the balance low or pay it down before adding you.
What if I turn 18 and want my own card but have no credit history?
If you were not an authorized user, you will likely need to open a secured credit card. This requires a cash deposit but does not require a co-signer or a credit history. After 6 to 18 months of on-time payments, you can convert to a regular card.
Can I remove myself from an authorized user account if the primary account holder misses payments?
You cannot remove yourself, but you can ask the primary account holder to contact the card issuer and request that you be removed. Once you are removed, the account stops appearing on your credit report, though the payment history you built while on the account remains.
Do I need to be 18 to open a credit-builder loan?
Most credit unions require you to be 18, but some allow minors with a parent or guardian as a co-signer. Call your local credit union to ask about youth credit-builder programs. Requirements vary by institution.
