The short answer: not on their own, but with a parent or guardian co-signing, yes
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. However, a parent or guardian can add a minor as an authorized user on their existing card, or in some cases co-sign for a card designed for teens. These are two different paths with different outcomes for building credit.
The reason for the age requirement is legal: minors cannot enter into binding contracts, and a credit card agreement is a contract. Lenders also want someone with established credit history and legal responsibility for the debt. That said, getting a minor connected to credit early—the right way—can set them up to build credit before they turn 18.
Key Takeaways
- A minor can become an authorized user on a parent's credit card, which may help build their credit history if the card issuer reports authorized user activity to credit bureaus.
- Some banks offer teen checking accounts with debit cards, which teach spending habits but do not build credit because debit is not a credit product.
- A few card issuers offer co-signed credit cards for teens 16 and older, where the parent is legally responsible for the debt.
- Adding a minor as an authorized user does not require them to have their own income or credit history, but the parent's payment behavior determines whether it helps or hurts their credit.
- Once a minor turns 18, they can open their own card, but being an authorized user first gives them a head start on credit history.
Authorized user: the easiest path, with a catch
When you add a minor to your credit card as an authorized user, the card issuer sends them a card in their name, and they can use it. The parent remains the account holder and is legally responsible for all charges. This is the most common way minors get connected to credit.
The catch is that not all card issuers report authorized user accounts to the three major credit bureaus (Equifax, Experian, and TransUnion). If the issuer does not report it, the minor builds no credit history. Before adding a minor, call the card issuer and ask directly: "Do you report authorized user accounts to credit bureaus?" Get the answer in writing if possible. Major issuers like Chase, American Express, Capital One, and Discover do report authorized user activity, but smaller banks and some store cards do not.
If the issuer does report, the minor's credit file will show the account's payment history, credit limit, and balance. This means late payments hurt their credit too. If you miss a payment, it appears on both your credit report and theirs. This is why authorized user status works best when the parent has strong payment habits.
Teen checking accounts and debit cards: not credit
Many banks market teen checking accounts with debit cards as a way to teach money management. These are useful for that purpose—they let a minor practice spending and saving without risk—but they do not build credit. A debit card draws from money already in the account; it is not a loan, so credit bureaus do not track it.
Debit cards are a good first step for learning to manage money, but they should not be confused with credit-building tools. A minor can have both: a debit card for everyday spending and authorized user status on a parent's credit card for credit history. The two serve different purposes.
Co-signed credit cards for teens: rare but available
A small number of card issuers offer credit cards designed for minors 16 or older, with a parent or guardian as a co-signer. Co-signing is different from authorized user status: the co-signer is legally responsible for the debt, and the minor's own credit report is built from the start. The minor is the primary account holder, not an add-on.
Discover and Capital One have offered co-signed student cards in the past, though availability changes. These cards typically have lower credit limits (often $500 to $2,500) and higher interest rates than standard cards. The point is not to get a good rate; it is to build credit under supervision. Before pursuing this route, check the current offerings from major issuers or ask your bank whether they offer a co-signed option for minors.
Co-signed cards report to all three credit bureaus and appear on both the minor's and co-signer's credit reports. This means the minor's payment behavior affects their own credit score from day one, which is more powerful for building history than authorized user status—but also riskier if payments are missed.
What happens when a minor turns 18
Once a minor reaches 18, they become a legal adult and can open their own credit card. If they were an authorized user or co-signer on a parent's account, that history stays on their credit report. This gives them a head start: they have a credit history before they ever applied for their own card, which can mean better approval odds and lower interest rates.
At 18, a young adult can also request to become the primary account holder on a card they were authorized on, though not all issuers allow this. More commonly, they will open a new card in their own name. The old authorized user account remains on their credit report and continues to help their score as long as the parent keeps paying on time.
Building credit as a minor: what actually matters
The goal of adding a minor to credit early is to give them a credit history before they need one. Credit history is the foundation of a credit score, and a credit score affects loan rates, apartment applications, and sometimes even job prospects later. Starting at 16 or 17 gives them years to build this before they apply for their first car loan or student loan at 18 or 19.
The most important thing is that the account stays in good standing: on-time payments, low balance relative to the credit limit, and no missed or late payments. A minor does not need to use the card much—even small, regular charges paid off in full each month help. The goal is activity and reliability, not spending.
If a parent's credit is poor or they have a history of late payments, adding a minor to their card can hurt the minor's credit instead of helping it. In that case, waiting until the parent's credit improves, or exploring a co-signed card with a different co-signer, may be better.
Frequently Asked Questions
Does a minor need a Social Security number to be an authorized user?
Most card issuers require a Social Security number for authorized users, but some allow an Individual Taxpayer Identification Number (ITIN) or will issue a card without one if the minor is a dependent on the parent's tax return. Call the card issuer to ask what they accept before you add the minor.
Can a minor use the card without the parent's permission?
Yes, once the card is issued, the minor can use it. This is why it matters to set clear rules beforehand about what the card is for and what spending is allowed. Some parents set a spending limit by agreement or monitor the account regularly online.
What happens to the authorized user account if the parent closes the card?
When the primary account holder closes a credit card, the authorized user card stops working. However, the account history remains on the minor's credit report for up to 10 years, which continues to help their credit score if the account was in good standing.
Can a minor get their own card if they have a job?
No. Income does not change the age requirement. A minor must be 18 to open a credit card in their own name, regardless of whether they work. However, having a job and income makes it easier to open a card at 18, and it shows responsibility to a lender.
Is being an authorized user better than a co-signed card?
Authorized user status is simpler and lower-risk for both parent and minor. A co-signed card builds the minor's own credit faster but makes the minor the primary account holder, so their mistakes directly damage their credit. Choose authorized user status for younger teens or if the goal is gentle introduction to credit; choose co-signed if the teen is older and ready for more responsibility.
