Establishing healthy credit early in life is invaluable, as it lays the foundation for financial stability. However, the Credit CARD Act of 2009 places restrictions on credit card access for young adults under 21, which can make it more challenging for younger students to start building credit independently.

Key Takeaways
-
Most major credit card companies don’t allow cosigners on credit cards.
-
Cosigners take on the risk of the cardmember and must meet eligibility criteria.
-
Alternatives to cosigning include becoming an authorized user, starting a joint account, and acquiring a secured credit card.
The Act requires individuals under 21 to have a steady income or a cosigner to qualify for a credit card. While some credit card companies permit a cosigner, which can be a parent or guardian, to help a student under 21 qualify for a card, this practice is not the standard. In fact, some major credit card issuers do not allow cosigners to access their student credit cards, including Discover®.
Students who might qualify for a card with a cosigner
For young adults aged 18 to 21, getting a credit card is still within reach, despite some protective measures. The Credit CARD Act of 2009 aims to shield young people from harmful credit practices but also provides clear paths to acquiring a credit card. Here’s the straightforward breakdown:
- Cosigner Option: If you're a college student in the 18 to 21 age group, you may be able to apply for a credit card with the help of a cosigner, such as a parent or guardian.
A cosigner agrees to cover your credit card payments if you can't, reducing the risk for the credit card issuer. However, it's important to note that not all credit card companies allow this option. For example, Discover is among the companies that do not permit cosigners for their credit cards.
- Proof of Income: If getting a cosigner isn't an option for you, demonstrating that you have a stable student income can also qualify you for a credit card. You'll need to show that you earn enough money independently to manage your credit card payments. This rule ensures that you’re able to handle credit responsibly on your own, without accumulating unmanageable debt.
Keep in mind that credit card companies vary in their requirements. While some may offer the possibility of applying with a cosigner, many don’t. For young adults without a cosigner, proving sufficient independent income becomes the key to obtaining a credit card.
Who can be a cosigner on a student credit card?
If you're considering cosigning for a student credit card, you need to meet specific criteria along with the primary applicant. As a cosigner, you're expected to have a more established credit history and take responsibility for the debt if the primary cardmember doesn't make payments. Typically, eligible cosigners are parents, legal guardians, or spouses who have a good credit score and stable income, ensuring you're financially capable of covering any potential liabilities.
Beyond these relationships, if you're an adult with a solid credit history and demonstrate the ability to manage credit effectively, you may also be a cosigner if the credit card issuer allows for one. It's crucial for you to understand that your credit will be equally affected by the account's activity. This highlights the importance of using credit responsibly and making payments on time.
What a cosigner should know before committing to a card with a student
Becoming a cosigner on a college student’s credit card is a big responsibility. When you agree to cosign, you promise to pay off the card if the student can't. This means that whatever happens with the card—whether it's good or bad—affects both your and the student's credit scores. Missed payments or high debt on the card could harm both of your credit histories.
It's important for you to be careful as a cosigner. You should monitor the account to make sure it's being used responsibly and that payments are made on time. Before you agree to cosign, it's a good idea to talk with the student about how to use the card wisely. Remember, cosigning isn't just about helping them get a credit card; it's about taking on shared responsibility for how the card is used and making sure it's paid off properly.
How long do you need to keep a cosigner on your student card?
A cosigner on a student credit card is usually needed until the student closes the account they have with the cosigner and opens a new account on their own. As the Federal Trade Commission explains, lenders are unlikely to release cosigners from a loan, as it may increase their risk.
Review the card issuer's terms before you cosign for a credit card to see if there’s a cosigner release option. If so, when the time is right for you to release from the credit card, contact the issuer to request a release.

Alternatives to student credit card cosigners
If you find yourself struggling to qualify for a credit card on your own and find that a cosigner option isn't available—since not all credit card issuers, including Discover, allow cosigners—don't lose hope. There are still practical ways to start building your credit.
One such method is through a secured credit card. Another strategy is to become an authorized user on another person's credit card.
Both options provide a pathway to build credit, especially when getting a cosigner is not an option. By taking a responsible approach to credit and choosing the right financial tools, you can lay the groundwork for a solid credit history.
Consider a secured credit card
A secured credit card may be an excellent option for college students without established credit. Unlike a regular credit card, a secured card requires a cash deposit from the cardmember, which typically equals the credit limit. If you don’t repay your balance on time, the card issuer may hold onto your deposit and close your account. This deposit means less risk for the card company, so it may be convenient to get this type of card if you have no credit or bad credit. There’s no credit score required to apply for a Discover it® Secured credit card.2
With a secured card, it's all on you–the credit you build is based on how you use the card. As long as your secured credit card activity is reported to the major credit bureaus, you can build your credit history with responsible use.3 By creating smart habits, like making on-time payments, you could eventually qualify for an unsecured credit card, which may further strengthen your credit history. Some card issuers, like Discover, allow you to get your deposit back after six consecutive on-time payments and six months of good status on all your credit accounts.4
Did you know?
With a secured credit card from Discover, you may earn rewards as you build healthy credit habits. Instead of paying for your rewards with annual fees, keep more money in your pocket. Every Discover Card lets you earn rewards on every purchase, with no annual fee.
Become an authorized user on someone else’s credit card
Being an authorized user on someone else's credit card may be an option to start building your own credit history and score. As an authorized user, you may get a card linked to someone else's account, but, unlike a cosigner, you're not responsible for paying the bill. The way the main cardmember uses the card—like making payments on time and not using too much of the credit limit—will show up on your credit report too. If the main cardmember doesn't manage the card well, it could hurt your credit score. So, if they use the card responsibly, it can help build your credit score. Your activity on the account may affect the primary cardmember’s credit score too.
Discover allows cardmembers to add authorized users who are 15 and older to their accounts. Once an authorized user is ready to apply for their own credit card, their credit history may help them qualify for better terms.
Apply for a joint credit card account
Applying for a joint credit card account with someone else, like a friend or family member, can be another strategy to build your credit history and score. In a joint account, both people have equal responsibility for managing the account. This is different from having a cosigner, where the cosigner only becomes liable for payments if the primary account holder fails to make them. If both of you use the card wisely and make payments on time, it can help improve both of your credit scores. However, if one person mismanages the card, it could negatively affect both of your credit scores.
It's important to know that not all credit card companies offer the option for joint accounts. For example, Discover doesn’t allow joint credit card accounts. This means you need to check with the credit card company first to see if they allow joint accounts before you plan to apply with someone else.
The bottom line
Getting a credit card when you're a young college student or just starting with credit can be tough. But remember, if you’re looking to cosign with someone on a credit card, it's a big responsibility for both of you. If getting a cosigner isn't an option, there are other ways to begin building credit history, like secured credit cards or being an authorized user on someone else's card. Whatever way you choose, the most important thing is to use credit wisely and make sure everyone understands their responsibilities.
