How to Build Credit as a Teenager in 2026 (Under 18 and 18+)
Can You Build Credit Before 18?
You can't open your own credit card or loan before turning 18. Lenders require applicants to be at least 18 years old to enter a credit agreement. But that doesn't mean you have to wait until your 18th birthday to start building credit.
The most common way teens build credit before 18 is by becoming an authorized user on a parent's or guardian's credit card. When a parent adds you to their account, the account's history can appear on your credit report, giving you a head start.
Some credit-building services also allow minors to participate with parental consent, though options are more limited.
Best Ways to Build Credit as a Teenager
Here are the most effective strategies, organized by whether you're under or over 18.
Under 18: Become an authorized user. Ask a parent or guardian with good credit to add you to one of their credit cards. The card's payment history, credit limit, and age will appear on your credit report. You don't even need to use the card — just being on the account helps. Make sure the card issuer reports authorized users to the credit bureaus. Most major issuers like Chase, American Express, and Capital One do.
Under 18: Learn good habits now. Even before you have your own credit accounts, develop the habits that will serve you well. Understand how budgeting works, learn about interest rates, and practice living within your means. These skills matter more than any credit-building trick.
At 18: Open a credit builder card. Once you turn 18, you can get your own credit account. A credit builder card is designed specifically for people with no credit history. There's no credit check and no minimum score required. Each on-time payment builds your credit history independently. Self offers a Visa credit card with high approval rates — read our Self review for details.
At 18: Consider a credit builder loan. Self offers one of the most popular credit builder accounts, and Kikoff provides a no-interest credit account with no hard pull — check out our Kikoff review. Starting one at 18 alongside a credit builder card gives you both revolving and installment credit on your report.

At 18: Open a student credit card. If you're heading to college, student credit cards are designed for young adults with limited credit. They typically have lower credit limits and more forgiving approval standards.

Becoming an Authorized User as a Teen
This is the most powerful credit-building tool available to teenagers. Here's what you and your parent should know.
Choose the right account. The ideal card has a long history (several years or more), perfect payment record, and low utilization. A card your parent has had for 10 years with never a late payment will give you a strong foundation.
You don't need to carry the card. Being an authorized user doesn't mean you need to spend on the card. The account history benefits your credit whether you use the card or not.
The impact can be immediate. Once the card issuer reports you as an authorized user (usually the next billing cycle), the account appears on your credit report. If the account has years of positive history, your score can jump significantly.
There are risks to consider. If the primary cardholder misses payments or maxes out the card, it hurts your credit too. Only become an authorized user on an account that's well-managed.
Getting Your First Credit Card at 18
Once you turn 18, you're eligible for your own credit accounts. But under the CARD Act, if you're under 21, you either need to show proof of independent income or have a co-signer to get a traditional credit card.
Credit builder cards and secured cards often have different requirements. Many don't require proof of income and don't perform a credit check. This makes them the most accessible option for 18-year-olds.
When you get your first card, start with these rules. Use it for one or two small purchases each month. Pay the full balance before the due date every single time. Keep your utilization below 30% of your limit. Set up autopay so you never accidentally miss a payment.
Common Mistakes Teen Credit Builders Make
Applying for too many cards at once. Each application creates a hard inquiry that temporarily lowers your score. Start with one card and add more gradually.
Carrying a balance. Paying interest doesn't help your credit score. Pay in full each month.
Ignoring their credit report. Check your report regularly, even as a teen. Errors and identity theft can affect anyone.
Closing their first account. Your first credit account contributes to your average account age. Keep it open even after you get better cards.
Spending more than they can afford. A credit card is not free money. Only charge what you can pay off in full.
The Bottom Line
Building credit as a teenager gives you a meaningful advantage. Whether you start as an authorized user before 18 or open your first account right at 18, every month of positive history counts.
The earlier you start, the stronger your credit foundation will be when you need it for apartments, car loans, and more. Products like Self, Kikoff, and Current make it easy to get started at 18.
