Age Requirements: How Old Do You Have to Be to Get a Credit Card?

Credit card access depends on your age and the type of account you’re pursuing. Understanding these age thresholds—and the reasoning behind them—is essential before you apply.

Starting Early: Authorized Users Have Lower Age Barriers

One of the most flexible paths to credit card access comes through becoming an authorized user on someone else’s account. This option opens doors for younger individuals, sometimes even before their teens.

As an authorized user, you receive your own physical card bearing your name, but the account remains linked to the primary cardholder’s credit line. The account holder maintains full financial responsibility for all purchases, including those made by authorized users.

Most major financial institutions impose minimal or no age restrictions for authorized users. Here’s how the major players compare:

• American Express: 13 years old
• Bank of America: No minimum age
• Capital One: No minimum age
• Chase: No minimum age
• Citi: No minimum age
• Discover: 15 years old
• U.S. Bank: 16 years old
• Wells Fargo: No minimum age

This approach offers a practical learning opportunity for younger individuals exploring credit management. However, supervision matters significantly during the learning phase. If an authorized user accumulates charges that go unpaid, the consequences fall directly on the primary account holder’s credit history. Many parents find it prudent to retain physical card possession during initial lessons, gradually allowing more independence as financial responsibility develops.

Adding a young person as an authorized user—even without handing over the physical card—can accelerate their credit history development, providing a head start before they apply for independent accounts.

Independent Accounts: The 18-Year Threshold

Once you reach 18, you gain the legal right to establish your own credit card account and independent credit line. However, this milestone comes with significant conditions.

Credit card applications universally require proof of sufficient income to demonstrate repayment capacity. For those between 18 and 21, the income sources accepted are notably restricted. Only employment income or educational scholarships and grants qualify. Third-party income—including parental gifts or allowances—doesn’t meet the threshold. This limitation traces back to the CARD Act of 2009, legislation specifically designed to prevent young adults from obtaining credit lines they lacked realistic means to repay.

Applicants without eligible income sources may still qualify by securing a cosigner—an individual with established credit willing to assume debt responsibility. However, few major credit card issuers accommodate cosigner arrangements. Credit unions, particularly local institutions, often provide more flexible alternatives.

The 21-Year Turning Point: Restrictions Ease

At 21, the income qualification landscape shifts dramatically. The restrictions constraining acceptable income sources essentially disappear. You may now include gifts, allowances, government benefits, and retirement income—essentially any income stream with a legitimate claim.

Beyond income flexibility, reaching 21 also expands your credit product options. While earlier applicants without credit histories face limitations, your growing options at this age include cards specifically structured for first-time cardholders, offering pathways that become increasingly accessible as you build credit history.

Building a Strong Foundation

Regardless of which path you pursue, financial education precedes application. Understanding credit card mechanics—interest rates, annual percentage rates, payment cycles, and the long-term consequences of debt accumulation—prevents costly mistakes. The time invested in learning basics before your first swipe pays exponential dividends compared to the years spent recovering from credit card debt mismanagement.
