How Old Do You Have to Be to Have Credit?

Credit plays a significant role in personal finance, influencing major life events such as securing housing, purchasing vehicles, or even obtaining certain types of insurance. It represents a borrower’s trustworthiness and capacity to manage financial obligations. Building a positive credit history involves demonstrating responsible borrowing and repayment habits over time. This financial track record is summarized in a credit score, a numerical representation that lenders use to assess risk.

The Legal Minimum Age for Credit

In the United States, individuals can legally enter into contracts, including credit agreements, once they reach 18 years of age. While this permits an 18-year-old to apply for a credit card, federal regulations introduce additional requirements for those under 21. The Credit Card Accountability Responsibility and Disclosure (CARD) Act of 2009 significantly impacted credit card access for young adults. This law generally prohibits credit card issuers from granting accounts to individuals under 21 unless they can demonstrate an independent means of repaying the debt or have a co-signer.

To satisfy the independent income requirement, an applicant aged 18 to 20 must prove they have sufficient income to make minimum payments. This income can come from a job, business, or regular allowances, but it must be verifiable and belong solely to the applicant, not a parent or partner. While the CARD Act allows for a co-signer, most major credit card issuers no longer offer this option for standard credit cards, making proof of independent income the more common path for young applicants.

Building Credit Before Age 21

Individuals under 21 can begin to establish a credit history through indirect or assisted methods. One common strategy is becoming an authorized user on another person’s credit card account. As an authorized user, you receive a card linked to the primary account holder’s credit line and can make purchases, but you are not legally responsible for the payments. This can help build your credit history if the primary cardholder manages the account responsibly, as their payment history and credit utilization may be reported to credit bureaus under your name. Some card issuers have minimum age requirements for authorized users, with some allowing individuals as young as 13 or 15.

Another avenue for building credit involves co-signed loans, though co-signing for credit cards is less common than for other loan types. A co-signer agrees to take on legal responsibility for the debt if the primary borrower fails to make payments. While this can help a young person qualify for a loan they might not otherwise obtain, it carries substantial risk for the co-signer, as missed payments will negatively impact both parties’ credit scores. Student loans, particularly federal ones, can also contribute to a credit history. Making on-time payments on student loans, which are a form of installment credit, is reported to credit bureaus and helps establish a positive payment history.

Establishing Independent Credit

Once an individual reaches 18, they can apply for credit independently, though credit cards for those under 21 have specific income or co-signer requirements. Student credit cards are tailored for college students, often featuring more lenient approval criteria and lower credit limits. These cards still require proof of income for applicants under 21.

Secured credit cards are another accessible option, particularly for those without a credit history or with a lower credit score. These cards require a security deposit, typically ranging from a few hundred dollars, which often serves as the credit limit. This deposit reduces issuer risk. Consistent, on-time payments and keeping the balance low with a secured card can help build a positive credit history, allowing for a transition to an unsecured card and deposit return over time. Small personal loans or credit-builder loans, where funds are held in a savings account until the loan is repaid, can also help establish a payment history, provided the lender reports to credit bureaus. During the application process, lenders assess factors like income and ability to repay.
