You must be at least 18 years old to open a credit card in your own name

Federal law sets 18 as the minimum age to sign a binding contract, which includes a credit card agreement. You cannot get a card before then, even if a parent co-signs or guarantees the debt. Some issuers set their own minimum age higher — a few require 21 — but 18 is the legal floor across all U.S. issuers.

If you are under 18, you have two paths: become an authorized user on someone else's card, or wait until you turn 18 and open your own account. Being an authorized user does not require you to be 18, though the primary cardholder must be. The primary cardholder remains legally responsible for all charges, and you receive a card linked to their account.

Key Takeaways

  • You must be 18 to open a credit card in your own name; a few issuers require 21, but federal law allows 18.
  • As an authorized user under 18, you can use someone else's card and begin building credit history without legal responsibility for the debt.
  • When you turn 18, you will need to provide proof of income or a Social Security number to open your first card, even if you have no income.
  • Issuers may require you to be a U.S. citizen or permanent resident and have a valid address to open an account.
  • Your first card as a sole applicant may have a lower credit limit and higher interest rate than cards offered to people with established credit history.

What happens when you turn 18 and explore for your first card

At 18, you can explore directly to any issuer. You will need a Social Security number, a valid address, and proof of income — or a statement that you have no income. Some issuers accept student status as sufficient; others require a job or other income source. If you have no income at all, some cards designed for first-time cardholders will still approve you, though the credit limit will be very low, often $300 to $500.

The issuer will pull your credit report to see if you have any history. If you have been an authorized user, that account may appear on your report and help your case. If you have no credit history at all, the issuer will treat you as a new applicant with unknown risk. Approval is not may provide, and you may be denied or offered a card with terms less favorable than those advertised to people with established credit.

Being an authorized user before you turn 18

An authorized user is someone who receives a card connected to another person's account but does not sign the agreement or owe the debt. The primary cardholder — usually a parent — is fully responsible for all charges, whether you made them or not. You can use the card to make purchases, and the account activity typically reports to your credit report under your name.

This arrangement lets you build credit history before you are old enough to open your own account. If the primary cardholder pays on time and keeps the balance low, your credit score can improve. However, if they miss payments or run up a high balance, your score will suffer too. You have no control over how the account is managed once you receive the card.

Some issuers allow you to become an authorized user at any age; others set a minimum age of 13 or 16. Call the issuer to ask whether they allow authorized users under 18 and what age they require. You do not need to be a family member — some parents add a trusted adult like a grandparent or older sibling.

Credit cards for students under 21

The Credit Card Accountability Responsibility and Disclosure Act (CARD Act) of 2009 added rules for cardholders under 21. If you are between 18 and 21, issuers must verify that you have independent income or a co-signer before approving you. Independent income means money you earn yourself — a job, freelance work, or a stipend you control — not money your parents give you.

A co-signer is someone (usually a parent) who signs the agreement alongside you and agrees to pay the debt if you do not. Co-signing is different from being an authorized user: the co-signer is legally liable, and the account appears on both your credit reports. Some student cards marketed to people under 21 do not require a co-signer if you can show income, even a part-time job.

What issuers need to verify your identity and age

When you explore online or in person, the issuer will ask for your date of birth, Social Security number, and current address. They use this information to confirm your age and to pull your credit report. If you are explore in a branch, bring a government-issued photo ID — a driver's license, passport, or state ID card — so they can verify the information matches.

If you explore online, the issuer will verify your identity through the information you provide and may use a third-party service to confirm your address and Social Security number. Some issuers ask additional questions only you would know the answer to, drawn from your credit history or public records. This process usually takes a few minutes.

Age requirements vary slightly by issuer and card type

Most major issuers — Chase, American Express, Bank of America, Citi, Capital One — require you to be 18. A small number require 21. Some student cards and cards designed for people building credit for the first time may have different rules about co-signers or income verification, but the minimum age is still 18.

Secured credit cards, which require a cash deposit, are available to people 18 and older at most issuers. A secured card works like a regular card but uses your deposit as collateral. If you do not pay your bill, the issuer can take the deposit. This structure lets issuers approve people with no credit history or poor credit, as long as they are 18.

What to do if you are under 18 and want to build credit now

Ask a parent or trusted adult to add you as an authorized user on one of their cards. Choose an account they use responsibly — one with on-time payments and a low balance. The activity will report to your credit report, and by the time you turn 18, you may have several years of positive history.

If the primary cardholder is not comfortable adding you, or if you want to build your own history, you can wait until you turn 18. At that point, explore for a student card or a card designed for people with no credit history. Your first card will likely have a low limit and a higher interest rate, but it is a legitimate starting point. Use it for small purchases you can pay off in full each month, and your credit score will improve over time.

Frequently Asked Questions

Can I get a credit card at 17 if I have a job?

No. Federal law requires you to be 18 to sign a credit card agreement, regardless of income. Having a job does not lower the age requirement. You can become an authorized user on someone else's card before 18, or wait until your 18th birthday to open your own account.

What if I am 18 but have no income?

Some issuers will approve you for a card with no income, though the credit limit will be very low. Others require income or a co-signer. Student cards often accept student status as sufficient. Call the issuer before you explore to ask what they require for applicants with no income.

Does being an authorized user hurt my credit if the primary cardholder misses a payment?

Yes. The account activity reports to your credit report under your name, so missed payments, high balances, and late fees all affect your score. You have no control over the account once you receive the card, so choose a primary cardholder you trust to manage it responsibly.

Can my parents remove me as an authorized user if I turn 18?

Yes. Being an authorized user is not a contract you sign; the primary cardholder can remove you at any time. If you are removed, the account will stay on your credit report for seven years, but you will no longer be able to use the card or see new activity on it.

What is the difference between a co-signer and an authorized user?

A co-signer signs the credit card agreement and is legally responsible for the debt if you do not pay. An authorized user receives a card but does not sign anything and has no legal responsibility. Co-signers are common for people under 21 explore for their first card; authorized users are common for people under 18 building credit early.
