The minimum age to have your own credit card
You must be at least 18 to get a credit card in your own name, even if you have a credit card cosigner.
The Credit CARD Act of 2009 placed some further restrictions on issuing credit cards to consumers who are 18 to 20. If you're under 21, a card issuer might ask you for additional verification information or a cosigner.
But consider whether your question is "How old do you have to be to get a credit card," or "How old do you have to be to use a credit card?" They're different.
You can use a credit card before the age of 18. If someone (like a parent) is willing to add you as an authorized user to their account, you can get a credit card even sooner. Credit card authorized users are able to make charges to a primary cardholder's account.
Age isn't the only factor credit card issuers consider. Your credit score is the key to credit card approval in most cases.
Your credit score is a number that rates how good you are at managing debt, among other things. When you make a debt payment, apply for a credit card, or take similar actions, you build credit history. Your credit history is recorded in your credit report. FICO uses the information on your credit report to calculate your credit score, or general risk to a lender. The better you are with making on-time payments, the better your credit history, credit report, and credit score.
If you're barely out of high school and haven't yet had any bills in your name, your credit history may be thin. You might not even have a credit score.
How to get your first credit card
Instead of asking how old you have to be to get a credit card, you're probably now thinking, how can I establish credit for the first time? Especially if no one will approve me for a credit card?
Don't worry -- there are ways to get a card, even if you have no credit score. Here's how.
Become an authorized user
First, you can get added to someone else's card as an authorized user. All the activity on that account, including the primary cardholder's, will typically show up on your credit report. If you keep the balance low and make payments on time, it should help you develop a good score.
Find a cosigner
Another option is to apply for a credit card with a cosigner (although not every card issuer allows a cosigner). Ideally, your cosigner should be someone with stellar credit. That way, you'll get approved based on your cosigner's record. But finding a cosigner may be easier said than done. Your cosigner effectively takes responsibility for making sure your charges are paid in full. Some typical candidates for a cosigner might include a parent, aunt, uncle, or older sibling.
Apply for a secured credit card or student credit card
Another option you might look into is applying for one of the best secured credit cards. With a secured credit card, you give the card issuer a cash deposit. Then you're allowed to charge purchases up to the amount you've put down. So if you give the issuer a $500 deposit, you can charge up to $500 on your credit card. A secured credit card lets you build a credit history with no credit score so you're eligible for a traditional credit card in the future.
College students might get approved for a student credit card. The best student credit cards are designed specifically for students. They work just like traditional credit cards. However, they typically come with lower credit limits and looser credit score and income requirements for approval. You might snag one if you have some type of income, even with a limited to nonexistent credit history.
