You can add someone to your credit card in two ways, and they work very differently

The two main options are authorized user and joint account holder. An authorized user gets a card in their name but you stay responsible for all charges. A joint account holder shares legal responsibility for the debt with you — you both owe the full balance, and both of your credit reports are affected. Most people add a spouse, adult child, or family member as an authorized user. Joint accounts are less common and carry real risk if the other person doesn't pay their share.

The process itself is simple: call your card issuer, give them the person's name and date of birth, and they'll mail a card. But before you do, you need to understand what happens to their credit, what happens if they overspend, and whether you can remove them later.

Key Takeaways

  • An authorized user can use your card but you remain the sole account owner and are responsible for all charges, while a joint account holder shares both the card and the legal debt.
  • Adding someone as an authorized user may help their credit score if the card reports to the credit bureaus and has a low balance, but it can also hurt their score if the balance is high or if late payments occur.
  • You can remove an authorized user by calling your card issuer, but removing a joint account holder requires their consent and may involve closing the account entirely.
  • The person you add will see all transactions on their statement and can make purchases up to your credit limit, so set clear spending rules before you hand over the card.

Authorized user versus joint account holder: which one to choose

An authorized user is someone you add to your existing account. They get a card with their name on it and can make purchases, but the account stays in your name. You receive the bill, you make the payments, and you're legally responsible for everything charged to that card. The authorized user has no obligation to pay anything — that's entirely on you. If they max out the card, you owe it. If they don't pay and the account goes to collections, it shows on your credit report, not theirs.

A joint account holder is a co-owner of the account from the start. Both names appear on the account, both of you receive statements, and both of you are legally responsible for the full balance. If one person charges $5,000 and doesn't pay, the other person owes the full $5,000. Both credit reports are affected by the account's payment history and balance. Joint accounts are typically used between spouses or long-term partners who manage finances together.

Choose authorized user if you want to give someone access to your card while keeping full control and responsibility. Choose joint account if you're in a committed partnership and want to share both the benefits and the obligations of the account.

How adding an authorized user affects their credit score

When you add someone as an authorized user, the account appears on their credit report if your card issuer reports to the credit bureaus. Most major issuers do report authorized user accounts, but not all — call and ask before you add them if credit impact matters.

If the account helps their credit, it's usually because it adds a longer payment history or lowers their overall credit utilization (the percentage of available credit they're using). If your card has a $10,000 limit and you carry a $1,000 balance, that's 10 percent utilization, which is good. If you carry a $8,000 balance, that's 80 percent utilization, which hurts their score. The authorized user's score can improve or worsen depending on how you use the account.

Late payments on the account also show up on their credit report. If you miss a payment, it damages their credit score even though they didn't make the charge and didn't miss the payment themselves. This is why authorized user status only makes sense if you have a solid payment history and plan to keep it that way.

What happens if an authorized user overspends or stops paying

You are responsible for all charges, period. If the authorized user runs up a $3,000 balance and then stops using the card, you owe that $3,000. The card issuer will contact you for payment, not them. If you don't pay, the account goes delinquent and shows on your credit report. The authorized user faces no legal consequence because they were never responsible for the debt in the first place.

This is why you should only add someone you trust completely. Set clear rules about the card before you hand it over: what it's for, what the spending limit is, and whether they should ask permission before large purchases. Some people add an authorized user with a very low credit limit to prevent overspending — ask your issuer if you can set a limit lower than your overall card limit.

If the authorized user starts making charges you didn't authorize or can't afford, you can remove them immediately by calling your issuer. The card in their name stops working right away, though they may still have the physical card. You remain responsible for any charges they made before removal.

How to add an authorized user to your credit card

Call the customer service number on the back of your credit card. Tell them you want to add an authorized user. They'll ask for the person's full name and date of birth. Some issuers also ask for their Social Security number, though not all. The issuer will confirm the person's address and may ask security questions to verify your identity.

The card will be mailed to the address on file for the account — usually your address, not theirs. If you want the card sent to a different address, ask the representative to update the mailing address before they process the request. The card typically arrives within 5 to 10 business days.

Once the card arrives, the authorized user can activate it by calling the number on the back or using the issuer's app or website. They don't need to do anything else — they can start using it immediately. You'll see all their charges on your statement.

Removing an authorized user and closing a joint account

Removing an authorized user is straightforward: call your card issuer and ask them to remove the person by name. The card in their name stops working immediately, though they may still have the physical card in their possession. The account stays open in your name, and you keep using it normally. The removal shows on both your credit report and theirs, but the account history stays on both reports.

Removing a joint account holder is much harder. Because they're a co-owner, they have legal rights to the account. Most issuers won't remove a joint holder without their consent. Your options are to ask them to agree to removal, or to close the account entirely and open a new one in your name alone. Closing the account affects both credit reports and may lower your credit score because it reduces your available credit.

If you're in a situation where you need to remove a joint account holder and they won't cooperate, contact the card issuer to understand your options. Some issuers have procedures for disputes between account holders, but these are rare and may require documentation.

Adding a spouse or family member: what to consider first

Before you add anyone, think about why you're doing it. Are you trying to help them build credit? Give them access to emergency funds? Share household expenses? Each reason points to a different choice.

If you're trying to help a young adult or family member build credit, authorized user status can work — but only if you have good credit yourself and keep the balance low. Their score will improve along with yours. If your credit is poor or your balance is high, adding them as an authorized user will hurt their score instead of helping it.

If you're sharing household expenses with a spouse, a joint account makes sense because you're both using the card and both benefiting. If you're just giving a family member access to your card for occasional use, authorized user is safer because you keep full control.

Talk to the person before you add them. Let them know what the card is for, what the limit is, and what you expect them to charge. If they're being added to help their credit, explain how it works and that late payments will hurt them too. If they're being added for emergency access, make sure they know how to use the card and when to use it.

Frequently Asked Questions

Can I add someone to my credit card without their permission?

Technically yes for authorized user status, but you shouldn't. The card will be mailed to your address, so they won't know until you give it to them. However, the account will appear on their credit report, and they have a right to know that their credit is being affected. Adding someone without their knowledge can damage trust and may create legal problems if they later dispute the charges.

Will adding an authorized user hurt my credit score?

Not directly. Adding an authorized user doesn't change your credit limit, your balance, or your payment history. However, if the authorized user makes large charges that increase your balance, that can hurt your score because your utilization goes up. Your score is based on your account behavior, not theirs.

What's the difference between an authorized user and a cosigner?

A cosigner is someone who signs a loan or credit application with you and shares responsibility for the debt from the start. An authorized user is added to an existing account after it's already open. Cosigners are typically used when someone is applying for credit for the first time or has poor credit. Authorized users are added later to give someone access to an existing card.

Can I set a spending limit for an authorized user?

Some card issuers allow you to set a limit lower than your overall credit limit, but not all. Call your issuer and ask if they offer this feature. If they do, you can cap what the authorized user can spend in a single transaction or per month. This doesn't prevent overspending entirely, but it reduces the risk.

What happens to the authorized user's card if I close my account?

The authorized user's card stops working immediately. The account closes on both of your credit reports. If you want to keep the account open but remove them, call and remove them without closing the account — that way your credit history stays intact and only their access is cut off.
