How to add someone to your credit card

You can add someone to your credit card account in one of two ways: as an authorized user or as a joint account holder. The difference matters because it changes who is legally responsible for the debt and what happens to the account if you die or become unable to manage it.

Most people add a spouse, adult child, or trusted family member as an authorized user. The cardholder — you — remains the account owner and responsible for all charges. The authorized user gets their own card with their name on it and can make purchases, but they have no legal obligation to pay the bill. A joint account holder, by contrast, is equally responsible for the debt and has equal control over the account.

The process itself is straightforward: call your card issuer, go online to your account portal, or visit a branch if you have a bank-issued card. You will need the person's full name, date of birth, and Social Security number. Most issuers add an authorized user within one business day.

Key Takeaways

  • Authorized users can use the card but are not legally responsible for the debt; the primary cardholder remains liable for all charges.
  • Joint account holders share equal responsibility for the debt and equal control over the account, and both appear on credit reports.
  • You can add an authorized user by phone, online portal, or in person at a bank branch, and most issuers complete the process within one business day.
  • Adding an authorized user may help build their credit history if the issuer reports the account to the credit bureaus in their name.
  • You can remove an authorized user at any time through the same channels you used to add them, and the change takes effect immediately.

Authorized user vs. joint account holder

An authorized user is someone you permit to use your credit card, but the account remains in your name only. You receive the bill, you make the payments, and you are responsible for any charges the authorized user makes. The authorized user's name appears on their card, but not on the account statement or billing documents — those go to you. If the authorized user runs up charges and you cannot pay, the debt is yours to handle.

A joint account holder is a co-owner of the account. Both names appear on the account, both receive statements, and both are equally liable for the full balance. If one joint holder stops paying, the card issuer can pursue the other for the entire debt. Joint accounts are less common now because of this shared liability, but some couples and business partners still use them.

Most card issuers do not offer a true joint account option anymore. If you want to add someone with equal control and responsibility, you may need to open a new account together instead. Check with your issuer about what they actually offer — the terminology varies.

Steps to add an authorized user by phone

Call the customer service number on the back of your credit card. Have the following information ready: the person's full legal name, date of birth, and Social Security number. Some issuers also ask for their address, though they may already have yours on file.

Tell the representative you want to add an authorized user. They will confirm your identity by asking security questions or requesting your account PIN. Once verified, provide the authorized user's information and confirm the spelling of their name — this is how it will appear on the card.

Ask the representative three things before you hang up: when the new card will arrive, whether the issuer reports authorized user accounts to credit bureaus (and in whose name), and what the authorized user's credit limit will be. Some issuers set it at your full credit limit; others let you set a lower limit. If you want to restrict spending, ask to set a cap now.

Adding an authorized user online

Log into your credit card account on the issuer's website or mobile app. Look for a section labeled "Manage Account," "Account Settings," "Authorized Users," or "Add User" — the exact wording varies by issuer. Click that section.

Enter the authorized user's full legal name, date of birth, and Social Security number. Some issuers ask for their address as well. Review the information for accuracy before submitting, because errors in the name or SSN can delay the card's arrival or cause it to be issued under the wrong name.

After you submit, you will usually see a confirmation message with an estimated delivery date for the new card. The authorized user should receive their card within 7 to 10 business days. Some issuers offer the option to add a temporary digital card to a mobile wallet immediately, so the authorized user can make purchases before the physical card arrives.

What happens to credit reports when you add an authorized user

Whether adding an authorized user affects their credit report depends on the card issuer. Some issuers report authorized user accounts to all three credit bureaus (Equifax, Experian, and TransUnion) in the authorized user's name. Others report only to some bureaus, and some do not report at all.

If the issuer does report the account, the authorized user's credit report will show the account's payment history, credit limit, and balance. This can help build their credit history if the account is in good standing — on-time payments and low balances help their credit score. If the account has missed payments or high balances, it can hurt their score instead.

Before you add someone as an authorized user with the intention of helping their credit, contact the issuer and ask directly whether they report authorized user accounts to the credit bureaus. Do not assume they do. Some major issuers like Chase, American Express, and Capital One report authorized users to the bureaus, but policies vary and change. Getting a clear answer now prevents disappointment later.

Setting spending limits for an authorized user

Many issuers let you set a separate credit limit for an authorized user, lower than your own. This is useful if you want to give someone access to the card for specific purchases — a teenager for gas and groceries, or an adult child for emergencies — without exposing yourself to unlimited charges.

You can usually set or change the authorized user's limit through your online account or by calling customer service. Some issuers allow you to set different limits for different types of purchases (groceries, gas, online shopping), though this feature is less common. Ask your issuer what options they offer.

Keep in mind that a spending limit is a control tool, not a legal protection. If an authorized user exceeds their limit, you are still responsible for paying the charge. The limit is meant to prevent accidental overspending, not to shield you from intentional misuse.

Removing an authorized user

You can remove an authorized user at any time, through the same channels you used to add them: phone, online account portal, or in person at a branch. Call customer service, log into your account, or visit a branch and ask to remove the authorized user. Provide their name and confirm your identity.

The removal takes effect immediately. The authorized user can no longer use the card, and any card in their possession becomes invalid. The account will no longer appear on their credit report going forward, though the payment history that was already reported will remain on their credit report for seven years (the standard reporting period for account history).

If you are removing an authorized user because of a dispute or concern about their spending, consider also reviewing your account for any unauthorized charges. If you find charges you did not authorize, report them to the issuer as fraud or dispute them through your account portal.

Frequently Asked Questions

Can I add an authorized user without their Social Security number?

Most issuers require a Social Security number to add an authorized user because they need to verify identity and may report the account to credit bureaus. Some issuers accept an Individual Taxpayer Identification Number (ITIN) instead. Call your issuer to ask what forms of identification they accept.

Will adding an authorized user hurt my credit score?

Adding an authorized user should not hurt your credit score. The issuer does a soft inquiry (which does not affect your score) to verify the person's identity. Your credit report and score are not directly affected by adding someone else to your account.

Can an authorized user see my full account balance and payment history?

That depends on the issuer. Some issuers give authorized users access to the full account online, including balance and payment history. Others restrict what authorized users can see. If privacy is a concern, ask your issuer what information the authorized user will have access to before you add them.

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

If you close the credit card account, any authorized user cards become invalid immediately. The authorized user can no longer use them. If you want to keep the account open but remove just the authorized user, you can do that separately.

Can I add an authorized user who is under 18?

Most issuers require authorized users to be at least 18 years old. Some allow younger teenagers (16 or 17) with parental consent. Check your issuer's policy if you want to add a minor. Even if they allow it, the minor cannot be held legally responsible for charges, so you remain fully liable.
