How to add someone to your credit card
You add someone to your credit card by calling your card issuer, providing their name and Social Security number, and requesting they be added as an authorized user. The process takes minutes on the phone, though some issuers also allow it online through your account dashboard. The person you add does not need to be present, does not sign anything, and the card issuer handles all the paperwork — you straightforward confirm you want them to have access to the account.
The key thing to understand upfront: adding someone as an authorized user puts them on your existing account. They use a card linked to your credit line, your payment history, and your liability. You remain responsible for all charges they make. This is different from a joint account holder, who would have equal legal responsibility — authorized users do not.
Key Takeaways
- Call your card issuer's customer service number on the back of your card and ask to add an authorized user by name and Social Security number.
- The authorized user receives their own card in the mail but charges go to your bill and your credit report, not theirs.
- You can set spending limits on some cards, though not all issuers offer this feature — ask before you add the person.
- Removing an authorized user takes one phone call and stops them from using the card when ready, though the account history remains on both credit reports.
- Adding an authorized user may trigger a hard inquiry on your credit, though many issuers do not pull credit for this step.
What happens when you add an authorized user
Once you add someone as an authorized user, the card issuer mails them a card with their name on it within 7 to 10 business days. They can use that card to make purchases when ready, and those charges appear on your monthly statement under your account. You receive one bill for all activity, and you pay it in full.
The account history — both positive and negative — reports to both your credit report and the authorized user's credit report. If you pay on time, both credit scores benefit. If you miss a payment or carry a high balance, both credit scores are affected. The authorized user builds credit history without having opened the account themselves, which is why parents often add teenagers or spouses add partners with limited credit history.
The authorized user has no legal obligation to pay the bill. You are the account holder and you are responsible for all charges, regardless of who made them. If the authorized user runs up debt and you cannot pay it, the debt is yours to resolve.
How to call your card issuer and complete the request
Find the customer service number on the back of your credit card. Call during business hours and tell the representative you want to add an authorized user. Have ready the person's full name, date of birth, and Social Security number. Some issuers ask for their address as well.
The representative will confirm the information, may ask why you are adding them, and will tell you whether a hard inquiry will be pulled on your credit. Many major issuers — including Chase, American Express, and Discover — do not pull credit for authorized users, but some do. Ask before you confirm.
Once confirmed, the card issuer will mail the new card to the address on file for your account, or to a different address if you request it. You can usually see the authorized user in your online account within 24 hours, even before the physical card arrives. Some issuers allow you to add an authorized user through their mobile app or website instead of calling — check your account dashboard first.
Spending limits and controls you can set
Not all card issuers offer spending limits for authorized users, so this is not may provide. American Express, for example, allows you to set a monthly spending cap on each authorized user's card through your online account. Chase does not offer this feature on most personal cards. Discover offers it on some products. Call your issuer and ask whether this option is available before you add the person.
If your issuer does offer limits, you can usually set them online after the authorized user is added. You can also change or remove the limit at any time. The limit applies to that specific authorized user's card only, not to your own spending on the account.
If your issuer does not offer built-in limits, you have no way to restrict spending through the card system itself. Your only option is to monitor the account regularly and remove the authorized user if they spend more than you are comfortable with.
How adding an authorized user affects your credit
Adding an authorized user may trigger a hard inquiry on your credit report, which can lower your score by a few points temporarily. However, many of the largest issuers — Chase, American Express, Discover, and Capital One — do not pull credit for this step. Others do. Ask your issuer before you confirm the addition.
Once the authorized user is added, the account's payment history and balance report to both credit reports. A long account history with on-time payments helps both scores. A missed payment or high balance hurts both scores. The authorized user benefits from your good payment history without having to build it themselves, which is the main reason to add someone.
If you remove the authorized user later, the account history remains on both credit reports. It does not disappear from the authorized user's report just because they are no longer on the card. This is why adding a spouse or partner to a card can help their credit long-term, even if you later remove them.
Removing an authorized user
Call your card issuer and ask to remove the authorized user by name. The representative will confirm the request and the removal is usually when ready — the person can no longer use the card right away. The physical card they have becomes invalid, though they may not realize it until they try to use it.
The account history remains on both credit reports after removal. The authorized user's credit report will still show the account and its payment history, even though they are no longer on the card. This is permanent and cannot be undone by either of you.
If the authorized user has made charges that you dispute or do not recognize, removing them does not erase those charges from your bill. You are still responsible for paying them. If you believe fraud occurred, contact your issuer's fraud department separately.
When to add someone as an authorized user versus a joint account holder
Add someone as an authorized user when you want them to have access to the card but you want to keep full control and responsibility. You remain the only person legally liable for the debt. This is the right choice for teenagers, adult children, or spouses you want to help build credit without giving them equal ownership of the account.
A joint account holder (also called a co-applicant or co-owner) is a different arrangement entirely. Both people are equally responsible for the debt, both have equal access to the account, and both can make changes to it. Joint accounts are less common with credit cards than they are with bank accounts. If you want to add a spouse or partner as a true co-owner, you typically have to close the existing card and open a new joint account together. Most card issuers do not convert an existing account to a joint account.
Authorized user is the simpler, more common choice. It gives the other person a card and builds their credit without changing your legal position.
Frequently Asked Questions
Can an authorized user see my full account details and statements?
That depends on the card issuer. Some issuers give authorized users access to the full online account, including all statements and transaction history. Others restrict the authorized user's view to only their own charges. Call your issuer and ask what the authorized user will be able to see before you add them, especially if you want to keep certain transactions private.
What if the authorized user runs up charges I cannot pay?
You are legally responsible for all charges on the account, regardless of who made them. If you cannot pay, the debt becomes yours and affects your credit report. Your only recourse is to remove the authorized user and try to recover the money from them directly — the card issuer will not help you do that. This is why you should only add someone you trust completely.
Does adding an authorized user hurt my credit score?
A hard inquiry may lower your score by a few points temporarily, but many issuers do not pull credit for this step. Once the account is added, the authorized user's credit benefits from your on-time payments and low balance, just as your credit does. If you miss a payment or carry a high balance, both scores are hurt equally.
Can I add an authorized user if I have bad credit?
Yes. Your credit score does not prevent you from adding an authorized user. The card issuer may not pull credit at all for this step. However, if you have a high balance or missed payments on the account, adding an authorized user means they inherit that negative history on their credit report as well.
How long does it take for the authorized user to receive their card?
Most issuers mail the card within 7 to 10 business days. You can usually see the authorized user in your online account within 24 hours, and some issuers offer a temporary digital card number that can be used when ready. Ask your issuer whether a digital card is available while you wait for the physical card to arrive.
