How to Become an Authorized User on Someone Else's Credit Card

What it means to be an authorized user

An authorized user is someone who has permission to use someone else's credit card account. When you become an authorized user, the card issuer adds you to the account, usually sends you a card in your name, and you can make purchases that the primary account holder pays for. You are not responsible for the bill — the person whose name is on the account is.

Being an authorized user is different from being a co-signer or a joint account holder. A co-signer guarantees a loan but does not use it. A joint account holder shares legal responsibility for the debt. An authorized user has no legal obligation to pay, even if the account goes unpaid.

The main reason people become authorized users is to build credit history. When the primary account holder makes on-time payments and keeps the balance low, that positive history can show up on the authorized user's credit report — which can raise their credit score over time. This is why becoming an authorized user on a parent's or trusted family member's account is a common first step for young adults building credit.

Key Takeaways

• You can ask the primary account holder to add you to their card, and they contact the issuer directly — there is no separate form you fill out.
• The account's payment history and balance will appear on your credit report, so choose an account with a long record of on-time payments and low balances.
• You have no legal obligation to pay the bill, but you can still make purchases on the card if the primary holder gives you permission.
• Not all credit card issuers report authorized user accounts to the credit bureaus, so ask before you commit to the arrangement.
• You can ask to be removed from the account at any time, and the primary holder can remove you without your permission.

How the primary account holder adds you

The person whose name is on the card calls or logs into their online account with the credit card issuer and requests to add an authorized user. They will need to provide your full name, date of birth, and sometimes your Social Security number. The issuer then sends a new card to the address on file, usually within 7 to 10 business days.

You do not fill out any forms or contact the issuer yourself. The primary account holder makes the entire request. If they are unsure how to do it, they can call the customer service number on the back of their card — the issuer will walk them through the steps.

Some issuers allow the primary holder to set spending limits for authorized users, and some let them choose whether to report the account to the credit bureaus. If building your credit is the goal, ask the primary holder to confirm with the issuer that the account will be reported — not all issuers do this automatically.

What happens to your credit report

Once you are added as an authorized user, the credit card account appears on your credit report. This includes the account's age, credit limit, payment history, and current balance. If the account has been open for years and the primary holder has paid on time every month with a low balance, that positive history helps your credit score.

The boost depends on your starting point. If you have no credit history yet, adding an authorized user account can raise your score noticeably. If you already have several accounts, the effect is smaller. Credit bureaus weight recent activity and accounts you actively manage more heavily than accounts you are just added to.

If the primary account holder misses a payment or carries a high balance, that negative history also appears on your report and can lower your score. This is why it matters to choose an account with a strong payment record. You have no control over the account once you are added, so you are relying on the primary holder to keep paying on time.

Choosing the right account to join

Before you ask someone to add you, think about which account will help your credit most. Look for an account that has been open for several years, has a low balance relative to its credit limit, and has a clean payment history with no late payments. A card that has been open for 10 years and carries a $500 balance on a $10,000 limit is more valuable to your credit than a newer card with a high balance.

Ask the primary holder about the account's history before they add you. You can also ask them to check their credit report — they can see the account details there. If they are not sure, they can call the issuer and ask about the account's age and payment history.

Avoid accounts that are in collections, have recent late payments, or are about to be closed. These will not help your credit and may hurt it. If the primary holder is struggling with the account, becoming an authorized user on it will not solve their problem and will damage your credit instead.

What you can and cannot do as an authorized user

You can use the card to make purchases if the primary account holder gives you permission and sends you the card. You can shop online, in stores, or over the phone just like the primary holder can. However, you cannot change the account settings, request a credit limit increase, add other authorized users, or close the account. Only the primary holder can do those things.

You also cannot see the bill or make payments unless the primary holder gives you access to their online account. If you want to know the balance or payment due date, you have to ask them. This is by design — the primary holder maintains full control of the account.

If you want to use the card regularly, talk with the primary holder about how they want to handle it. Some families set up a system where the authorized user pays the primary holder back for purchases. Others treat it as a gift or a way to teach spending habits. Whatever the arrangement, it should be clear to both of you from the start.

Removing yourself or being removed

You can ask the primary account holder to remove you from the account at any time. They contact the issuer and request your removal — it usually takes a few days to process. Once you are removed, the account no longer appears on your credit report, though the history stays on your credit file for the time you were an authorized user.

The primary holder can also remove you without asking your permission. They do not need a reason, and they do not have to tell you in advance. If the relationship changes or they decide they no longer want you on the account, they can call the issuer and have you removed immediately.

Removing yourself does not hurt your credit score, even though the account disappears from your report. The positive history you built while on the account remains part of your credit file. However, if you were relying on that account to keep your credit score up, your score may drop slightly once it is no longer actively reporting.

Risks and things to watch for

The main risk of being an authorized user is that you have no control over the account. If the primary holder stops paying, misses a payment, or runs up a high balance, your credit score drops along with theirs. You cannot prevent this or fix it yourself — you can only ask them to pay or remove you from the account.

Another risk is that some issuers do not report authorized user accounts to all three credit bureaus. Your account might show up on Equifax but not on Experian or TransUnion. Before you commit to the arrangement, ask the primary holder to confirm with the issuer that the account will be reported to the bureaus that matter for your credit score.

Be cautious about becoming an authorized user on an account with a high balance or a history of late payments. The short-term credit boost is not worth the damage if the account goes unpaid. Stick with accounts that have a strong, clean history.

Frequently Asked Questions

Does being an authorized user hurt the primary account holder's credit?

No. Adding an authorized user does not change the primary holder's credit score or credit report. The account is still theirs, and adding you to it does not affect their credit in any way.

Can I be removed from an account without my permission?

Yes. The primary account holder can remove you at any time without telling you or asking your permission. If you think this might happen, ask them to let you know if they decide to remove you so you can plan ahead.

What if I want to use the card but the primary holder does not want me to?

That is between you and the primary holder. Being an authorized user means you have permission to use the card, but the primary holder can set rules about when and how you use it. If you disagree about how the card should be used, talk it through before you are added to the account.

Will becoming an authorized user show up on my credit report right away?

The account usually appears on your credit report within 30 to 45 days of being added. Credit bureaus update monthly, so there is a lag between when you are added and when it shows up. Your credit score may not change until the account appears on your report.

Can I become an authorized user if I have bad credit?

Yes. There is no credit check or credit requirement to become an authorized user. The primary holder just needs to request it. However, if you have bad credit because of unpaid accounts or collections, becoming an authorized user on a good account will help, but it will not erase the negative history already on your report.
