Most credit card issuers do not allow cosigners, but you have other options that accomplish the same goal
Credit card companies typically do not offer cosigner arrangements the way banks do for loans. A cosigner — someone who signs a contract and shares legal responsibility for debt — is not a standard feature on credit cards. Instead, card issuers use different structures: an authorized user, a joint account holder, or in some cases, a guarantor who is not listed on the card itself. Which option works depends on what you are trying to accomplish and which issuer you are working with.
The reason cosigners are rare on credit cards is structural. Credit card debt is unsecured, meaning the issuer has no collateral to seize if you do not pay. A mortgage lender or auto lender can repossess the house or car. A credit card issuer can only pursue collection and damage your credit score. Because of this, card companies rely on credit scores and income verification rather than a second person's promise to pay.
Key Takeaways
- Authorized users can use the card but typically have no legal responsibility for the debt, and their credit history does not affect approval.
- Joint account holders share full legal responsibility and both names appear on the account, making this the closest equivalent to a cosigner arrangement.
- Not all issuers offer joint accounts; many allow only authorized users, so you need to contact the card company directly to learn what they support.
- Adding an authorized user or joint holder does not may provide the primary cardholder will be approved if they would not may have access to alone.
- An authorized user's credit score improves if the account is paid on time, but their score can also be damaged if the account falls behind.
Authorized users versus joint account holders
An authorized user is someone you add to your existing credit card account who can use the card but does not sign the original agreement. You remain the sole person responsible for paying the bill. The authorized user's credit report may show the account (depending on the issuer), which can help their credit score if the account is managed well, but they have no legal obligation to pay if you do not.
A joint account holder is different: both people sign the account agreement and both are legally responsible for the full balance, regardless of who made the charges. Both names appear on the card and the billing statement. If one person does not pay, the issuer can pursue the other. This is the closest structure to a traditional cosigner arrangement, though credit card companies rarely use the word "cosigner."
Most major issuers — including Chase, Bank of America, American Express, and Discover — allow authorized users on most cards. Joint accounts are less common. Some issuers offer them on certain products; others do not offer them at all. You will need to contact the card company to ask whether joint accounts are available for the specific card you want.
When authorized users make sense
Authorized users work well when you want to give someone access to the card without making them legally responsible. Common situations include adding a spouse or adult child to manage household expenses, or adding a teenager to teach them how to use credit responsibly.
The authorized user does not need to have good credit, a job, or income. The card company does not run a credit check on them. This makes it a practical option if the person you want to add would not may have access to for their own card. However, the primary cardholder's credit score and income are what matter for approval — adding an authorized user does not strengthen your process if you would not may have access to on your own.
One important detail: if the authorized user runs up charges and you cannot pay, the issuer will pursue you, not them. The authorized user has no legal obligation to reimburse you. This is why authorized user arrangements work best when there is trust and a clear understanding about who pays for what.
When joint accounts make sense
A joint account makes sense when two people want to share both the benefits and the responsibility. If you are married or in a long-term partnership and manage finances together, a joint account can simplify billing and may support both people build credit history on the same account.
Joint accounts also matter if one person has poor or limited credit history and needs the other person's creditworthiness to be approved. In this case, both people's credit scores and income are considered during approval, and both are equally responsible for the debt. If the account is reported to credit bureaus, both people's credit reports will show the account and be affected by how it is managed.
The trade-off is legal exposure. If one joint holder stops paying, the issuer can pursue the other for the full balance. This is why joint accounts require a higher level of trust and financial alignment than authorized user arrangements.
How to add someone to your credit card account
The process varies by issuer, but the general steps are the same. Log into your online account or call the customer service number on the back of your card. Look for an option to add an authorized user or, if you are opening a new account, ask whether you can open it as a joint account during the process process.
For an authorized user, you will typically provide their full name, date of birth, and sometimes their Social Security number (though some issuers do not require it). The issuer will send a card in their name, or you can request a card without their name on it. The authorized user can start using the card when ready once it arrives.
For a joint account, the process is more involved because both people are signing a legal agreement. If you are converting an existing account to joint, the issuer may require the second person to sign paperwork. If you are opening a new joint account, both people typically need to explore together, and the issuer will review both credit profiles and income.
Some issuers allow you to set spending limits on authorized users, which can be useful if you want to control how much they can charge. Check your issuer's website or call to see whether this feature is available on your card.
Credit score impact for both parties
If the authorized user's name is reported to the credit bureaus, the account will appear on their credit report. This means the account history — including payment history, credit utilization, and age of account — will affect their credit score. If the account is paid on time and the balance stays low, their score can improve. If the account falls behind, their score can drop significantly, even though they are not legally responsible for paying.
The primary cardholder's credit score is always affected by the account, regardless of whether an authorized user is added. The joint holder's score is also always affected. The key difference is that an authorized user's credit can be damaged by an account they do not control, which is why this arrangement requires trust.
If you remove an authorized user, the account will eventually fall off their credit report (typically after seven years), but the impact on their score is when ready — their available credit decreases and their credit mix may change.
Alternatives if the card company says no
If the issuer does not offer joint accounts or authorized users, or if you want a different structure, you have other options. You can explore for a separate card together as co-applicants, though this is rare and most issuers treat each process independently. You can also become an authorized user on someone else's card, which gives you access without legal responsibility.
Another route is a secured credit card, which requires a cash deposit and is easier to may have access to for if your credit is limited. Both people can have their own secured cards and build credit independently.
If the goal is to help someone build credit, adding them as an authorized user on your well-managed card is usually the fastest and simplest path, even if it is not a formal cosigner arrangement.
Frequently Asked Questions
Does adding an authorized user help them build credit?
Yes, if the card issuer reports the account to the credit bureaus and the account is managed well. The authorized user's credit report will show the account, and on-time payments and low balances will help their score. However, late payments or high balances will also hurt their score, even though they are not legally responsible for paying.
Can I remove an authorized user without their permission?
Yes. As the primary cardholder, you can remove an authorized user at any time by contacting the card issuer. The authorized user does not have to agree. Once removed, the account will no longer appear on their credit report, though it may take a billing cycle or two to update.
What happens if a joint account holder does not pay?
The issuer can pursue either joint holder for the full balance. If one person does not pay and the account goes to collections, both people's credit scores are damaged. The issuer may sue either person or both. This is why joint accounts require clear agreements about who pays what.
Can I convert an authorized user to a joint account holder?
Some issuers allow this, but it typically requires paperwork and approval from both people. Contact your card company to ask whether conversion is possible and what steps are involved. The second person may need to sign a new agreement.
Do I need good credit to be an authorized user?
No. The card company does not check the authorized user's credit score or income. Only the primary cardholder's creditworthiness matters for approval. This makes authorized user status a practical option for people with no credit history or poor credit.
