What Credit Card Authority Means
Credit card authority is permission you give someone else to use your card or account. It does not mean they own the card or the debt — you remain responsible for every charge, whether you made it or someone else did. The person using the card is called an authorized user, and the rules about what they can do depend on how you set up the arrangement and which card issuer you use.
This matters because adding someone to your account changes your liability. If an authorized user runs up charges you cannot pay, the debt is yours to handle. If they commit fraud or use the card without permission, you still owe the money — though you may be able to dispute individual charges if you can prove you did not authorize them.
Key Takeaways
- An authorized user can use your card, but you remain legally responsible for all charges, even if you did not make them.
- Adding an authorized user does not split the debt or create a separate account — it is one bill in your name.
- You can set spending limits, restrict where the card works, or remove authorization at any time, depending on your card issuer.
- Authorized user activity typically shows up on your credit report and affects your credit score, so choose carefully who you add.
- If an authorized user charges more than you can pay, the debt collector will contact you, not them, because the account is yours.
How Authorized User Status Works
When you add an authorized user, you are giving them a card linked to your account. They are not a co-signer — a co-signer is someone who signs a loan with you and shares legal responsibility from the start. An authorized user has no legal obligation to pay anything. The card issuer looks to you for payment, period.
Most card issuers will report the authorized user's activity to the credit bureaus under your account. That means their charges count toward your credit utilization ratio (how much of your credit limit you are using), and late payments or high balances hurt your credit score, not theirs. Some issuers let you request that the account not be reported in the authorized user's name, but this varies by card and issuer.
You can usually set restrictions on what an authorized user can do. Some cards let you set a spending cap per transaction or per month. Others let you block certain types of purchases — online, international, or cash advances. You can also restrict which merchants the card works at. Call your card issuer to ask what controls are available on your specific card.
When You Are Liable for Authorized User Charges
You are liable for all charges an authorized user makes, with one narrow exception: if you report the card stolen or lost before the charges happen, your liability for unauthorized charges is capped at $50 under federal law (the Truth in Lending Act). Once you report the card missing, the issuer must stop honoring it.
If an authorized user makes charges after you have revoked their authority but before they return the card, you are still liable. The issuer does not know the authorization was revoked unless you tell them. Call your card issuer when ready and ask them to cancel the card number and issue you a new one. Do this in writing as well, so you have a record of when you revoked the authorization.
If an authorized user makes charges and then you dispute them as unauthorized, the burden is on you to prove you did not permit them. Text messages, emails, or written agreements saying you gave permission will work against you. If you genuinely did not authorize the charges, you will need to show the issuer evidence that the person used the card without your consent — for example, a police report for theft or fraud.
Adding an Authorized User to Build Credit
Some people add a family member as an authorized user hoping to help them build credit. This can work if the account has a low balance, a long history of on-time payments, and a high credit limit. The authorized user's credit score may improve because the account shows up on their credit report as an account in good standing.
However, this strategy has real risks. If you miss a payment or carry a high balance, the authorized user's credit score drops too — even though they did not make the charges. If the authorized user runs up the balance, your credit score suffers, and you owe the money. Some card issuers have also tightened rules around authorized users and no longer report them to credit bureaus, so the benefit may not happen at all.
Before adding someone as an authorized user for credit-building purposes, call your card issuer and confirm that the account will be reported in their name and that it will help their credit score. Ask whether there are any restrictions on how long the person needs to be on the account or what happens if they are removed.
Removing an Authorized User
You can remove an authorized user at any time by calling your card issuer. You do not need their permission or agreement. Tell the issuer you want to revoke the authorization and ask them to cancel the card they were issued.
Once you remove someone, they can no longer use the card. However, the account history may remain on their credit report for a period of time — usually seven to ten years for positive accounts, or longer if there were late payments. Removing an authorized user does not erase the history of charges they made or the account's payment record.
If you are removing an authorized user because they have been using the card without your permission or against your wishes, also consider whether you need to report the card as lost or stolen to prevent further charges. If the person refuses to return the card, you may need to file a police report for theft.
The Difference Between Authorized Users and Co-Signers
A co-signer signs a loan or credit process with you and agrees in writing to pay if you do not. They have legal responsibility from the beginning. A co-signer's credit is checked before they sign, and the debt appears on both of your credit reports as a shared obligation.
An authorized user has no legal obligation to pay. They are straightforward permitted to use the card. Their credit is not checked, and they do not sign anything. You can remove them without their consent, but you cannot remove a co-signer without their agreement or a court order.
If you are trying to help someone build credit, adding them as an authorized user is lower-stakes than making them a co-signer. If you are borrowing money and need someone to vouch for you, you will need a co-signer, not an authorized user.
What Happens If an Authorized User Does Not Pay
The card issuer will contact you for payment, not the authorized user. You are the account holder, and the debt is in your name. If you do not pay, the issuer may report the account as delinquent to the credit bureaus, sue you for the balance, or send the account to a debt collector.
You can try to recover the money from the authorized user through small claims court or by suing them directly, but that is your problem to solve, not the card issuer's. The issuer has no obligation to pursue the authorized user or split the debt between you.
If you and the authorized user have a written agreement that they will pay for certain charges, keep that agreement. It may help you recover money in court, but it does not change your legal responsibility to the card issuer.
Frequently Asked Questions
Can an authorized user see my credit score or account balance?
That depends on your card issuer and how you set up the account. Some issuers give authorized users access to the full account online, including the balance and payment history. Others restrict what they can see. Call your issuer and ask what information authorized users can view, or log into your account and check the settings.
What if I add someone as an authorized user and they run up a huge balance?
You owe it. The debt is yours. You can ask the authorized user to pay you back, but the card issuer will pursue you for the full amount if you do not pay. If you cannot afford the balance, you may need to negotiate a payment plan with the issuer or explore debt management options. Removing the authorized user stops new charges but does not erase what they already charged.
Does adding an authorized user hurt my credit score?
Not when ready. Adding an authorized user does not trigger a hard inquiry or lower your score on its own. However, if the authorized user charges a lot and increases your credit utilization ratio, your score may drop. If they miss payments, your score will drop significantly.
Can I add an authorized user without their knowledge?
Technically yes, but it is a bad idea. You can order a card in someone else's name and add them to your account without their permission. However, if they do not know about it, they cannot use it responsibly, and you are liable for any fraud or misuse. If you are thinking about doing this, tell the person first and get their agreement in writing.
What if an authorized user commits fraud with my card?
Report it to your card issuer when ready and ask them to cancel the card. If you can show the issuer that the person used the card without your permission, you may be able to dispute the charges. However, if you gave them the card or permission to use it, the issuer will likely hold you responsible. If the fraud is serious, consider filing a police report.
