An authorized user is someone you add to your American Express account who can make purchases using a card linked to your account. You're the primary cardholder—the person legally responsible for all charges—while the authorized user simply has permission to spend on that account.
Think of it like giving a trusted person (often a family member or business associate) access to your account without transferring ownership or responsibility. You set the rules, you pay the bill, and you control whether the arrangement continues.
When you add an authorized user to your Amex card, the company typically issues them a physical card in their name, though they may also be able to make purchases through your account online or over the phone depending on how you set it up.
Key responsibility structure:
American Express may—but does not always—report the authorized user's activity to credit bureaus. This varies by card product and circumstance.
Family and household: Parents often add teenage children or spouses to manage shared expenses while teaching financial responsibility.
Business use: Sole proprietors or small business owners add employees, contractors, or partners who need access to company spending.
Credit building: Some people strategically add authorized users to help them establish or improve credit history, since authorized user accounts may appear on credit reports. However, this benefit is not guaranteed and depends on the card issuer's policies.
Convenience: Partners or family members may need regular access to funds for household or joint purchases.
| Authorized Users Can | Authorized Users Cannot |
|---|---|
| Make purchases up to any limits you set | Change account terms or credit limits |
| Use the card in-store, online, or by phone | Close the account or remove other users |
| Access some account information (varies) | Authorize additional users themselves |
| Benefit from card rewards (typically) | Dispute charges or manage billing details |
The exact permissions depend on your card type and what American Express allows you to configure.
Whether an authorized user arrangement affects credit depends on several factors:
Potential credit reporting: If American Express reports the authorized user account to credit bureaus, it may appear on the authorized user's credit report. If it does, the account history—including payment behavior and credit utilization—could influence their credit score. However, this is not guaranteed, and policies vary by card and issuer.
Primary cardholder's credit: Your own credit is unaffected by adding an authorized user. The account remains tied to your credit profile.
Risk consideration: If the authorized user runs up large balances, it increases your credit utilization ratio (the percentage of available credit you're using), which could impact your credit score, not theirs—unless they're also being reported.
You can remove an authorized user at any time, for any reason. Common situations include:
Removal is typically immediate. The card stops working, though the account history may remain visible depending on how you've set permissions.
The decision to add an authorized user—and how beneficial it is—depends on:
There's no one-size-fit-all answer. The right choice depends entirely on your circumstances, risk tolerance, and what you're trying to accomplish.
