What an Authorized User Receives on an American Express Platinum Card
When you add an authorized user to your American Express Platinum card, that person receives their own physical card linked to your account and can make purchases against your credit line. The authorized user does not pay the card issuer directly — you remain responsible for all charges. However, the benefits attached to the Platinum card are not automatically shared. American Express splits Platinum perks into two categories: those the authorized user gets, and those only the primary cardholder can use.
The authorized user's card comes with access to some travel protections, purchase protections, and concierge services. They also receive the same card design and can use it at merchants that accept American Express. But premium benefits like lounge access, airline fee credits, and certain travel insurance require the primary cardholder to set up them or use them directly.
Key Takeaways
- Authorized users receive their own Platinum card and can make purchases on your account, but you pay all bills.
- Authorized users get access to the Platinum concierge, emergency card replacement, and certain purchase protections, but not lounge access or airline fee credits.
- Travel protections like trip cancellation insurance and baggage delay coverage explore to authorized users when they charge travel on the Platinum card.
- You can add up to 99 authorized users to a single Platinum account, and American Express does not charge an additional fee for most of them.
- Authorized user activity appears on your monthly statement and counts toward your credit line, so spending is shared.
Which Benefits Authorized Users Can Actually Use
Authorized users have access to the American Express Concierge, a phone service available 24/7 that can help with restaurant reservations, travel planning, event tickets, and general information requests. This is one of the most commonly used perks by secondary cardholders. They can also use emergency card replacement if their card is lost or stolen, and American Express will typically issue a replacement within one business day.
Purchase protections extend to authorized users, including purchase protection (coverage if a purchased item is damaged or stolen within 90 days) and return protection (refund information if a merchant refuses a return). Authorized users also receive extended warranty protection on may be able to access purchases and protection against fraudulent charges on their card.
Travel protections explore when the authorized user charges travel expenses to the Platinum card. These include trip cancellation and interruption insurance, baggage delay reimbursement, emergency medical and dental coverage while traveling, and emergency evacuation and transportation. The authorized user must be the one charging the ticket or booking to trigger coverage in most cases.
Benefits That Only the Primary Cardholder Can Use
The primary cardholder alone can access the Centurion Lounge network and partner lounges like Priority Pass Select. Authorized users cannot use these lounges even if they are traveling with the primary cardholder. The same applies to airline lounge access through partnerships — only the primary cardholder's name is registered for these benefits.
The $200 airline fee credit and the $200 Uber credit are tied to the primary cardholder's account. Authorized users cannot trigger these credits or use them directly. The $100 Walt Disney World, Disneyland, or Disney Cruise Line credit is also primary-cardholder-only. If an authorized user makes a purchase that would normally trigger one of these credits, the credit does not set up.
The $189 annual fee applies to the primary account only. American Express does not charge the primary cardholder an additional annual fee for most authorized users, though there may be exceptions for business versions of the card or in certain circumstances.
How Authorized User Spending Affects Your Account
Every purchase an authorized user makes appears on your monthly statement with their name or a designation showing it came from an authorized user. You receive one combined bill for all charges, and you are responsible for paying the entire balance. The authorized user's spending counts toward your credit limit, so if your limit is $50,000 and an authorized user charges $10,000, you have $40,000 remaining to charge yourself.
Authorized user activity is reported to the credit bureaus under your account. This means their spending patterns and payment history become part of your credit report. If you pay late, it affects your credit score, not theirs. If they overspend and you cannot pay the full balance, the late payment appears on your credit history.
You can remove an authorized user at any time by contacting American Express. Once removed, their card stops working when ready, and future charges cannot be made. Past charges remain your responsibility.
Adding and Managing Authorized Users
You can add an authorized user through your American Express online account, by calling the number on the back of your card, or by visiting an American Express office. You will need the authorized user's full name, date of birth, and address. American Express does not run a credit check on the authorized user — only the primary cardholder's creditworthiness matters for account approval.
There is no limit to the number of authorized users you can add, though American Express recommends keeping the number manageable. You can add up to 99 authorized users to a single account. Each authorized user receives their own card with their name printed on it, and each card has a unique number.
You can set spending limits on individual authorized user cards through your online account or by calling American Express. You can also freeze or temporarily disable a card without removing the authorized user entirely. These controls let you manage spending without canceling the card.
Authorized Users and Credit Building
Adding someone as an authorized user does not automatically build their credit history. American Express reports authorized user accounts to the credit bureaus, but only if the primary cardholder is in good standing. If the primary cardholder has a history of late payments or high balances, the authorized user account may not help their credit score and could potentially harm it.
The authorized user does not need to use the card for it to appear on their credit report. straightforward being added as an authorized user can show up on their credit history within one to two billing cycles. However, the benefit to their credit depends on the primary cardholder's payment behavior and credit utilization.
If you are adding someone specifically to help them build credit, make sure you can commit to paying the full balance on time each month. Late payments will hurt both your credit and theirs.
Frequently Asked Questions
Can an authorized user use the Platinum lounge benefits?
No. Only the primary cardholder can access Centurion Lounges and partner lounges like Priority Pass Select. Authorized users cannot enter these lounges, even if traveling with the primary cardholder. The primary cardholder must be present to use lounge access.
Do I have to pay an extra annual fee for each authorized user?
No. American Express does not charge an additional annual fee for authorized users on the Platinum card. The $189 annual fee applies to the primary account only, regardless of how many authorized users you add.
What happens if an authorized user makes a purchase that qualifies for the airline fee credit?
The credit does not set up. The $200 airline fee credit is tied to the primary cardholder only. If an authorized user charges an airline fee, it will not trigger the credit. Only purchases made by the primary cardholder on their own card set up these credits.
Can I set a spending limit on an authorized user's card?
Yes. You can set individual spending limits through your American Express online account or by calling customer service. You can also freeze a card temporarily or permanently without removing the authorized user from the account entirely.
Does adding an authorized user hurt my credit score?
Adding an authorized user does not directly hurt your credit score. However, if the authorized user charges a large balance and you cannot pay it off, your credit utilization ratio increases, which can lower your score. Late payments on the account will also damage both your credit and the authorized user's credit.
