Amex Business Platinum Authorized User: A Complete Guide

There are significant differences between a cardholder and an authorized user. The cardholder is a decision-maker. The authorized user is granted certain privileges, but they don’t have full administrative authority over the credit card account. While that’s a simple distinction, the agreement's terminology, fees, and benefits may require some explanation.

This guide breaks down how the structure works, what it costs, and how using a Wise Business account can stretch every dollar further when spending internationally.

What Are Amex Business Platinum Authorized Users? The Basics

An authorized user on an Amex Business Platinum card is someone you add to your account so they can transact under your credit line. The user receives a card in their name, but the primary account holder remains fully liable for all charges made.¹ Core benefits that extend to the authorized user include:

• Access to the American Express Global Lounge Collection, which covers over 1,550 airport lounges worldwide²
• Eligibility for a $120 Global Entry or up to $85 TSA PreCheck application fee credit every four years²
• Complimentary hotel elite status at Hilton Honors and Marriott Bonvoy properties
• Rental car elite status with partners, including Avis, Hertz, and National
• Purchase protection and select travel insurance benefits

The Amex Business Platinum authorized user fee currently sits at $400 per year for each employee's Business Platinum Card.³

Amex Business Platinum "Employee Card" vs. "Authorized User"

This is where customers often get confused. American Express refers to Platinum Card authorized users as “additional card members.” That suggests equality, not the hierarchy that more accurately describes the situation. On the authorized user side, American Express uses the term "Additional Business Platinum Card," also commonly called an "Employee Card."⁴

This is where we can offer at least some clarity. The Amex Business Platinum Card offers two distinct options for adding people, and each has its own fee structure:

• Employee Business Platinum Card: $400 annual fee, with full extended benefits like lounge access and travel credits. You can add up to five of these cards.³
• Employee Business Expense Card: No annual fee, with no extended benefits. Purchases still earn Membership Rewards points on your main account, and you can add up to 99 of these cards.

The distinction matters for business financial planning. The expense card comes with no fee, making it an ideal choice for an employee who only needs a corporate purchasing card for everyday expenses. The Employee Business Platinum Card is a good choice for employees who travel frequently and need access to airport lounges and rental cars.

How to Add an Authorized User to Your Amex Business Platinum Card

Adding an authorized user to the Amex Business Platinum card takes about 5 minutes when done online. Here is the step-by-step workflow:

1. Log in to your American Express business account at americanexpress.com
2. Navigate to "Account Services" and select "Add Someone to Your Account."
3. Choose the card type — Employee Business Platinum Card or Employee Business Expense Card
4. Enter the authorized user's full name, date of birth, and Social Security Number (SSN). The user must be at least 13 years old.⁶
5. Set optional spending limits or card controls for the new user
6. Review and accept the applicable annual fee
7. Submit the request and wait for the card to ship

American Express typically ships the new card within 7 to 10 business days. The authorized user then activates it online or by phone.

What Are the Key Benefits for Amex Business Platinum Authorized Users?

The Amex Business Platinum authorized user benefits mirror much of what primary cardholders enjoy, and there are a few strategic use cases for small and mid-sized businesses:

• Travel perks: Each user gets full access to the Global Lounge Collection, including Centurion Lounges, Delta Sky Clubs (up to 10 same-day Delta visits annually), Priority Pass Select, Plaza Premium, and other partner networks.
• Team travel management: Assigning premium cards to employees who travel gives them independent lounge access and streamlined booking tools.
• Segmented spending: Using different authorized user cards for different departments, projects, or vendor categories simplifies expense reconciliation.
• Rewards acceleration: All spending on authorized user cards earns Membership Rewards points on your main account.
• International business spending: Employees traveling abroad get the same lounge access and no-foreign-transaction-fee benefit as the primary cardholder.⁷

The Costs and Considerations: Beyond the Annual Fee

The true cost of an Amex Business Platinum authorized user goes beyond the headline $400 fee. Weigh these factors before adding cards:

• Primary account holder liability: You are 100% responsible for every charge. If an employee disputes a purchase or overspends, the balance still comes back to you.
• Spending limits and controls: The Business Platinum lets you set per-card spending caps and instantly freeze cards, helping manage risk across a team.
• Credit and reporting: Because this is a business charge card, authorized user activity does not appear on the user's personal credit report. It’s tied to your business credit profile.
• Terms and conditions change: Amex raised the Additional Business Platinum Card fee from $350 to $400 for accounts opened on or after September 18, 2025. This update affects new and renewing cardholders differently.

Maximizing Value: The Wise Advantage for International Business Spending

The US Business Platinum does not charge a foreign transaction fee, which looks like a win for international travelers.⁷ However, AMEX converts foreign charges using its own exchange rate, published by AE Exposure Management Ltd. (AEEML), which may differ from the mid-market rate you see on Google.⁸

Here is a simple example. If an authorized user spends $5,000 abroad over the course of a year, even a modest 1% spread between the Amex conversion rate and the mid-market rate costs you around $50. Scale that across a five-person team, and the leak becomes meaningful.

Common Questions About Amex Authorised Users

What is the real difference between an "employee card" and an "authorized user" on the Amex Business Platinum?

American Express uses these terms interchangeably when describing its “additional card member” options. With its Business Platinum card, Amex offers two “employee” cards. The Employee Business Platinum Card costs $400 per year and comes with full benefits. The Employee Business Expense Card has no fee and comes with no benefits.

Is adding an Amex Business Platinum authorized user worth the annual fee?

The fee is worth paying if the card is being issued to an employee who travels frequently. A good example of this is an employee who uses the Global Lounge Collection, the Global Entry credit, and elite status rental cars. Those services more than offset the $400 annual fee. The Employee Business Expense Card can be a better option for those who don’t incur these expenses.

Conclusion: Should Your Business Add Amex Business Platinum Authorized Users?

The Amex Business Platinum's authorized-user structure offers two solid options for employee expenses. Understanding the differences between them is the first step toward optimizing cost and control.

Pair that with Wise Business for international payments, and your company keeps premium benefits without paying a premium on every currency conversion.
