How do I add someone to my AmEx Platinum card as an authorized user?

To add someone as an authorized user to your American Express Platinum Card, you must be the primary cardholder. Log in to your American Express account online or open the American Express mobile app. Navigate to the 'Account Management' section and find the option for adding an authorized user; you may be prompted either directly on your dashboard or under 'Card Management' settings. Enter the required personal details of the individual you want to add, which typically include their full name, date of birth, and Social Security Number. It is important to ensure that the person being added as an authorized user is aware and consents to this action since they will have charging privileges on your account. Once you have submitted the necessary information, American Express will process the request and, upon approval, will issue a card to the authorized user with their name on it. They enforce certain terms, conditions, and potential fees for adding authorized users, so review those beforehand to understand all implications thoroughly.
