Add Supplementary Cards to your Account to share the world of American Express with those dear to you.

Share access to the benefits you love

A Supplementary Card is an additional Card that lets you share the benefits and convenience of your American Express® Card with family or friends. With just one account, Supplementary Cards can be used in different locations at the same time. Plus, you will earn points, miles or cashback whenever additional Card Members use their Supplementary Card.

Earn rewards faster 

Earn rewards on your Supplementary Card Member's purchases the same way you do on your own Card, so rewards can really add up.
