Sign up for Express Cash
An American Express cardholder can sign up for the Express Cash program by contacting American Express customer service at 800-327-4669. When calling, the cardholder should have his account number and Social Security number ready to verify his account and identity. American Express does not allow enrollment in Express Cash online or through email.
Find an ATM
Currently, cash advances are only available at participating automated teller machines, which a cardholder can find through the ATM locator on the American Express website. He can withdraw cash in amounts up to his card's available cash advance limit, which varies depending on the card and the account holder. Each cardholder has a personal identification number he must enter at the ATM to receive the cash. The cash advance fee varies depending on the card. The Blue Cash Everyday card, for example, has a cash advance fee of $5 or 3 percent of the cash advance amount, whichever is greater.
