We recognize that you may have questions or concerns during this transition and want to address two important points right away:

What should you do about charges automatically billed to your old card?

After you receive your new card, you must provide your new card number and expiration date to companies (like online service providers, newspapers, or the phone company) that automatically bill your card.

Will your rewards program benefits continue?

Absolutely! Your existing points will be retained with no loss in value, and you will continue to earn one point for every net dollar spent on purchases, just like before. Plus, starting April 1, 2013, you’ll enjoy expanded reward options including easier travel rewards and new, local reward choices.

We welcome you to contact credit card customer service at with any questions you may have.
