Yes. You can add authorized users online after you sign in, or you can call the number on the back of your card. Please note that to add an authorized user to your account, you must be the primary cardholder, secondary cardholder, power of attorney, or small business account manager. Adding a user can be done only if you’ve already been approved—not during the application process. We do not offer the option for co-applicants at this time, but you may add an authorized user after your account is opened.
