What are Chase Credit Card Free Alerts?
Free Alerts are notifications about your account sent by e-mail or phone. E-mail alerts in text format can be sent to your e-mail address, mobile phone, pager or PDA to keep you informed about your account.
If you select Phone alerts, we'll call you with the important account information you requested at the number you designate. Free Alerts can remind you when your payment is due, notify you when your balance reaches a set amount, and much more.
With Free Alerts, you're always in the know and you can choose the Alert preferences that are right for you. The service is free* and can be discontinued at any time. There are six credit card Alerts to choose from.
