How do I check the balance on my American Express Serve prepaid card?

To check the balance on an American Express Serve prepaid card, one can easily do so by logging in to their online Serve account through the official website or by using the Serve mobile app. Once logged in, the dashboard typically displays the available balance prominently. Additionally, cardholders may check their balance over the phone by calling the number on the back of their card and following the automated prompts or speaking with a customer service representative. For convenience, users can also register for text alerts to receive balance updates directly to their phone.
