Welcome to Prosperity Bank

This weekend marks an important milestone as American Bank's systems, digital services, and website transition to Prosperity Bank.

Effective Monday, September 14, the American Bank website will be retired. Please visit www.prosperitybankusa.com for online banking, account information, and all other banking services.

American Bank Personal Online and Mobile Banking will no longer be accessible after 4 p.m. on September 11. On September 14, you will begin using Prosperity Bank's Business Online and Mobile Banking platforms.

Thank you for your continued trust and patience throughout this transition. We look forward to continuing to serve you as Prosperity Bank.

For immediate assistance, please contact Customer Service at (800) 531-1401.
