NOTICE: We apologize, but we are currently experiencing high call volume. If you try to call us, you may experience a greater hold time than usual. If you are accessing online or mobile banking, you may experience slowness due to the high volume.

Some of your former Landmark Bank products and services will be transitioning to Simmons Bank throughout the remainder of 2020. We will keep you informed about those transition dates and let you know if there's any action you need to take. For now, we've listed all of your former Landmark Bank logins on this page for easy access.

For any questions or concerns, please contact Simmons Bank at 1-866-246-2400 or email
