For more than 123 years, Great Southern Bank has been a part of East Central Mississippi, and we have considered it a privilege to serve you.  Our vision statement is very clear - “To be a trusted financial partner, empowering individuals, businesses, and our communities to achieve long-term financial well-being”.  In everything we do, we strive to follow this statement in serving you.  With that in mind, we would like to make you aware of an upgrade we will make very soon. 

On March 6, 2026, we will migrate our core software system to a new and improved system.  This is a major upgrade to our software that will affect our normal bank operations during the weekend of March 5-9.  While we prefer not to interrupt your routine, this upgrade is necessary as we seek ways to enhance our service to you.

We appreciate you and your patience during the migration weekend.  If you have any questions or concerns or simply want to talk to us about the migration process or the changes to your product or service, please reach out to your GSB banker.  We are here for you before, during and after this process.  Thank you for choosing Great Southern as your financial partner.  We look forward to serving you for many years to come.
