Overview: Fraud Block Lists

Block Lists create a centralized place to see and stop activity based on patterns the credit union sees as risky or potentially fraudulent. In addition, by using an infrastructure independent from membership and other key data tables, Block Lists give us maximum flexibility to add and alter block list options, without a large ripple effect when we expand the lists.
