A denial of service block is a single service block that blocks a person or organization from enrolling in a service (such as bill pay) or performing a service (such as an outgoing wire transfer). A transaction attribute fraud block list allows the credit union to enter a data element that is used to determine if an activity should be blocked for any member (such as the “pay to name” when disbursing funds or the country when performing an outgoing wire).
All fraud block lists are accessed from Tool #892 Update Fraud Alert/Blocked Persons List.
