If a person or organization is added to the outgoing wire denial of service block list, an employee cannot send an outgoing wire for any membership with that SSN/TIN.  If the employee tries to send an outgoing wire via Tool #73 Post Wire Transfer to Member Account, and select Outgoing,” they will see messaging that the “SSN/TIN appears on block list.”
You may consider also adding the member to the incoming wire fraud block list.

If a match is found on a block list, follow your credit union policies and procedures.  (In order to remove the block, you will need to remove the membership from the appropriate block list.)

All fraud block lists are accessed from Tool #892 Update Fraud Alert/Blocked Persons List.
