External accounts generally refer to checking and savings accounts that you may have at financial institutions other than Washington Mutual Bank or Washington Mutual Bank fsb.
In some cases, we may treat Washington Mutual accounts as external accounts, such as when your account records are on a different processing and servicing system.
Depending on the terms of your external accounts, you may be able to designate one or more external accounts for transfers to your WaMu online accounts using the Washington Mutual online banking service.
