The quickest way is to log in to First U.S. Online or Mobile Banking. Select the account you want, and your full account number will be listed under account details. You can also find it printed at the bottom of a check (it’s the second set of numbers, after the routing number), or on a recent paper or eStatement. If you can’t access any of these, First U.S. member service can look it up for you by clicking on the Chat Live bubble in the bottom right of your screen or just call (800) 556-6768.

You are about to leave the First U.S. website and go to a third-party site.
