What is an ABA number (or routing number)?
Your ABA number is a 9-digit number assigned to the bank by the American Bankers Association (ABA). It's used for routing transfers and other transactions. Think of it as the bank's "address". It's also often called the routing number. You'll need to provide an ABA number if you reorder checks, set up a direct deposit or automatic payment, or send a wire transfer (domestic only).
The ABA or routing number is usually located at the lower left corner of a check. If you do not have your checkbook handy but you have written a check in the last 18 months, then you can see the check image on your Account Details page by selecting "view image".
