Hm, how do you get visitors? You don't show up on the first page of Google results for 'bank of america routing number' for me. (I guess you show up second if I add certain state names.)
Can someone explain what this is, is it like a UK sort-code [which identifies a particular bank branch, like a zip-code only for banks]? Why do people need to look it up [online].
The ABA routing number is a 9-digit identification number assigned to financial institutions by The American Bankers Association (ABA). This number identifies the financial institution upon which a payment is drawn. Routing numbers are sometimes referred to as "check routing numbers", "ABA numbers", or "routing transit numbers" (RTN). Routing numbers may differ depending on where your account was opened and the type of transaction made.
