One American Bank Routing Number

What is an ABA routing number?

An ABA routing number, also called a routing transit number (RTN), is a 9-digit code that identifies a U.S. financial institution in the payment system.

The format was created by the American Bankers Association in 1910 and is still the backbone of U.S. domestic payments.
