A US Bank routing number, also known as an ABA routing number, is a nine-digit code that identifies the financial institution where an account is held. For instance, the routing number for US Bank in Minneapolis, MN is 091000024.
Routing numbers play a crucial role in the electronic transfer of funds, ensuring that payments reach the intended recipient’s account. They have been used in the US since the late 1960s, when the American Bankers Association (ABA) implemented the MICR (Magnetic Ink Character Recognition) system for automated check processing.
