A routing number, also known as an American Bankers Association (ABA) number, is a nine-digit code that identifies the financial institution where an account is held. The Great Western Bank routing number is 122205229. This number is used to facilitate electronic fund transfers (EFTs) and other banking transactions.
Routing numbers are essential for processing checks, direct deposits, and wire transfers. They ensure that funds are sent to the correct financial institution and account. Routing numbers have been in use since the early 1900s, and they have played a crucial role in the development of the modern banking system.
