About Routing Number 091408734 — GREAT WESTERN BANK

Routing number 091408734 is the official 9-digit ABA routing number registered to GREAT WESTERN BANK at 3405 N. LOUISE AVE, SIOUX FALLS, SD 57107. It is registered with the American Bankers Association and the Federal Reserve E-Payments Routing Directory.

How to Read Routing Number 091408734

The 9-digit number 091408734 is structured in three segments: 0914 is the Federal Reserve routing symbol — the first two digits identify the Federal Reserve district and the next two identify the specific Federal Reserve processing office handling GREAT WESTERN BANK's transactions. 0873 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to GREAT WESTERN BANK. 4 is the check digit — a single digit calculated from the first eight digits using a weighted sum formula (3-7-1 multipliers). Payment processing systems run this calculation in real time to catch routing number entry errors before any funds move.
