Routing number 121142834 is the official 9-digit ABA routing number registered to BANNER BANK at 110 S FERRALL STREET, SPOKANE, WA 99202. It is registered with the American Bankers Association and the Federal Reserve E-Payments Routing Directory.

How to Read Routing Number 121142834

The 9-digit number 121142834 is structured in three segments: 1211 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 BANNER BANK's transactions. 4283 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to BANNER 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.
