It is registered with the American Bankers Association and the Federal Reserve E-Payments Routing Directory.

How to Read Routing Number 122239843
The 9-digit number 122239843 is structured in three segments: 1222 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 PACIFIC WESTERN BANK's transactions. 3984 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to PACIFIC WESTERN BANK. 3 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.
