About Routing Number 122244236 — COMMERCEWEST BANK NA

Routing number 122244236 is the official 9-digit ABA routing number registered to COMMERCEWEST BANK NA at 2111 BUSINESS CENTER DRIVE, IRVINE, CA 92612. It is registered with the American Bankers Association and the Federal Reserve E-Payments Routing Directory.

How to Read Routing Number 122244236

The 9-digit number 122244236 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 COMMERCEWEST BANK NA's transactions. 4423 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to COMMERCEWEST BANK NA. 6 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.
