About Routing Number 121032232 — EAST WEST BANK

Routing number 121032232 is the official 9-digit ABA routing number registered to EAST WEST BANK at 9300 FLAIR DRIVE 4TH FLOOR, EL MONTE, CA 91731. It is registered with the American Bankers Association and the Federal Reserve E-Payments Routing Directory. This number is used exclusively within the US domestic payment system — for ACH transfers, direct deposits, check processing, and domestic wire transfers routed through Fedwire. It cannot be used for international transfers, which require a SWIFT/BIC code.

How to Read Routing Number 121032232

The 9-digit number 121032232 is structured in three segments: 1210 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 EAST WEST BANK's transactions. 3223 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to EAST WEST BANK. 2 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.
