How to Read Routing Number 073920735
The 9-digit number 073920735 is structured in three segments: 0739 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 WASHINGTON ST BK's transactions. 2073 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to WASHINGTON ST BK. 5 is the check digit — a single digit calculated from the first eight digits using a weighted sum formula (3-7-1 multipliers).
