About Routing Number 042106331 — COMMERCIAL BANK
Routing number 042106331 is the official 9-digit ABA routing number registered to COMMERCIAL BANK at 151 UNIVERSITY DR., WEST LIBERTY, KY 41472. 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 042106331
The 9-digit number 042106331 is structured in three segments: 0421 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 COMMERCIAL BANK's transactions. 0633 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to COMMERCIAL BANK. 1 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.
