About Routing Number 273970941 — CORNERSTONE BANK

Routing number 273970941 is the official 9-digit ABA routing number registered to CORNERSTONE BANK at 123 EAST MAIN STREET, CLARINDA, IA 51632. 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 273970941

The 9-digit number 273970941 is structured in three segments: 2739 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 CORNERSTONE BANK's transactions. 7094 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to CORNERSTONE 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.
