About Routing Number 101902366 — BANK 21

Routing number 101902366 is the official 9-digit ABA routing number registered to BANK 21 at 1 WEST WASHINGTON AVE, CARROLLTON, MO 64633. It is registered with the American Bankers Association and the Federal Reserve E-Payments Routing Directory.

How to Read Routing Number 101902366

The 9-digit number 101902366 is structured in three segments: 1019 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 BANK 21's transactions. 0236 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to BANK 21. 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.
