Routing number 102305098 is the official 9-digit ABA routing number registered to ROCKY MOUNTAIN BANK at P.O BOX 938, JACKSON, WY 83001. It is registered with the American Bankers Association and the Federal Reserve E-Payments Routing Directory.

How to Read Routing Number 102305098
The 9-digit number 102305098 is structured in three segments: 1023 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 ROCKY MOUNTAIN BANK's transactions. 0509 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to ROCKY MOUNTAIN BANK. 8 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.
