About Routing Number 102104846 — MOUNTAIN VALLEY BANK

Routing number 102104846 is the official 9-digit ABA routing number registered to MOUNTAIN VALLEY BANK at PO BOX 279, HAYDEN, CO 81639-0758. 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 102104846

The 9-digit number 102104846 is structured in three segments: 1021 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 MOUNTAIN VALLEY BANK's transactions. 0484 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to MOUNTAIN VALLEY BANK. 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.
