About Routing Number 281081246 — MEMBERS 1ST CREDIT UNION

Routing number 281081246 is the official 9-digit ABA routing number registered to MEMBERS 1ST CREDIT UNION at 4702 MATTIS ROAD, ST LOUIS, MO 63128-2822. 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 281081246

The 9-digit number 281081246 is structured in three segments: 2810 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 MEMBERS 1ST CREDIT UNION's transactions. 8124 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to MEMBERS 1ST CREDIT UNION. 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.
