Marion Bank Routing Numbers

Marion is home to 1 banks and credit unions, each with their own ABA routing number used for identifying the institution during domestic transactions. Whether you're setting up direct deposit, scheduling a bill payment, or initiating a wire transfer, you'll need the correct routing number for your specific branch in Marion.

Routing numbers in Marion follow the standard 9-digit ABA format established by the American Bankers Association. The first two digits indicate the Federal Reserve district, digits 3-4 identify the processing center, digits 5-8 are the institution identifier, and the final digit is a checksum. Large national banks like Chase, Bank of America, and Wells Fargo often have different routing numbers for each state, so always verify you're using the South Dakota-specific number.

For ACH transfers (direct deposits, payroll, bill pay), processing typically takes 1-2 business days through the Federal Reserve. Wire transfers using Fedwire settle same-day but may require a different routing number at some institutions — always confirm with your bank before sending a wire.
