Routing number 043312386 is the official 9-digit ABA routing number registered to MARS BANK at 145 GRAND AVENUE, MARS, PA 16046-0927. 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.

How to Read Routing Number 043312386
The 9-digit number 043312386 is structured in three segments: 0433 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 MARS BANK's transactions. 1238 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to MARS 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.
