How to Read Routing Number 103105637

The 9-digit number 103105637 is structured in three segments: 1031 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 FIRST AMERICAN BK's transactions. 0563 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to FIRST AMERICAN BK. 7 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.
