How to Read Routing Number 103102106
The 9-digit number 103102106 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 BANK & TRUST CO's transactions. 0210 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to FIRST BANK & TRUST CO. 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.
