How to Read Routing Number 311372744

The 9-digit number 311372744 is structured in three segments: 3113 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 INTERSTATE BANK,SSB's transactions. 7274 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to INTERSTATE BANK,SSB. 4 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.
