How to Read Routing Number 324172588

The 9-digit number 324172588 is structured in three segments: 3241 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 E S A CREDIT UNION's transactions. 7258 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to E S A CREDIT UNION. 8 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.
