How to Read Routing Number 073901880

The 9-digit number 073901880 is structured in three segments: 0739 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 IA ST BK & TR CO's transactions. 0188 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to IA ST BK & TR CO. 0 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.
