How to Read Routing Number 274074105

The 9-digit number 274074105 is structured in three segments: 2740 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 INDIANAPOLIS POST OFFICE CR UN's transactions. 7410 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to INDIANAPOLIS POST OFFICE CR UN. 5 is the check digit — a single digit calculated from the first eight digits using a weighted sum formula (3-7-1 multipliers).
