How to Read Routing Number 081017342

The 9-digit number 081017342 is structured in three segments: 0810 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 SIMMONS FIRST NATL BK's transactions. 1734 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to SIMMONS FIRST NATL BK. 2 is the check digit — a single digit calculated from the first eight digits using a weighted sum formula (3-7-1 multipliers).
