How to Read Routing Number 121181743

The 9-digit number 121181743 is structured in three segments: 1211 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 PACIFIC SERVICE CREDIT UNION's transactions. 8174 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to PACIFIC SERVICE CREDIT UNION. 3 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.
