How to Read Routing Number 321177780

The 9-digit number 321177780 is structured in three segments: 3211 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 UNCLE CREDIT UNION's transactions. 7778 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to UNCLE CREDIT UNION. 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.
