About Routing Number 321174149 — ALLIANT CREDIT UNION

Routing number 321174149 is the official 9-digit ABA routing number registered to ALLIANT CREDIT UNION at 11545 W TOUHY AVENUE, CHICAGO, IL 60666. It is registered with the American Bankers Association and the Federal Reserve E-Payments Routing Directory. This number is used exclusively within the US domestic payment system — for ACH transfers, direct deposits, check processing, and domestic wire transfers routed through Fedwire. It cannot be used for international transfers, which require a SWIFT/BIC code.

How to Read Routing Number 321174149

The 9-digit number 321174149 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 ALLIANT CREDIT UNION's transactions. 7414 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to ALLIANT CREDIT UNION. 9 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.
