About Routing Number 275082646 — SUMMIT CREDIT UNION

Routing number 275082646 is the official 9-digit ABA routing number registered to SUMMIT CREDIT UNION at 4800 AMERICAN PKWY, MADISON, WI 53718. 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.

How to Read Routing Number 275082646

The 9-digit number 275082646 is structured in three segments: 2750 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 SUMMIT CREDIT UNION's transactions. 8264 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to SUMMIT CREDIT UNION. 6 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.
