Routing number 243083198 is the official 9-digit ABA routing number registered to ALCOA CREDIT UNION at 30 ISABELLA ST, PITTSBURGH, PA 15212. 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 243083198
The 9-digit number 243083198 is structured in three segments: 2430 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 ALCOA CREDIT UNION's transactions. 8319 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to ALCOA CREDIT UNION. 8 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.
