FAQs

Common questions about ACH and wires through Associated Bank

Why does Associated Bank use only one routing number for the entire Midwest?

Associated Bank streamlines banking operations by using a single routing number (075900575) across all its locations in Wisconsin, Illinois, Minnesota, and other Midwest states. This approach simplifies the customer experience and reduces errors in payment processing. The bank was formed in 1970 through the consolidation of three Wisconsin banks, and over time they standardized operations under one routing number rather than maintaining separate numbers for each acquired institution or region.

Can I use the same routing number for both ACH and wire transfers at Associated Bank?

Yes, Associated Bank uses routing number 075900575 for all domestic transaction types, including ACH transfers, wire transfers, direct deposits, and bill payments. This makes it easier to remember and reduces confusion when setting up different types of payments. For international wire transfers, you'll also need to provide Associated Bank's SWIFT code (ABGBUS44) in addition to the routing number.

What is Associated Bank's SWIFT code for international transfers?

Associated Bank's SWIFT code is ABGBUS44. This code is required for receiving international wire transfers and ensures that funds from overseas are properly routed to your Associated Bank account. International wire transfers typically take 2-4 business days to process and may incur additional fees from intermediary banks involved in the transfer process.

How do I find my Associated Bank routing number on my check?

Your Associated Bank routing number appears as the first nine digits in the bottom-left corner of your checks. The routing number (075900575) is followed by your account number and then the check number. You can also find your routing number by logging into Associated Bank's online banking platform or mobile app under account details.

Does Associated Bank charge fees for wire transfers?

Yes, Associated Bank charges fees for wire transfers. For consumer accounts, domestic outgoing wire transfers cost $25 each, while incoming domestic wires cost $15. International outgoing wire transfers range from $45 to $85 depending on whether you choose BEN, OUR, or FULL SWIFT charge options. Incoming international wires cost $15. These fees can add up quickly for businesses making frequent payments, which is why many companies are switching to ACH transfers or services like Nickel for more cost-effective payment processing.
