Associated Bank’s routing number is 075900575. Associated Bank currently says it uses this same routing number across its banks in Illinois, Minnesota, and Wisconsin. If you’re setting up direct deposit, an ACH payment, or another routine bank transfer, that is the number to verify against your account information.
One caution matters more than memorizing the nine digits: do not assume the routing number on a check is automatically the complete instruction set for every wire transfer. Domestic and especially international wires can require separate bank instructions, beneficiary details, or intermediary-bank information. For a wire, confirm the current instructions with Associated Bank before you send the money.
Quick Answer
Associated Bank’s routing number is 075900575. The bank says it uses that number across its Illinois, Minnesota, and Wisconsin locations. You can verify it on an Associated Bank check, through Associated Bank Digital, on a bank statement, or directly with the bank. If the transaction is a wire, verify the bank’s current wire instructions instead of relying only on the routing number printed on a check.

What Is Associated Bank’s Routing Number Used For?
A routing number is the nine-digit ABA identifier used to identify a U.S. financial institution during transactions. Your routing number identifies the bank; your account number identifies your specific checking or savings account.
Associated Bank’s official routing-number page lists 075900575. The bank’s own routing-number guide says the number is used across its Illinois, Minnesota, and Wisconsin banks and recommends verifying the number for your specific situation.
Routing number vs. account number
Think of the routing number as identifying the bank and the account number as identifying your specific account at that bank. On a personal check, the routing number is normally the first nine-digit number at the bottom left.

How to Find and Verify Your Associated Bank Routing Number
When clients asked me how to find a routing number, I pointed them back to official bank sources. That is still the safest habit here. Associated Bank itself lists several ways to find or confirm your number.
1. Check the Bottom Left of a Personal Check
Associated Bank says the routing number is the first series of numbers at the bottom left of its checks. Your account number appears to the right. For Associated Bank, the routing number shown by the bank is 075900575.
2. Check Associated Bank Digital
Associated Bank’s routing-number guide says you can find the routing number through the bank’s online portal or mobile app. Use the account information shown inside your authenticated Associated Bank Digital session rather than relying on a number copied from an unrelated website.
3. Check a Bank Statement
Associated Bank’s routing-number guide also lists bank statements as another place where a routing number may appear. If you’re viewing a paperless statement, Associated Bank’s digital-banking FAQ explains how to download statements from the Documents area.
4. Call Associated Bank
If the transaction is large, unusual, or time-sensitive, verification is worth the extra minute. Associated Bank currently lists Customer Care at 800-236-8866. Ask specifically which instructions apply to the transaction you’re making.
Michael’s Take
The number is easy. Matching the number to the transaction is the part that matters. If the form says ACH or direct deposit, verify the routing and account numbers. If it says wire transfer, stop treating the check as the instruction sheet and confirm the wire details first.
Does Associated Bank Use Different Routing Numbers by State?
Not across Associated Bank’s core Midwest footprint. Associated Bank’s routing-number guide says that because the bank primarily operates in Illinois, Minnesota, and Wisconsin, it uses the same routing number for all of its banks: 075900575.
That makes the lookup simpler, but it does not eliminate the need to verify the transaction type. A bank can use one ABA routing number across its branches while still providing separate instructions for certain wire transfers or international payments.
Which Number Should You Use for ACH, Direct Deposit, and Wires?
This is where I would slow down. The old version of this page treated one routing number as the answer to almost every transfer question. That is too broad for a wire-transfer instruction.
| Transaction | What to use | What to verify |
|---|---|---|
| Direct deposit | 075900575 plus your account number | Confirm the account number and account type before submitting payroll or benefit instructions. |
| ACH payment or transfer | 075900575 plus your account number | Confirm the receiving account and whether the form is asking for ACH details. |
| Domestic wire | Use Associated Bank’s current wire instructions | Confirm the wire-routing instructions, beneficiary details, timing, and any other required bank information before sending. |
| International wire | Use Associated Bank’s current international-wire instructions | International payments can require SWIFT/BIC and intermediary-bank details in addition to beneficiary information. Confirm the complete instructions with the bank. |
Associated Bank’s current digital-transfer instructions also show why the distinction matters. When you add an external U.S. account in Associated Bank Digital, the bank asks for the other bank’s routing and account number. The routing number is an identifier within a particular transaction flow, not a magic number to paste into every money-movement form.
Wire Transfer Check
Before sending a wire, verify the instructions with Associated Bank and compare the recipient name, account number, bank information, and transfer type. Associated Bank’s wire guide shows that USD international wires use additional recipient-bank and SWIFT-related fields. Confirm the bank’s current instructions for your exact payment. Do not rely on an old screenshot, a remembered SWIFT code, or a routing number copied from a check.

Associated Bank Routing Number Mistakes to Avoid
I’ve seen clients run into problems after using the wrong banking number. The fix is not complicated, but it needs to happen before the money moves.
- Do not confuse the routing number with your account number. The routing number identifies the bank; the account number identifies your account.
- Do not assume every bank uses the same routing number in every state. Associated Bank says it uses 075900575 across its Illinois, Minnesota, and Wisconsin banks, but other banks may use regional numbers.
- Do not assume ACH instructions equal wire instructions. Verify the transaction type and the bank’s current wire details before a wire.
- Do not send your routing number and account number in response to an unsolicited email or text. A routing number is bank-identifying information, but your account number is private account information.
- Do not copy an international-wire code from an old article or image. Confirm the bank’s current international instructions for the exact payment.
Final Check Before You Send Money
For Associated Bank, the number to remember is 075900575. But the better habit is to remember the question that comes before the number: What kind of transaction am I making?
For a check, direct deposit, or ACH setup, verify the routing and account numbers. For a wire, verify the bank’s current wire instructions. That small distinction is what turns a correct-looking number into the correct instruction.
