About Banking in WI
WI is home to 35 financial institutions, including major national banks, regional banks, and local credit unions. Each institution has a unique 9-digit ABA routing number used for electronic transactions, wire transfers, and direct deposits.
How to Find Your WI Bank's Routing Number
You can find your routing number on your checks (the first 9 digits at the bottom left), through your bank's mobile app, or by searching our directory above. Make sure to use the correct routing number for your specific branch and transaction type.
About SWIFT Codes in WI
SWIFT codes (also known as BIC codes) are assigned to individual banks, not to states or regions. Each bank that participates in international wire transfers has its own unique SWIFT code. You can find the SWIFT code for any WI bank by clicking on its name in the table above.
Note: Not all banks have SWIFT codes—smaller community banks and credit unions typically don't offer international wire transfers directly. In such cases, they may use a correspondent bank's SWIFT code for international transactions.
Using Routing Numbers for Transfers
- Domestic transfers (ACH): Use the 9-digit ABA routing number shown above
- Domestic wire transfers: Usually the same routing number (verify with your bank)
- International wire transfers: You'll need the bank's SWIFT code plus the routing number
