How To Find Your Union Bank Routing Number
There are a few ways to find your routing number. If you remember which state you opened your account in, use the chart above. You can also do the following:
On a Check
If you have a U.S. Bank checking account, you can find your routing number on a check — the check routing number is the first nine numbers in the lower left corner.
Through Online Banking
Since Union Bank is now U.S. Bank, you can visit U.S. Bank’s website or mobile app to find your routing number. Follow these steps:
- Log in to your U.S. Bank online account.
- Navigate to your account settings or details.
- You should be able to spot your routing number close to your account number.
By Contacting Customer Service
You might not have a check or access to online banking, however, so you can also call U.S. Bank any time at 800-872-2657 to find the routing number for your account. A representative will be able to look up the number and provide it to you over the phone.
Union Bank Routing Numbers for Wire Transfers
To send a wire transfer, you’ll need your U.S. Bank routing number. Customers who wish to send a wire transfer outside of the United States might also be asked to provide a SWIFT code, which is made up of both letters and numbers. This code always contains between eight and 11 characters.
Here are the details you’ll need to supply for wire transfers:
| Transfer Type | Routing Number | SWIFT Code |
|---|---|---|
| Domestic wire transfer | Varies by state | N/A |
| International wire transfer | Varies by state | USBKUS44IMT |

You’ll need your routing number for a few different banking activities, including:
- Bill payments: Set up automatic payments for your monthly bills — utilities, rent or mortgage.
- Direct deposit: Provide your routing and account number to your employer or government agency to receive direct deposit payments.
- Wire transfers or ACH transfers: Use your routing number to send or receive money transfers.
