A routing number is a unique nine-digit number that acts as an address for your bank, identifying the bank or credit union in a financial transaction. It is used for electronic transactions such as funds transfers, direct deposits, digital checks, and bill payments. The routing number is not written on debit cards. Here are some ways to find your routing number:

• On a check: You can find your routing number in the bottom left corner of a check. It’s the first nine digits of the long line of numbers.
• Online banking: You can log into online banking, select an account, and click on Account Numbers & More to find your routing number. You can also log into your account on the U.S. Bank Mobile App, select the desired account, and select Account information to find your routing number.
• Bank statement: You can use the third and fourth digits of your account number to determine your routing number. You can find your account number in the top of the right column of a bank statement. In the example, you would use 34 to determine your routing number using the chart below. 34 corresponds to the routing number 074000078.
• Contact your bank: If you are unable to find your routing number, you can contact your bank for assistance.

Its important to note that routing numbers are required only for electronic transactions such as direct deposits, and not for debit card or credit card purchases.
