A bank routing number, also known as an ABA number, is a nine-digit code that identifies your bank or credit union. It appears at the bottom of your checks, typically on the left side, and may also be available through your bank's online or mobile banking platform.
Your bank account number identifies your specific account and is printed at the bottom of your check, usually to the right of the routing number. You can also find it on bank statements or in your online or mobile banking account. If you're unsure which number to use, contact your bank for assistance before submitting your payment.
