How to Find Your Bank Routing Number in Seconds

Bank routing numbers are made up of a nine-digit code that is used to identify your financial institution in a transaction. It’s the first set of numbers printed on the bottom left side of your checks. An account number is usually 10 to 12 digits long and is specific to your personal bank account. It’s the second set of numbers printed on the bottom of your check, to the right of the bank routing number.

You might not often think about those little numbers on checks, but they’re critical to the banking system.

These numerical strings are the U.S. bank routing number, the account number and the check number. The bottom left corner is where you’ll usually find the routing number on a check, as seen on the following check image.
