The bank routing number (also known as the ABA routing number, where ABA is an abbreviation for the American Bankers Association) is a unique identification number that is assigned to your bank. Routing numbers are used by banks to identify their accounts in the same way that people in the United States have a Social Security number or a Taxpayer Identification Number.
In the bottom left corner of each check, you’ll see a nine-digit number that corresponds to your routing number. The second set of numbers written on the bottom of your checks is your individual account number (which is normally between 10 and 12 digits long).
