Sample check used to demonstrate location of where your ABA routing number might be.
You can find your ABA Routing Number and Checking Account Number within the string of numbers located at the bottom of one of your checks. Make sure you are using a check and NOT a deposit slip, since the numbers may not be the same.

Your ABA Routing Number is the set of 9 digits starting with the numbers 1, 2, or 3 always located between these symbols:

Your bank account number is a different set of digits, that may be listed AFTER the routing number or BEFORE the routing number, depending on your bank. Your bank account number will ALWAYS be followed by this symbol:

The remaining digits designate your check number.  See sample check above.

If you have any questions, contact your bank or financial institution to verify in which order your numbers are being displayed on your checks.
