Step 1: Find your Routing & Transit Number

The first 9 numbers from the left at the bottom of your check are your Routing & Transit Number. This number is always 9 digits.

Step 2: Find your Account Number

The numbers after the Routing Number are your Account Number. If you notice extra zeroes before or after your account number, please include them as part of your account number.
