where is the check number at the bottom of a check
Across the bottom of the check, a series of numbers appear at the left-hand side, extending almost to the other end of the document. The first series of numbers at the bottom of the check represented the bank routing number, a 9-digit code which denotes the specific banking institution where you keep your checking account. The same routing number is written across the top middle of the check in small type, a fraction code which displays the routing number in a different way.
