ACCOUNT numbers are different for every individual account. MOST banks assign account numbers in such a way that it is possible to tell a checking account number from a savings account number from the number itself. How to tell is not public information. If you are referring to th banks ROUTING number, it may or may not be the same for checking and savings accounts. That said, large banks have MULTIPLE routing numbers depending on WHERE your account was opened. My bank has at least a dozen routing numbers just for accounts opened in Ohio. STEVEN F · 6 years ago.
