Can Banks Have Multiple Routing Numbers?

If banks operate in more than one state, it’s possible they use multiple routing numbers. Big national banks such as Wells Fargo, Citibank and Bank of America use different routing numbers for customers in different states. The one you use depends on where you opened the account. Bank of Oklahoma customers only need to remember one routing number, however.
