Routing Number Definition.

Routing numbers (or ABA numbers) are used with a checking, savings, or other bank account, and they associate a financial institution with an account. This number is used to determine where to route funds to or from. Anyone seeking a direct deposit from a company will typically have to provide a routing and account number. Routing numbers are also used when ordering checks or when performing a domestic wire transfer.
