A routing number, also known as an ABA (American Bankers Association) number, is a nine-digit code printed on the bottom of checks. It identifies the financial institution where the check was issued and helps ensure the funds are transferred to the correct account.
Knowing where to find the routing number on a check is crucial for completing wire transfers, setting up direct deposits, and otherwise managing your finances efficiently. Historically, routing numbers were crucial in the development of the automated clearing house (ACH) network, which enables electronic funds transfers between banks.
