A “routing number on checks” is a unique 9-digit code printed on the bottom of checks, identifying the financial institution and branch where the account is held. For instance, a check from “ABC Bank” may display the routing number “123456789”.
Routing numbers play a crucial role in the electronic processing of checks, known as Automated Clearing House (ACH) transactions. They ensure funds are accurately and efficiently transferred between banks, facilitating smooth financial operations.
