An “account number and routing number on check” refers to the pair of numeric codes printed on a check that identify the financial institution and specific account associated with the check. For example, a check might display “Routing Number: 123456789” and “Account Number: 987654321”.
These numbers are essential for processing electronic payments, ensuring funds are transferred to the correct account. They streamline financial transactions and reduce manual errors. Historically, they emerged with the development of the Automated Clearing House (ACH) Network, which facilitated the electronic exchange of financial data.
