The Bank Routing Number

The bank routing number is a nine-digit code assigned to a financial institution. It serves as an identifier for the bank where the checking account is held.

When you initiate a transfer or deposit, the routing number helps direct the funds to the correct bank.

To locate the routing number for your bank, you can refer to your checks or contact your bank directly. Many online banking platforms also provide easy access to the routing number.

The Account Number

The account number is a unique identifier that distinguishes your individual checking account. It typically consists of a series of digits, although some banks may include letters or special characters as well. The account number is crucial for accurately identifying your specific account when conducting financial transactions.

Your account number is confidential and should be safeguarded to prevent unauthorized access. It is crucial to double-check the account number when initiating any financial transactions to ensure accuracy and avoid potential issues.
