The following is a general breakdown of the digits in a checking account number:

This number uniquely identifies the bank that issued the account. It is also known as the issuer identification number (IIN) or the institution identification number (IIN).

2. Account Number: The next 6 to 10 digits of the checking account number represent the account number itself. This number is unique to the account holder and is used to identify the specific account within the bank.

3. Check Digit: The last digit of a checking account number is a check digit. This digit is calculated using a specific algorithm to ensure the accuracy of the account number. It helps prevent errors in data entry and is used to verify the validity of the account number.
