An account number is a unique identifier assigned to each bank account. It is typically printed on checks and is used to identify the account from which the check is drawn. One such example is a nine-digit number located at the bottom left corner of a standard personal check in the United States.
Account numbers serve a crucial role in banking transactions. They allow banks to process checks and other financial transactions accurately and efficiently. In the past, account numbers were handwritten, but advancements in technology have led to the use of automated printing systems that reduce errors and streamline the banking process.
