What is NOT included in the required information for purchases made without an account?

The correct answer is the personal identification number, which is not included in the required information for purchases made without an account. When customers purchase instruments, particularly financial instruments like money orders, the information typically required includes the date of purchase, types of instruments purchased, and serial numbers of those instruments.

The date of purchase is crucial for record-keeping and compliance purposes, providing a timeline that can be referenced later in case of any issues or inquiries. The types of instruments purchased identify what was bought, which is important for tracking the movement of such instruments and ensuring compliance with regulations. Serial numbers are similarly significant, as they help in identifying and tracing specific instruments against reported theft or fraud.

Unlike these elements, the personal identification number is not a standard requirement for documenting purchases in circumstances where an account is not involved. Typically, personal identification numbers are more relevant in the context of account-based transactions or in scenarios where identity verification is needed beyond the purchase itself. This distinction is vital for compliance scenarios, as it delineates what information is necessary for proper reporting and monitoring under the Bank Secrecy Act.
