For a monetary instrument purchase, which information is required from a purchaser who does not have an account?

When a purchaser who does not have an account is engaged in the purchase of a monetary instrument, it is critical for financial institutions to comply with regulatory requirements, which include properly identifying customers to prevent money laundering and other financial crimes.

In this scenario, the requirement for a Social Security Number or alien identification number is particularly important. This information is used to help verify the purchaser's identity and ensure compliance with the Bank Secrecy Act (BSA) and related regulations. By obtaining either of these identification numbers, financial institutions can conduct necessary due diligence, including screening against various financial crime databases.

Acquiring this information not only facilitates appropriate record-keeping but also assists in the organization’s ability to report suspicious activities involving monetary instruments, as required by regulations. Thus, having the purchaser's Social Security Number or alien identification number provides the necessary identification needed to process the transaction legally and securely.
