PS Form 6401 is used for what purpose?

• A. Delivery notice
• B. Refund processing
• C. Money order inquiry in case of a lost or stolen money order
• D. Money order inquiry

Answer: (C)

PS Form 6401 is the official money order inquiry used when a money order is lost, stolen, or not received. It helps USPS trace the money order and, if appropriate, arrange a replacement or refund. The form collects information about the money order—its number, amount, purchase date and location—as well as details about the purchaser and recipient. Providing these details speeds up the trace and protects the purchaser from loss. This is why it’s the best choice: it specifically covers inquiries arising from a missing or stolen money order. The other options don’t fit because they refer to delivery notices or generic money order questions, whereas this form is focused on locating and replacing a lost or stolen money order.
