Effective November 19, 2021, the Postal Service™ will remove the requirement to complete PS Form 6401, Money Order Inquiry, for local money order replacement requests. If a money order is mutilated or damaged, and the customer has the damaged money order and the original customer receipt, the Postal Retail Unit may issue a no-fee replacement.
PS Form 6401 is still required to initiate Money Order inquiries and for replacements when the customer does not have the original receipt.
The Postal Service will incorporate this revision into the next online edition of Handbook F-101, Field Accounting Procedures, where appropriate.
