Effective January 17, 2027, the Postal Service™ will revise Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM®) section 509.3.2.3 to eliminate traveler’s checks as a method of payment for purchasing money orders.
Counterfeit mechanisms have become an increasing source of fraud in financial instruments. To protect revenue, the Postal Service is eliminating traveler’s checks as a method of payment accepted by the Postal Service.
Although this revision will not be published in the DMM until January 17, 2027, this standard is effective immediately.
