Discontinuance of the Priority Mail Pre-Paid Flat Rate Stamped Envelope

Since 2003, the United States Postal Service^® has produced the Pre-Paid Flat Rate Stamped Envelope. This is a Priority Mail^® Flat Rate envelope that features the Castillo de San Marcos Priority Mail stamp image (issued on January 24, 2021, St. Augustine, FL 32084) and is available only through The Postal Store^® at store.usps.com/store/home.

Orders and usage of the envelope have steadily declined over the past several years while production and fulfillment costs have continued to rise. The Postal Service™ plans to discontinue further production of the Priority Mail Pre-Paid Flat Rate Stamped Envelope.

The Priority Mail Flat Rate Stamped Envelope will remain available at store.usps.com/store/home until January 2022 or while supplies last. Customers who currently use these envelopes are encouraged to place any desired orders before supplies are depleted. For future orders, customers who order the Priority Mail Pre-Paid Flat Rate Stamped Envelope will be redirected to the Priority Mail Forever^® Pre-Paid Flat Rate Envelope at store.usps.com/store/home.

The Priority Mail Forever Pre-Paid Flat Rate Envelope has Forever postage applied to the envelope. The customer’s return address is printed in the upper left corner of the shipping label and includes USPS Tracking^®.
