Stamp Announcement 23-20: Endangered Species Stamps


On May 19, 2023, in Wall, SD, the United States Postal Service® will issue the Endangered Species stamps (Forever® priced at the First-Class Mail® rate) in 20 designs, in a pressure-sensitive adhesive (PSA) pane of 20 stamps (Item 483800). These stamps will go on sale nationwide May 19, 2023, and must not be sold or canceled before the first-day-of-issue. The Endangered Species commemorative pane of 20 stamps must not be split and the stamps must not be sold individually.

Featuring 20 different endangered animals, these 20 stamps pay tribute to the Endangered Species Act and mark the 50th anniversary of the legislation. The stamp art showcases photographs of endangered animals found within the 50 states and American territories and possessions, as well as two North American species living near U.S. borders. The images are among more than 13,000 in photographer Joel Sartore’s “Photo Ark,” his project to document as many animal species as possible. Art director Derry Noyes designed the stamps with Sartore‘s existing photographs.
