The U.S. Postal Service reminds the public that voting in its Stamp Encore contest will close at midnight on Sept. 30.

The Postal Service created the contest to celebrate its 250th anniversary and gear up to celebrate the country’s 250th anniversary.

It is inviting folks to help select a stamp pane from the past for reprinting as part of the 2026 stamp program.

The Postal Service chose 25 stamp panes from some of its best-selling and most popular releases of the recent past.

Voting is open both online and by mail. To vote online, visit stampsforever.com/vote or print a paper ballot from the website and mail it.

Participants can vote as many times as you want.

The Postal Service plans to announce the winning stamp design in May at the Boston 2026 World Expo philatelic show to coincide with America’s 250th anniversary celebrations.

Until then, the results will be a secret.
