USPS to Issue Triangular Postcrossing Stamps — Four Bright Designs, Global Forever Rate

It has been reported that the United States Postal Service will issue new Postcrossing stamps — and yes, they’re triangular. After years of requests from the Postcrossing community and behind‑the‑scenes work with USPS, the announcement lands like a happy surprise: a celebration of the snail‑mail joy that keeps people sending postcards around the globe. Community pride? Big. Smiles all around? Absolutely.

Design: triangles, bold color, tiny details

The stamps come in four different triangular designs, meant to be placed on a postcard corner for a distinctive look. They’re global forever stamps — one stamp covers the international postcard or letter rate — and the artwork is described as bold, playful, and full of small delights. Antonio Alcalá designed the stamps and Jackson Gibbs illustrated them, producing an energetic, unmistakably Postcrossing look. Triangular stamps are a rare format for USPS; who wouldn’t want to stick one on the corner of a postcard and make someone’s day?

Launch and meetups in Boston (and nationwide availability)

It has been reported that launch day is May 26, 2026, with a commemorative ceremony at the Boston 2026 World Expo and daily Postcrossing meetups during the show — all free and open to visitors. Can’t make it to Boston? No problem: like other USPS releases, the stamps will be available online and at post offices across the country. Expect more details and merch in the lead‑up, but for now, collectors and postcard lovers alike can start planning which corner of the card will get the first triangle.
