Stamps
Natural patterns
The “Natural patterns” set is being expanded to include the motifs “Vine leaf” and “Mushrooms”. The new stamps make fine natural structures visible and invite you to explore them.
Rich Content Section
Nature is full of intricate structures that are often hidden away: delicate veins in leaves, gills under mushroom caps or patterns of ice and wood. The new “Vine leaf” and “Mushrooms” stamps bring these details to life on the stamp in miniature format. They show how small shapes and lines create whole arrangements and raise awareness of the beauty in detail. The stamps are setting new technological priorities: for the first time in Switzerland, a data matrix code has been integrated that makes sorting easier and increases security against forgery, without restricting design freedom. The stamps combine nature observation, creativity and modern technology in a small collector’s item.
Swiss stamps feature data matrix codes for the first time
“Vine leaf” and “Mushrooms” are the first Swiss stamps to feature data matrix codes − a technological innovation. They may seem insignificant at first glance, but they will have a big impact in practice.
Important: The stamps are only valid for franking if they have a data matrix code.
Stefan Bühler, Head of Stamps & Philately, explains:
“The newly introduced dynamic data matrix code is a Swiss Post market test that will run from March to June 2026. Afterwards, a survey will be held to record the responses, and the results will be analysed.
The test will examine both the technological functionality and the interaction between innovation and design. The code will significantly improve recognition at processing facilities, increase protection against forgery and prevent people from abusing the system by using the same stamp multiple times. It will also allow for maximum freedom in design: as long as the code is integrated, artists will be free to choose the stamp’s shape and colour.
Switzerland’s market test follows in the footsteps of countries such as Germany, Finland, the UK and France, and will examine the best way to combine modern technology with stamp art.”
