Frequently Asked Questions
What is this project?
This is a social experiment and personal challenge started by two students in Switzerland. We send 3D-printed badges to random addresses worldwide to "collect" countries through human interaction rather than travel.
Environmental commitment
We care about our planet. All letters are sent using the Swiss Post "Pro Clima" service, which offsets CO2 emissions. Furthermore, our 3D-printed badges are made from recycled or bio-sourced materials whenever possible.
How do you find addresses?
Addresses are selected entirely at random using public data from online maps and directories (like Google Maps). No personal data is stored or used beyond the purpose of mailing the letter.
My country is not listed
If your country is not listed and you would like us to send a letter there, please let us know by email code@ezak.ch or DM us on Instagram @ezak.ch. The address will be chosen at random like the other countries.
How can I participate?
If you received a letter, simply send the code written on the badge to code@ezak.ch or DM us on Instagram @ezak.ch. Your country will then be updated to "Successfully received" on this map!
